XPages remove documents on server and trigger partial refresh - xpages

I am struggling with the following.
On my XPage I have a viewpanel component, but it is not bound to a notesview datasource, but to a hashmap stored in viewScope. Reasons for this is beyond scope of my question.
Since the lines in my view are not actually linked to the documents I cannot use the standard checkboxes and the related getSelectedDocIds. I do however want a way to remove the selected documents. I have a column with checkboxes containing the unid of the corresponding row.
So long story short. I have an array of unids and want to perform an action that does the following:
Display a dijit.Dialog asking for confirmation
If OK clicked call a function that does the following:
Remove the documents based on the unids
Refresh the viewpanel
I am thinking of the following 2 solutions, but in doubt what would be best (maybe a third, even simpler solution?)
Have the OK button of the dojo dialog call a function that does an XmlHttpRequest to an XAgent or plain old LS agent
Have the OK button trigger an eventhandler that runs on the server as described by JeremyHodge here. But how would I pass the unids as parameter and refresh the view afterwards?
Thanks!

Cant you just make use of the extension library dialog with the dialog button control. In this button control you can then
A third option would be to add a column to your datatable/view which contains checkboxes. On the onchange event of these boxes you add an eventhander which adds the value to a viewScope variable.
A button on the bottom (or top.) of the page you add the code you need to remove the selected items from the hashmap, delete the documents associate with the selected id's. this button can be a ordinary button with a partial refresh on the viewpanel. When you run into the bug that you cant use buttons in a dialog please use the extension library dialog control because this fixes that issue for you.
If the current user does not have the correct access level to delete documents you could use the sessionAsSigner global (assuming the signer of the design element has the correct access levels).
This way you dont need to go call an xAgent by xmlthttprequest and can stay with the default xpage methodology.
I hope this helps in some way

I would second #jjbsomhorst in the use of the extension library for the dialog box - if you use one at all. Usually users don't read dialog boxes. So the approach would be add the column with the checkboxes, but don't bother with an event handler, but bind them ALL with their value to ONE scopeVariable. On submission that variable will then hold an array with the selected UNID.
Then render a page that lists these documents and have a confirm button. While the new page affords a server round-trip the likelihood, that users actually pay attention is way higher. What you can do:
Have the normal page that renders the dialog with editable checkboxes and when the user clicks "Delete" you set something like viewScope.confirmDeleteMode=true; and use that as condition for the checkboxes and make them read-only AND set the class of the selected rows to "morituri" which in your CSS would have something like .morituri { color: white; background-color : red; font-weight: bold } and a new button "Confirm Delete" (and hide the Delete button).
This way you only have one page to deal with.

I went for option 2, which has the possibility to provide the partial refresh id. I passed the unids as a submitvalue like:
function doRemove(unids){
XSP.executeOnServer(ISP.UI.removeEventID, ISP.UI.removeRefreshID, {
params: {
'$$xspsubmitvalue': unids
},
onComplete : function() {
//alert('test')
}
});
}
The ISP.UI.removeEventID performs the following code:
var unids = context.getSubmittedValue();
removeDocuments(unids); //SSJS function performing the actual delete
viewScope.reload = 'reload' //triggers the hashmap to be rebuild based on new documentcollection

How to change xpage form for new document?

Right now I am working on a Xpage which displays data from a domino document. Based on the form of the document different fields will be displayed.
Now I want to create a "New" function. My idea here is to set the view I am previously using in edit mode.
Additionally, I want to add a radio button which enables a user to choose the form of the document he wants to create.
Based on this radio button the document form should change which should result in the elements displayed on the page changing too.
Overall if I switch between the radio button options and hit save, a new document will be created with the right form.
Yet my problem is that my elements in my view won't change dynamically. So if I switch my form there will still be elements/controls displayed for the default option but not the selected form.
My idea was to create an onChange-event for my Radio Button Group.
My questions here would be: How can I change my formValue for the Xpage (new document) and then reload it with the new set value?
Thanks for your explanation.
I understand you have one XPage suitable for multiple forms, I assume using a Switch control and custom controls per form. About the New button, you could try first to have 3 New buttons, each for a separate form, and you create a URL like yoursite.com/xpage.xsp?action=newdocument&form=someform
When the user clicks the button, your page can read the parameters (param.action and param.form) and act accordingly. Or do you intend to update the current page using partial refresh, as a single page approach?

xpages embedded view or view panel

I know it is a very simple question , but I'm trying to see the difference between a view panel ( that I drag from the Container Controls ) and an embedded view.
How can I add an embedded view on my xpages?
Or the 2 items are one and the same.
The reason why I'm asking this question: I have a view panel on my xpage ( I thought it is like an embedded view in clasic lotus notes programming ) where I have listing some docs. The first column is categorized based on the UNID document.
I noticed if I compose again another document, this view contains all the previous docs., and all the UNID categorized. The view panel isn't empty.
In lotus notes programming:
If I have a main form and a computed text field with #Text(#DocumentUniqueId) and some button for composing another form ( of course, when clicking the button I saved the main form to obtain the UNID ), and this form has the same text field name as the previous - I'm passing the UNID to this second form. If the main form contains an embedded view listing all documents saved from the second form I will use the first column categorized and hidden with the name of the field from the second form ( which will contain the UNID ). If I save and close the 1st main, and then I'll compose another main form, the embedded view is not listing the previous documents already saved.
Well, this view is already created.
I did drag and drop this view in myxpage. I have a button inside myxpage that shows a dialog. Here a datasource is declared, the dialog containing some fields. In the main xpage ( where is defined another datasource ) there is a computed field which takes the UNID of the document. Before I click the dialog I save the first datasource, to pass the value UNID to other field inside the dialog.
I save the datasource from the dialog & close the dialog, and then the view panel ( which is the view from the lotus notes classic presented above ) lists the doc. If I close the main xpage ( save it if is a new one ) and then open another main document, the view isn't empty, it contains the previous document lists. ( I tried also to hide it, if the xspDoc is new. But when I try adding other docs. from the dialog, the view panel lists also the previous documents from the previous doc., even if the UNIDs are distinct )
Thanks in advance.
To explain this best, it's good to consider what a view and an embedded view in Notes Client is. A view determines the look and feel, like a View Panel and by default will show all documents found by the selection criteria. So in this case the documents available correspond to a dominoView datasource bound to the underlying view with no additional criteria defined.
An embedded view still uses the view to determine the look and feel, but will not display the first column (that's effectively a property of the embedded view "control" in Notes Client). In the View Panel you choose which columns display, so you would need to code that yourself on the View Panel, where you choose which columns to display. The embedded view also has a property to define the single category. But the View Panel and other repeating containers (like Data Table and repeat control) don't restrict the data available, that's done by the datasource - a dominoView or e.g. a ViewEntryCollection for anything other than the View Panel. So in that you set the filter.
However, a new document does not have a UNID, so it cannot restrict what is displayed. Instead, I think a good approach is to set the visibility so the View Panel is only displayed if it's not a new document. You can use loaded, if you fully reload the page after save, or else rendered.
First off, this is not a stupid question.
I am assuming you are using a self implemented parent response system and have a view sorted by the parent UNID. Under the data source of the view panel, find the the "filter by category name" option. there compute the UNID value, or category value you are searching for.
Steps:
insure that the background view is categorized (ascending order is best to insure that this works, though I doubt it is needed)
drag (my favourite is the dynamicViewPanel) a view control onto the xpage.
Under Properties/Data there is a place to calculate the value of the category to show. If you want an exact match, check the exact match check box.
If you mistype the category value or the value is not there, then no documents will be shown.
if you put in an empty value all documents are shown (at least in the tests that I can remember)
if documents are returned, the categorized column is automatically hidden.
EDIT
If you are reading the value from a field, you can use the code:
xspDoc.getItemValueString("fld");
If you are searching based on the UNID, again, hide the viewPanel if the document is new. If the value is not yet set, also hide the panel.
If you have two custom controls, even if a custom control is embedded in the second, you cannot easily have one custom control access the values of the datasource in another. I am sure there are ways to trick this into working, but in this case, use a viewScope variable to access the values and possibly an onLoad, onChange or onSave event to update the viewScope variable. Make sure to verify that the result is not null or empty by either printing it out to the server log or another field.
Final Edit after question edit/expansion
These are the steps that I would take to do what you described.
You have your parent document XPage. Insert all fields for this Xpage.
Drag a dynamicViewPanel onto the XPage. If parentDoc is New, then hide.(this could be a custom control in theory, but if you are having trouble, try it without for the sake of trouble shooting.
Set dynamicViewPanel datasource to ignoreReqeustParams.
Calculate the datasource and setting the "Filter by category name" filter. When computing this, for the sake of ease and troubleshooting, print this value out to the server, or other logging mechanism. You can delete it later.
Verify that the correct UNID/Value is being inserted into the document you create in the dialog.
If you are using a scoped variable to hold the filter value, be sure you are using viewScope and not appliationScope or sessionScope.
if you are using a custom control and standard parameters (not scopedVars), verify that the compositeData variable is being updated with a log or server print.
Consider setting Dialog Properties/AllProperties/basics/refreshOnShow to true
Play with the partial refresh option for the dialogOpen action, test a full vs partial refresh.
Remember to set the ignoreRequestParams for the document you are creating in the dialog to true
Consider making the new document data source created in the Dialog to request scope.
And of course consider and test all datasources being defined on the XPage on not some here, some there.
Verify that you are taking the value of the UNID from the main document and not the new dialog document by mistake!
Those are all of the tips I can think of right now, pretty much in the order I'd try them in. If that does not help, then I suspect there is a piece of this puzzle that you are not including in the question. Remember, try to keep things as simple as you can. You can over think things, make things harder than they need be.

Inline Editing of View data used in a repeat

I have a repeat control using a view as the datasource with a custom control within the repeat. The custom control is made up of a panel with two tables. One table has computed fields with an Edit button and the other has editable fields with a Save and Cancel button. The Edit and Cancel buttons work as needed, but the Save button gives a NotesDocument.save() is null error. I have already narrowed the issue down to the error occurring on the edoc.save() line by commenting out all prior lines. I even tried to do an edoc.lock(), but got the same error.
var edoc:NotesDocument = database.getDocumentByUNID(viewScope.get('docid'));
edoc.replaceItemValue('Ext_1',viewScope.get('ext_1'));
edoc.replaceItemValue('DID',viewScope.get('did'));
edoc.replaceItemValue('Mobile',viewScope.get('mobile'));
try {
edoc.save();
} catch(e) {
print(e.toString());
}
The storage of a DocID in the viewScope and a repeat control doesn't seem right. You want to add a custom property to your custom control called DocID and then instead of
database.getDocumentByUNID(viewScope.get("docid"));
You do:
database.getDocumentByUNID(compositeData.DocID);
This was you can be sure that you get the document that was in that view for that row.
What you also might consider, instead of all the manual steps (the ones you commented out) have a panel with a DocumentDataSource and then simply bind your input fields to that one. Handover of id via custom property and "IgnoreRequestParameter = true
Then you simply do a rowDoc.save() (presuming you named the datasource rowDoc) and you don't need to recycle anything. Let us know how it goes.

How can we use ONLY client side script for "hide/whens"?

I am working on a large, worldwide application, which includes access from areas of low bandwidth. As such, I want to use a minimum of SSJS or partial refreshes for all the complex hide/when calculations. Here is what I have so far for a simple "hide/when":
A Yes/No radio button, with CSJS to show a panel ("Yes") or hide the
panel ("No").
The panel has a formTable inside it, and the values are shown or hidden, as per #1.
In the XPage's onClientLoad, the following code is run:
// "getRadioValue" is a simple script to return the value of a radio button
var v_value = getRadioValue("#{id:radioButton}");
v_div = '#{javascript:getClientId("radioButtonPanel")}';
// show or hide div simply use dojo to change the display of the panel
if (v_value == 'Yes') {
showDiv(v_div);
} else {
hideDiv(v_div);
};
For a new document, the onClientLoad script will hide the "radioButtonPanel" successfully. Changing the radio button to "Yes" will show the radioButtonPanel, just as clicking "No" will hide it. It works great! :-)
Once the document is saved and reopened in read mode, though, the onClientLoad CSJS event should read the saved value in the document, and decide to show the panel or not. When the document is opened in edit mode, the onClientLoad fires, reads the radioButton value and successfully shows or hides the panel.
This is what I've tried so far, to get it to work in read mode:
In CSJS, using "#{javascript:currentDocument.getItemValueString('radioButton'}" to get the value,
Doing some calculations in the "rendered" or "visible" properties, but that's SSJS and, if hidden, prevents any of the "show/hideDiv" CSJS visibility style changes.
Adding an old fashioned "div" to compute the style (which is what I used to do before XPages), but since I can't do pass-thru html any more, I can't seem to get a CSJS calculation for the style. Ideally, I can do something like this:
<div id="radioButtonPanel" style="<ComputedValue>">
Where the ComputedValue would read the back end value of the document, and decide to add nothing or "display:none".
Note that I don't want to use viewScopes, since this long form would need many of them for all the other hide/when's.
Is there any way to make this 100% CSJS? I feel like I'm very close, but I wonder if there's something I'm just missing in this whole process.
First, rather than computing style, I'd recommend computing the CSS class instead -- just define a class called hidden that applies the display:none; rule. Then toggling visibility becomes as simple as a call to dojo.addClass or dojo.removeClass.
Second, I see that you're using the #{id:component} syntax to get the client ID of the radio button but using SSJS to get the client ID of the panel. Use the id: syntax for both; this is still just a server-side optimization, but if there are many instances of these calculations, it adds up. Similarly, replace #{javascript:currentDocument.getItemValueString('radioButton'} with #{currentDocument.radioButton}. Both will return the same value, but the latter will be faster.
Finally, any attribute of a pass-thru tag (any component with no namespace, like xp: or xc:) can still be computed, but you'll need to populate the expression by hand, since the editor doesn't know which attributes for valid for these tags, and therefore doesn't provide a graphical expression editor. So if the ideal way to evaluate the initial display is by wrapping the content in a div, the result might look something like this:
<div class="#{javascript:return (currentDocument.getValue('radioButton') == 'Yes' ? 'visible' : 'hidden');}">
<xp:panel>
...
</xp:panel>
</div>

The buttons in a repeat don't hide/show after refreshing the panel the repeat is in?

I have a repeat that has buttons embedded in it. The repeat is in a panel. When the user clicks a button the button should hide/show (I partial refresh the panel). The repeat is tied to a Domino view and I see the other values that I from that view get updated in the repeat, so, it does not seem like a view index issue (I refresh the view index in my code.)
If I use context.reloadPage() in my button onclick code then the buttons will hide/show like they should, but, that seems like I am using a sledge hammer! Any suggestions on how to get the buttons to recompute the visible property when the panel that holds the repeat is rendered? Another strange thing is that the visible property gets computed three times whenever I refresh the panel that holds the repeat.
thanks, Howard
I think your looking for
getComponent("<id>").setRendered(true / false);
Hi For Repeat control's entry is used to make our head hard. Because handling the entry by SSJS, we can get the value and set the value. But rendering part, id of the repeating component are same for all. So if we try to give reder as false. It hides all of our repeating component.
Try to use the following., [Put this in button onclick, and see the value of below]
var entryValue= getComponent("repeat1").getChildren().get(0).getValue()
getComponent("inputText1").setValue(entryValue)
But in client side we can easily handle. Because the id of the DOM object is unique for all repeating component.
var id1="view:_id1:repeat2:"+'2'+":button1"
document.getElementById(id1).style.display="none"
This will hide the third entry of your repeat control component.
Please see the post, You may get better idea
Found a solution. My original solution was getting values from the repeat rows (using the collection object, which was a viewentrycollection and using getColumnValues) to compute the rendered property for the buttons.
Instead, I created a viewScope variable (a Vector) that holds the state of the buttons (which set of buttons to show). This gets populated in the beforePageLoad event of the page.
The button onclick code updates this viewScope variable after performing its processing. All works very nice now. I guess it was something in the JSF lifecycle that kept the buttons from being properly updated. Using the viewScope variable works fine.
With addition to what Ramkumar said, you can use the index variable in the repeat control to identify each and every occurrences inside the repeat control. You will get more idea, if you inspect with element from firefox[You might need firebug]. Usually the field mentioned inside a repeat control itself can be considered as an array
