I have a form with a PrimeFaces selectOneMenu which, when the user selects an option, I want to refresh a DataTable in the same form with different data. When I select an option I get a Javascript popup that says "malformedXML: During update: outerTab:j_idt185 not found" with no DataTable refresh and on inspecting the source I see an invisible iframe at the bottom of the page with id="JSFFrameId" that contains an element <partial-response> that in turn contains an element <update id="outerTab:j_idt185" ...> and this contains an element <![CDATA[<div id="outerTab:j_idt185" class="ui-messages ui-widget" aria-live="polite"></div>]]>. I think this references my <messages> tag, but nothing in the backing bean creates a message, and I do see an element in the page source <div id="outerTab:facilitatorTestsForm:j_idt113" class="ui-messages ui-widget" aria-live="polite"></div> where the messages should be, so the messages tag is indeed rendered. I can find no element with an ID containing "j_idt185" and apparently neither can some Javascript.
The "outerTab" in the IDs is a PrimeFaces TabView that contains all this stuff.
A page refresh causes the update to happen and the DataTable shows the correct data for the selected SelectOneMenu option.
I have found several posts by balusC where some element that is updated by an ajax call has a rendered value that makes it not render and therefore unable to be found when the update is called for. The target of my update (the DataTable) has no rendered attribute and is visible all the time, so this is a different problem. Other posts speak to a bug in earlier versions of PrimeFaces (I am using 6.1). I cannot figure out why this error occurs.
#Kukeltje kindly pointed me to several posts showing that using an encoding type of multipart/form-data in a file-upload component or a form submit can cause this problem but my page has neither of these.
Here is an excerpt of my page:
<div align="center">
<h:form id="facilitatorTestsForm">
<p:messages for="testBeanMessages" showSummary="true" showDetail="true" globalOnly="true" escape="false" autoUpdate="true" />

<f:ajax update="facilitatorTests" />

</p:column>

I have tried different targets for the selectOneMenu update attribute and it does not change the behavior so I believe it is correct.
Primefaces 6.1
Mojarra JSF API & IMPL 2.2.4
EL 3.0.0
Tomcat 7
Is this a JSF bug? Thanks for any help you can offer.
Found the solution. Thanks to #Kukeltje for staying with me through this even if he did downvote my question for not having enough info :)
It comes back to #BalusC's posts about not rendering the target of an ajax update. In this case I had several PrimeFaces TabView tabs containing <p:messages> tags with autoUpdate="true", and the tabs are shown/hidden depending on the role of the user. When I removed autoUpdate="true" from these messages tags the problem went away. Apparently every time I did an ajax post, even if I had partial submit limited to rendered subelements of the current visible tab, autoUpdate causes JSF to try to update the messages tags in the unrendered tabs and of course they cannot be found.
The way I found this was to put id attributes EVERYWHERE, on every element in my forms. Then the Javascript error pointed me to a named (id'd) element, rather than one with an automatically assigned ID that I could not trace, and when I saw "autoUpdate" the light bulb came on. Moral: put ids on EVERYTHING.
I hope this helps someone with the same symptom to look for autoUpdate everywhere.
And #Kukeltje you were right that my post had inadequate information - without the enclosing tab tags with their rendered attributes you could not have seen the problem. Since they were in another template that ui:includes the forms I did not think they were relevant. Wrongo!

I have a strange behaviour in my code that for some reason I'm unable to solve.
I'm using PF4 and mojarra 2.1.28 running on jboss eap 6.4.
Here's the code
<p:column>
<f:facet name="header">
<p:selectBooleanCheckbox id="checkAll" value="#{backingBean.allowAll}">
<p:ajax listener="#{backingBean.confirmAllowAlla}" process="tablaDoc" update="tablaDoc :form1:facesMessages" onstart="mask();" oncomplete="unmask();" />
</p:selectBooleanCheckbox>
<p:outputLabel for="checkAll" value="Allow all" />
</f:facet>
<p:selectBooleanCheckbox id="checkTipo" value="#{tipoDocumento.allowed}" >
<f:param name="idTipoDocumento" value="#{tipoDocumento.idTipoDocumento}"/>
<f:param name="secuencia" value="#{tipoDocumento.secuencia}"/>
<p:ajax listener="#{backingBean.confirmChange(tipoDocumento)}" process="#this" update="tablaDoc :form1:facesMessages" onstart="mask();" oncomplete="unmask();" />
</p:selectBooleanCheckbox>
</p:column>
Getters and setters exist, backing bean is invoked as it should... apparently everything works but...
when I click in the booleanCheckbox placed in the header all the other checkboxes should be checked.
First time I click internally everything seems to go ok. Model is updated correctly and my datatable is updated accordingly but for the checks. Visually they are not checked (checked="checked" is missing in the output html) but all the expected behaviour is just fine. A button for each row is enabled/disabled and even if I add a column to display the internal value used for the check it renders the expected value.
If I uncheck the main checkbox and check it again, normal behaviour is restored and the checks for each row start rendering ok (checked="checked is in the output html).
I cannot modify my DTOs so I cannot implement SelectableDataModel from PrimeFaces.
Any ideas?
I have a form in my page which has a panel grid inside of it, to show different info. One of the first rows is a breadcrum that shows a tail of selected items at a current moment. I want to define an ajax event for selecting an item and updating that breadcrum (and other components of my page as well). The problem is that I get a "Unable to attach to non-ClientBehaviorHolder parent" error. I searched that this is because PanelGrid Columns (which is the parent component of that breadcrum) doesn't support ajax events, the suggestion was to implement a Data Table, the problem is that i have lots of different components such as Menus, SelectOneMenu, Command Buttons, Graphic Images, etc. that wont render in a DataTable. Is there a way to do this? Here's part of my code as a sample...
<h:form id="catPage">
<p:panelGrid style="width: 100%; margin:auto; text-align: center;">
<!-- Breadcrum of current caregory -->
<p:row>
<p:column colspan="4">
<p:breadCrumb id="breadcrumcat" model="#{categoryBean.dislpayBreadCrumb()}">
<p:ajax event="itemSelect" listener="#{categoryBean.selectCatListener}" update="breadcrumcat" />
</p:breadCrumb>
</p:column>
</p:row>
<!-- More code... -->
</p:panelGrid>
</h:form>
I'm using JSF with PrimeFaces to make an application as an assignment for college. I'm struggling to get something working. I'm using PrimeFaces and I have a tabview which contains 5 tabs. In one of those tabs I have a dataTable which has several rows and columns. This all works fine, but the problem is that I want to submit the form without rerendering the (entire page). The thing is, every column in the dataTable has a selectBooleanCheckbox, and when that checkbox is selected, a button should disappear. If it's unselected the button should appear. This works fine with onchange="this.form.submit()" or onclick="this.form.submit()" but it refreshes the entire application, and it causes the first tab to be selected, rather than the one I was at. So I'm looking for a solution to be able to submit and re-render some stuff without refreshing the entire program. This is my code:
<body>
<h:form id="customerForm">
<p:dataTable id="customerlist" var="c" value="#{customerBean.customerList}">
<p:column>
<f:facet name="header">Select</f:facet>
<center>
<p:selectBooleanCheckbox value="#{c.selected}" onchange="this.form.submit()"/>
</center>
</p:column>
</p:dataTable>
<h:commandButton id="testtest" value="test" rendered="#{customerBean.numberSelected() == 0}"/>
</h:form>
</body>
I removed most of the columns for the sake of simplicity. What is the solution to this? I've tried using ajax, but that didn't work
<p:selectBooleanCheckbox value="#{c.selected}">
<f:ajax event="click" execute="#form" render="#none"/>
</p:selectBooleanCheckbox>
Do you really need to submit the whole form? If it's enough that the view is being rerenderd try just to update the form. For that you can use the primefaces ajax event.
<p:selectBooleanCheckbox value="#{c.selected}">
<p:ajax update="#form"/>
</p:selectBooleanCheckbox>
If this does not work, please tell us what "..ajax, didn't work" exactly mean. Is there any POST Request submitted? Is any Action/Setter called?
I know that this question may be similar to this one but I didn't understand the answer at all.
I am using a full page layout, in the left layout I have some nested accordion panels, tabs and command links. I want this links to update center layout content form.
Left Layout:
<h:form>
<p:accordionPanel>
<p:tab title="Parent Tab">
<p:accordionPanel>
<p:tab title="Child Tab">
<p:commandLink value="link" update=":contentform" />
</p:tab>
</p:accordionPanel>
</p:tab>
</p:accordionPanel>
</h:form>
Center Layout:
<h:form id="contentform">
<ui:include src="#{layoutUI.viewId}" />
</h:form>
And a simple explanation will help cause the similar question lacks in that :(
The proper use of the built in Ajax functionality of the p:commandLink component is to specify that the link will invoke an Ajax call with the ajax attribute.
<p:commandLink value="link" ajax="true" update=":contentform" />
Using the : in front will signify that you are looking for the ID of a component on the ViewRoot rather than its direct Naming Container so this is correct. The only thing missing is the ajax attribute.
I'm using jQuery's .load function to load one JSF page into another.
This works really well until the loaded JSF page uses some AJAX functionality. When this happens, the parent JSF page's AJAX stops working. In fact, after the two pages are combined whichever page has its AJAX called next is the one that continues to work. The other page stops working. If I use the parent page first, the child breaks. If I use the child first, the parent breaks.
Am I doing something wrong? I'm guessing JSF isn't designed for this sort of behaviour and that's fine but then how do I go about doing what I want?
Basically, we have a report page. When the user clicks the link to a report we would like the report to load dynamically into the existing page. That way, the user doesn't experience a page refresh. It's a pretty slick behaviour BUT obviously isn't ideal due to the pages breaking.
I suppose I could do this with a page that contains every report in an outputpanel and then determine which one is rendered based on a value in the backing bean but I can see lots of occasions where I'd like to be able to "inject" one page into another (for dynamic dialogs for instance) and it would suck to have to keep everything in one giant template.
Has anyone else come across this sort of problem? How did you solve it?
Do not use jQuery.load(). It does not take JSF view state into account at all, so all forms will fail to work. Rather make use of <f:ajax> and rendered attribute instead. Here's a basic example:
<h:form id="list">
<h:dataTable value="#{bean.reports}" var="report">
<h:column>#{report.name}</h:column>
<h:column>
<h:commandLink value="Edit" action="#{bean.edit(report)}">
<f:ajax render=":edit" />
</h:commandLink>
</h:column>
</h:dataTable>
</h:form>
<h:form id="edit">
<h:panelGrid columns="3" rendered="#{not empty bean.report}">
<h:outputLabel for="name" value="Name" />
<h:inputText id="name" value="#{bean.report.name}" required="true" />
<h:message for="name" />
...
<h:panelGroup />
<h:commandButton value="save" action="#{bean.save}" />
<h:messages globalOnly="true" layout="table" />
</h:panelGrid>
</h:form>
You can if necessary split off the content into an <ui:include>.
