I'm interesting in creating a widget in Yesod with the following properties:
By default, it renders simply as some text "Title"
When moused-over, a small link "Edit this" appears on the upper-right corner
If the user clicks on the link or mouses over it, the text is replaced with a text field/area with the text in it, for editing
When the user presses ENTER, a REST request is made to the server to update the value; when the update is confirmed the form disappears and updated text is now present in the document
To a large degree, this is a strictly JS job which is mostly out of scope for Yesod. However, there is one important point: we'd like the form itself should be generated by Yesod using yesod-forms, and not wired up manually. But the situation here is a bit strange: normally forms are static, but here the form needs to be different depending on what the data is, and Yesod might need to ship a new form to the user after the REST update. Can Yesod do this? Additionally, what is the story, as far as validation is concerned?

In the simple Dialog below:
// choice of layout has no impact:
Container cont=new Container(new TextModeLayout(3, 1));
//Container cont=new Container(new BoxLayout(BoxLayout.Y_AXIS));
TextComponent firstName=new TextComponent().label("First Name").text(person.firstname);
TextComponent lastName=new TextComponent().label("Last Name").text(person.lastname);
TextComponent cost=new TextComponent().label("Cost per Session").text(person.getCostString());
cost.getField().setConstraint(TextArea.DECIMAL);
// NOTE HERE
// doesn't work: // works:
cont.add(firstName); // cont.add(firstName.getField());
cont.add(lastName); // cont.add(lastName.getField());
cont.add(cost); // cont.add(cost.getField());
Dialog.show("Edit Client", cont, new Command(CANCEL), new Command(OK));
Nothing appears in the Dialog unless I add the TextField instead of the TextComponent to my container at the NOTE HERE comment. This means I lose the nice appearance of the labelled input fields (yes I know I could label them myself, but they wouldn't look as good on different devices). My choice of layout manager at the top does not affect this issue (I've tried several). I can't find evidence online to conclude there's an incompatibility here, adding TextComponents and other InputComponents works fine on a Form, just not in a Dialog.
I'm having the same problem in another Dialog that uses PickerComponents. The PickerComponent doesn't appear unless I add the Picker itself, and then the Picker spawned from a Dialog looks all wrong. I'm hoping the simpler code question above will answer this quandary as well.
It's worth noting I've made no theme changes and this problem is noted in both the Android and Apple skins as well as on an actual Android phone. Thanks in advance for any help!
You shouldn't do input in a Dialog as it creates a very problematic user experience. If you would like things to look like they are in a dialog you can use styles and layouts to make a Form feel like a Dialog but you shouldn't use a Dialog.
The reason this fails is a bit complicated but here are the high level problems with using a dialog:
Dialogs don't grow implicitly - This is a huge problem for text input as the component needs space to resize with input and even more so for the animated TextComponent which needs to shift things around. The size of a Dialog is determined when it's shown and that's a big problem
This becomes a bigger problem on Android where the screen resizes during input and distorts the dialog completely. It's one of those things you'll only see on the device because it's really hard to simulate the virtual keyboard.
Scrollability is hard in a Dialog and text components need a scrollable parent so you can scroll between the various edit components
Picker component uses a form of Dialog to show input and this can collide with your dialog
Dialogs are hard to get right for suspend/resume behavior. Suspend/resume happens when the app is minimized or sent to the background. E.g. say you have an incoming call while typing in the dialog. When you go back to the app we want to show the last form. If we show the dialog it will block and we won't know which parent form to show anyway. So when an app is suspended dialogs are just disposed in the default code generated in the main class. It makes more sense.
I'm new to Domino Designer. I'm trying to modify an existing application which is running on a remote server. I create a blank xPage and view in browser and it works. I add a label and view in browser and it works. I add a combo box and setup a data source for my xPage. The data source is in the current application and I'm using a view. I setup my combo to point to that data source and specify BindTo value. I view it in browser and I get Error 500 "HTTP Web Server: Command Not Handled Exception" I can open the view that I've used and see all the data in the view. I can even add, edit, and delete from the view.
Ideas... Thnxs in advance.
Additional Info. I've added a "View" from "Container Controls" and used the same data source and the same view and it also works in the browser.
The error being printed is:
javax.faces.el.PropertyNotFoundException: Error getting property 'CompanyName' from bean of type lotus.domino.local.View

This was already answered in the comments, but I want to write a better answer.
The problem in this case is that a view data source is being used for editing a document. Directly, this is not a possibility, though there are a few great ways to get around this. The first way, and my favorite, is to use an inline form. I think the Extension Library Demo database offers a few great examples of how to go about doing this. One way is to use a tooltip dialog. Another way is an inline form. A repeater is used and for every row in the view, a hidden panel can be made which contains the document data source and all field which are required to be changeable. By clicking on a button or link, the panel is made visible. This is my favorite variant because it is simple, quick, and generally looks great.
Another way to go about this is to have a view data source only, but use scripts to retrieve the document and set the values in the background and then save and release. It all depends on what you are trying to achieve.
My main recommendation is to look at the ExtLib demo and take a look at what they are doing there.
I'm trying to develop my first module in Orchard and stuck with the following problem.
I have Box content type that contain Books. What I want to achieve is to allow user to add books from box edit screen in admin. The process is the following:
User selects a Box in admin and click edit.
In edit screen a list of books is displayed with buttons "Edit", "Delete" and "Add Book"
The user clicks "Add Book" button and add book screen appears.
The user enters required metadata and clicks "Save"
The user is redirected back to Box edit screen with new book added to the list.
I'm looking for advise on what is the best way to implement this.
There are several ways to do that, most of which don't require building a module.
You could use the updated list feature in the new Orchard 1.8. That does pretty much exactly what you describe.
You could use taxonomies, where the boxes are terms (terms have their own content type that you can extend). The workflow is kinda backwards with this, where you put books in boxes rather than picking from the box which books belong.
You could use a content picker field configured for multiple items, and constrained to the book content type.
You could build your own module, with a relationship between your types, as explained here: http://docs.orchardproject.net/Documentation/Creating-1-n-and-n-n-relations but except if this is a pure learning experience, there's little reason to go for that one, as the other three above are so much simpler, and don't require any coding.
I have a simple ContactEditPanel which contains a form and a number of textfields. Up until now I included an AjaxSubmitLink in this panel which, if the form content is valid, saves/updates the Contact instance contained in the Panel model. So far so simple. However now I'd like to remove the link in order that I may, depending on the context in which I use the ContactEditPanel, place the submit link at different levels of my overall component hierarchy. For instance in one context I'd like to use to flip between ContactEditPanel and ContactViewPanel with a bar of actions above the current view (edit | save , cancel). Another context would be to use ContactEditPanel in a standalone way (maybe part of a multi-step process) with just a save link below.
I was contemplating refactoring my ContactEditPanel to extends FormComponentPanel rather than Panel as described here but I'm not sure whether this is the right approach and I'm having trouble wrapping my head around this.
Any help would be most appreciated!
Many Thanks,
A
Your using the panel like a FormComponent so extend FormComponentPanel, it will allow you to keep all the validation you write contained to the component and also allow you to reuse it as you wish.
Just think of it as you've created a new FormComponent, like a TextField or DropDownChoice.
I need to be able to adjust the alignment of an image in an "Enhanced Rich Text Field" in an announcements list in MOSS 2007. However, the default content editor in the edit form for the list doesn't provide a way to do that. What's the fastest way for me to make sure users can align images? My first thought was to customize the DispForm.aspx and EditForm.aspx pages, but they just have the ListForm web part in the content region and as far as I know, you can't customize the ListForm web part from the designer.
You can't customize the LisForm web part, but you can add a "custom list form" to create a custom edit form. Maybe you haven't seen this article: http://weblogs.asp.net/jan/archive/2006/11/06/Custom-Edit-Forms-for-SharePoint-2007-Lists.aspx
Then you could do some javascript hackery to insert your own button which then calls something similar to existing RTE_InsertImage function to call a pop-up window and do whatever you need (you'll find this function in 12\template\layouts\1033\form.js)
I fail to see (or understand) your issue. I created a new announcements list, created a new item, inserted an image, aligned it to the right, viewed the item and it worked.
Then I proceeded to create a new custom column, choose multiple lines,enhanced rich text field, edited my list item, added an image, centered it, viewed and it was also working.
The only thing I noticed is that the "rich" control does not appears on non-IE browsers.
