$$ajaxid is #none in a partial refresh - xpages

I´m doing a partialrefresh on another div like this:
XSP.partialRefreshGet(idZusatzgeräte , { params: { 'keyValueFortabZusatzgeraete': paramValue}});
When I look into Chrome Network the partial refresh is executed. But there is no response from the request. Furthermore $$ajaxid equals to "#none". I found that if $$ajaxid is #none there will never be a response. Strange thing is that if I execute the partialrefresh from my console in my browser it works just fine.
Does anyone have a clou on how to disable this #none in the ajaxid?

(Yii2) the page that you are looking for used information.....?

my simple view file
<?php
use yii\helpers\Html;
use yii\bootstrap\ActiveForm;
?>
<?php ActiveForm::begin()?>
<?=Html::submitButton('something')?>
<?php ActiveForm::end()?
Clicked the button. After I reload the page and browser shows me
this
So how can I remove this?
This problem happen when you submit data in a form and then refresh the page
Browsers should stop this, or at least prompt if you want to resend the data,
but the best way to prevent this from happening is submit the data .. and manage the submit properly.
In you case your submit repeat the index action because you don't manage proper the action code
(all you're being made does not produce the creation of a new model to be complete so as not prroduce displaying a result.
or any other action ..
your code continues to call the same action that produces post calling for action and so on)
try adding a simple die() or a render for another view
public function actionIndex()
{
if (Yii::$app->request->post('submit')==='my_value') {
echo "Button my_value Clicked";
die(); // or render a proper view
}
return $this->render('index');
}
This is basic browser behavior. Your form is doing a POST request and obviously when you try to refresh it will ask for this. Even if you write a basic html page without yii, you will still have this.

Error messages making queryString disapprear in jsf

I have issue from client end with jsf 1.2 as explained below
I am navigating on click on command button to the url below
test/editProject.jsf?value=123
If any field are missing I am using addErrorMessage('id','string') and returning fail in validation method. The error message is displayed under that component.. I am fine till this..
The problem is the url is displayed as
test/editProject.jsf
Here the value queryString is missing..if the user correct the error and click on save it works fine..it is working as per jsf cycle
Issue
My client is pressing enter on the browser url tab which has the url test/editProject.jsf. I told him to use F5 button to refresh but he didn't agreed.. any idea how to retrieve the query string back on getting error message.
I have used redirect in my project but I think here its not good idea to use..
Please let me known if you any solution for this..
Thanks for help.

#{javascript:viewScope.something} won't update after context.redirectToPage(...)

It is not long ago that I asked this question, which was about updating a property bundle after a csjs-induced full refresh. I solved it with a URL-parameter that lead to a context.redirectToPage.
Now I have an xPage with a jquery-based jqGrid, which receives a string with JSON-data from the viewScope and displays that data in a table. When I edit a record in the grid and hit 'submit' the grid posts a parameter called 'oper' with values like 'edit', 'add', etc., for which I check in the beforePageLoad event of the page and then execute the save method of my managed bean. After this I update the viewScope variable with the new JSON-string and conduct a full refresh in the above mentioned manner which had worked before.
<xp:this.beforePageLoad><![CDATA[#{javascript:
if (bccUser.isAdmin() && param.containsKey('oper') && param.get('oper').toString().length>0) {
bccGridDataHandler.saveGridDoc('RequestDummy','PersonRequestsDummy',param);
}
viewScope.put('jsonString',bccView.getViewColumnValue('PersonRequestsDummyJson',1));
print('jsonString in viewScope: '+viewScope.get('jsonString'));
if (bccUser.isAdmin() && param.containsKey('oper') && param.get('oper').toString().length>0) {
var url = context.getUrl().toSiteRelativeString(context);
if (url.indexOf('?')!=-1) {
url += "&doRefresh=true";
} else {
url += "?doRefresh=true";
}
print("redirecting to: "+url);
context.redirectToPage(url);
}}]]>
In the server console I can see the correct, updated JSON-string from the first print statement, so the save-method was successful and I have up-to-date data in my viewScope. The grid, however, does not show the updated data, neither does my test-div
<xp:text value="#{javascript:viewScope.get('jsonString')}" />
I also tried a partial refresh on the grid and div after updating the viewScope, but the same happened. After a manual refresh of the page everything is fine again. So, what's happening here? I just want to pass a simple string to a control. Am I mistaken again about the xPages-Lifecycle and the order of events?
Thanks in advance. Regards, Sarah
I think you are losing the viewScope value in the redirectToPage. Try with requestScope or sessionScope.
Thanks for all the suggestions, I tried them all out but unfortunately with no luck. The most interesting thing about this was, that when I put a clientside alert statement into the onClientLoad event it would just fire once, when I enter the page, but not after any of the context.redirect or .reload commands.
After all I solved the problem the following way:
I removed the redirect command from the beforePageLoad event and added the following parameter to the submit function of the jqGrid (see documentation here):
afterSubmit: function(response, postdata) {window.location.href=window.location.href;return [true,'',''];}
This works for me (onClientLoad is also triggered again after this), but still I wonder why a page refresh induced from the serverside doesn't do the same thing as a clientside refresh, or isn't able to imitate a clienside refresh.
I am not sure if the beforePageLoad event is the right one, have you considered generating the JSON in beforeRenderResponse?

XPages: execute context.redirectToPage after client side function?

Why does context.redirectToPage behave differently when executed in a view root-event instead of an event handler?
This question came up when I tried to set the language of an xpages application to the language saved in the user profile, once the user is logged in. I use a properties-file with translated strings in a resource bundle, and retrieve the strings like this:
<xp:text value="${langString['WELCOME_TEXT']}" />
When the language is changed and so a different properties-file is loaded, the page needs to be refreshed in order to update those strings. This worked fine when I added a full-refresh event handler to the login button, that executed a server side context.redirectToPage(). No luck with client side refreshes like location.reload or window.location.href=window.location.href (the login-function itself is a client side function though).
But of course the user expects that he is also logged in when he presses the enter key instead of the button after he has entered his credentials. So I added an onkeypress-event to the username and password input fields, and checked for the enter key (if (thisEvent.keyCode==13) dosomething...) before executing the login function.
But now the event handler is called every time a key is pressed and of course I do not want the context.redirectToPage to be executed all the time.
Thus I removed the server side event handlers and changed the login function so that it terminated with a partial refresh of the div containing the whole page:
var p = {"execLogin":"true"}; XSP.partialRefreshPost( '#{id:wholePage}', {params: p} );
The parameter sent via the partial refresh now triggers an event in which our context.redirectToPage is executed:
<xp:this.beforeRenderResponse><![CDATA[#{javascript:if (param.containsKey('execLogin') && param.get('execLogin').toString().equals('true')) {
print("test");
context.redirectToPage(context.getUrl().toSiteRelativeString(context),true);
}}]]></xp:this.beforeRenderResponse>
The page is refreshed and "test" is printed out, but I still see the old language strings. I have to refresh the page manually again to make the new user language take effect.
Any idea how to execute a genuine full refresh this way, or maybe another way to update the strings retrieved from the property bundle?
Thanks in advance. Regards,
Sarah
EDIT
I now have:
<xp:inputText id="cc_login_panel_login_username" styleClass="span2">
<xp:eventHandler event="onkeypress" submit="true" refreshMode="complete">
<xp:this.script><![CDATA[if (thisEvent.keyCode!=13) {
return false;
} else {
doLogin();
return true;
}]]></xp:this.script>
<xp:this.action><![CDATA[#{javascript:context.redirectToPage(context.getUrl().toSiteRelativeString(context));}]]></xp:this.action>
</xp:eventHandler>
Because context.reloadPage() didn't even log me in somehow (strange) I got back to using redirectToPage. The server side event is fired once and at the right time *thumbs up*, but the language properties-bevaviour is still the same.
$ is only set on page load, whereas # is set each time during the partial refresh.
I don't think a partial refresh will work at all though. This will refresh the computed field. However, it will need a full refresh to refresh the part of the XPage that includes the properties file. In other words, you would be refreshing the computed field, but using the same properties file.
I wonder if context.redirectToPage or context.reloadPage is somehow going to the same page but with the cached properties files.
If you're always wanting to come back to the same page, a full refresh instead of partial refresh may be the best option.
I think this has something to do with using the $ parameter. this tells the runtime to retrieve the language file the first time the current page is created in the back-end. When a user does a refresh it is actualy retrieving a saved version of the page you are viewing.
I see you're calling "context.redirectToPage(context.getURL().toSiteRelativeString(context)))" within an xp:this.action tag for the xp:eventHandler.
Try using xp:this.onComplete in place of xp:this.action.
According to the Designer tooltip for the action, the expected return is a string to be passed to the navigation handler. So instead giving the onComplete will execute the redirect command when it's done with the eventHandler group of events.
Thanks for all the helpful answers, in fact all of them did work, the problem turned out to be my misunderstanding of when the properties-file is loaded. It is loaded in an early phase, long before my new language is set to the sessionScope (that sessionScope variable is then used as a part of the name of the properties-file to be loaded, via the VariableResolver).
Now I use a double full refresh to load the new file. When the login function terminates successfully, it executes:
window.location.href = window.location.href + "?doRefresh=true";
And to the view root element I added the following event:
<xp:this.beforeRenderResponse><![CDATA[#{javascript:
if (context.getUrlParameter("doRefresh")!=null&&context.getUrlParameter("doRefresh").equals("true")) {
var url = context.getUrl().toSiteRelativeString(context);
url = url.replace("?doRefresh=true","");
context.redirectToPage(url);}
}]]></xp:this.beforeRenderResponse>
This is not a very sophisticated solution, but at least it works :-)

Seam:token tag not being respected

When I click a command button, and then hit the browser back button to the form and click it again, it submits a second time without throwing the proper exception...
Even stranger, the form id itself is DIFFERENT when I come back, which implies it has regenerated a "valid" form id at some point.
Here's the relevant code: Any ideas?
<h:form id="accountActivationForm">
<s:token/>
<a4j:commandButton id="cancelActivateAccountButton"
action="#{controller[cancelAction]}"
image="/images/button-Cancel-gray.gif"
reRender="#{reRenderList}"
oncomplete="#{onCancelComplete}" />
 
<a4j:commandButton id="activateAccountButton"
action="#{controller[agreeAction]}"
image="/images/button-i-agree-continue.gif"
styleClass="activate-account-button"
reRender="#{reRenderList}"
oncomplete="#{onActivationComplete}"/>
</h:form>
Clarifications:
I inherited this, so I'm trying to change it as little as possible. (It's used in a couple places.)
Each action returns a view, not null. I have confirmed this by stepping through line-by-line.
The reRenderList is empty in my current test-case.
onActivationComplete is also empty.
I'm going to be going template-by-template to see if someone made it with nested forms, because my coworkers have had unrelated problems due to that, so it couldn't hurt to eliminate that as a possible problem.
The s:token is supposed to avoid double/multiple submits by impatiently clicking the submit button multiple times in the same request or by refreshing the non-redirected result in the webbrowser or by resubmitting the cached page in the browser history.
That it works when the client navigates back and forth by browser history just means that the pages with the forms are not cached in client's browser history and are requested as brand new from the server side again. That would indeed return a new token. Check it yourself with a HTTP tracker like the one in Firebug.
