I'm seeing a strange behaviour with Primefaces (4.0) related to Panels whose collapsed-attributes are bound to a property in a backing bean. Updating the state works fine so the panel collapses/expands correctly when the value of the backing bean changes.
The problem is: I have some p:Dialogs that can be opened to enter some additional/optional information. After closing the dialog, the panel fails to expand/collapse when changing the value. Strangely, other attributes bound to the same property get updated like before.
Example:
XHTML of two panels whose collapsed Attribute is bound to a property. Note that the disabled-attribute of the checkboxes are bound to the same property and still get updated after the dialog is closed.
<p:panel id="panel1" style="width:80%;" toggleable="true" collapsed="#{!bean.panel1.enabled}" widgetVar="panel1Var">
<f:facet name="header">
<p:outputLabel value="Panel1"/>
<p:selectBooleanCheckbox id="p1_enabled" style="margin-left:20px;" disabled="#{bean.panel2.enabled}" value="#{bean.panel1.enabled}">
<f:ajax render="panel1 panel2" />
</p:selectBooleanCheckbox>
</f:facet>
<p:panelGrid columns="2" style="width:100%;" columnClasses="input-col1,input-col2">
<!-- omitted -->
</p:panelGrid>
</p:panel>
<p:panel id="panel2" style="width:80%;" toggleable="true" collapsed="#{!bean.panel2.enabled}" widgetVar="panel2Var">
<f:facet name="header">
<p:outputLabel value="Panel2"/>
<p:selectBooleanCheckbox id="p2_enabled" style="margin-left:20px;" disabled="#{bean.panel1.enabled}" value="#{bean.panel2.enabled}">
<f:ajax render="panel1 panel2" />
</p:selectBooleanCheckbox>
</f:facet>
<p:panelGrid columns="2" style="width:100%;" columnClasses="input-col1,input-col2">
<!-- omitted -->
</p:panelGrid>
</p:panel>
XHTML somewhere else on the same page which opens a dialog:
<p:commandLink id="contactbutton" onclick="PF('contactextended').show();">
<h:outputText value="Extended" />
</p:commandLink>
The dialog is configured like this:
<p:dialog widgetVar="contactextended" modal="true" width="600px" height="500px" showEffect="fade" hideEffect="fade" resizable="false" draggable="false">
The backing bean is a straightforward bean with properties and getters/setter which obviously work. Is there a problem in my implementation? Any ideas how to work around this issue?
Thanks in advance!
Fixed this by myself. The solution seems to be to add process="#this"to the commandLink. I am still not sure what the underlying problem is/was, but at least it doesn't get triggered anymore.

I am working with javaEE, and for my project i used TreeTable and BlockUI to block this table, but i want to make a button appear even if it is blocked
<p:blockUI block=":form:treeTable" widgetVar="tbd" blocked="#{ManagedBean.condition}" />
<h:form id="form">
<p:treeTable id="treeTable" ... >
<f:facet name="header">
<p:commandButton value="SomeAction" actionListener="#{ManagedBean.someAction}" update=":form"/>
</f:facet>
in my example i want to make my commanbutton appear as available even if i use BlockUI
thantk you
This is not a functional problem but a design problem.
As is, the CommandButton is part of the TreeTable, so the CommandButton must be blocked if the TreeTable is blocked.
For sure Raziels answer will work, but a clean solution would be to move the button out of the TreeTable.
<h:form id="form">
<p:commandButton
value="SomeAction"
actionListener="#{ManagedBean.someAction}"
update=":form"
/>
<p:treeTable
id="treeTable"
...
/>
<p:blockUI
block=":form:treeTable"
widgetVar="tbd"
blocked="#{ManagedBean.condition}"
/>
</h:form>
I already Solved this problem by using z-index:99999 inside a style tag
so your code should be like :
<p:blockUI block=":form:treeTable" widgetVar="tbd" blocked="# {ManagedBean.condition}" />
<h:form id="form">
<p:treeTable id="treeTable" ... >
<f:facet name="header">
<p:commandButton value="SomeAction" style="z-index: 99999" actionListener="#{ManagedBean.someAction}" update=":form"/>
</f:facet>
I have a setup in a view, where I display datatables dynamically. That is happening inside a p:accordion-Element, which is generating the tabs dynamically (and therefore the datatables inside).
The user now has the possibility (well, should have..) to add, edit and remove objects to the datatable and therefore to the object that is represented by the tab.
The add- and edit-functions work via dialogs. After successful adding or editing I want to update the datatable containing the data.
If I update the whole accordion-panel I lose the focus on the current tab which is really bad for the user-experience, especially because the other sub-pages of the project always only update the datatable.
After some googling I found out that I can't generate the IDs of JSF-components dynamically, what would make the whole thing a process of minutes.
I also do not have any index I could use to "cheat" and save in my backing-bean when I open the dialog.
I also found out that I could work-around this issue by using JSTL but this is prohibited due to a limited set of allowed languages.
The current setup looks like this:
<p:accordionPanel id="academicYearAccordionPanel"
value="#{academicYearAndClassController.academicYears}"
var="academicYear" multiple="true" dynamic="true" activeIndex="-1"
style="width:100%;">
<p:tab id="academicYear-#{academicYear.academicYear}" title="Jahrgang - #{academicYear.academicYear}">
<p:outputPanel style="float:right">
<p:commandButton value="Löschen" icon="ui-icon-close"
actionListener="#{academicYearAndClassController.setAcademicYear(academicYear)}"
process="#this"
oncomplete="PF('wConfirmAcademicYearDelete').show();">
</p:commandButton>
</p:outputPanel>
<p:spacer style="height:50px;" />
<p:separator />
<!-- Tabcontent -->
<p:outputPanel>
<p:outputPanel style="float:right">
<p:commandButton value="Hinzufügen" icon="ui-icon-plusthick"
actionListener="#{academicYearAndClassController.setAcademicYear(academicYear)}"
process="#this"
oncomplete="PF('wAddSchoolclassDialog').show();">
</p:commandButton>
</p:outputPanel>
<h:panelGrid columns="2">
<h:outputText
value="Klassen des #{academicYear.academicYear}. Jahrgangs" />
<p:spacer style="height:50px;" />
</h:panelGrid>
<p:dataTable emptyMessage="Keine Klassen vorhanden"
id="schoolclassTable"
var="schoolclass"
selection="#{academicYearAndClassController.schoolclass}"
value="#{academicYearAndClassController.getSchoolclasses(academicYear)}"
selectionMode="single" rowKey="#{schoolclass.name}"
scrollable="true" scrollHeight="500">
<p:column headerText="Name">
<h:outputText value="#{schoolclass.identifier}" />
</p:column>
<p:column headerText="Klassenlehrkraft">
<h:outputText
value="#{schoolclass.teacher.name} (#{schoolclass.teacher.symbol})" />
</p:column>
<p:column headerText="Klassenraum">
<h:outputText
value="#{schoolclass.room.name} (#{schoolclass.room.locationName})" />
</p:column>
</p:dataTable>
</p:outputPanel>
</p:tab>
</p:accordionPanel>
I want to update the element with the ID schoolclassTable. How can I achieve this?
Here is some html I am writing to allow categories to be added using a dialog:
<p:dialog id="newCategoryDlg" header="Add New Category" widgetVar="newCategoryDialog" resizable="false">
<h:form id="newCategoryForm">
<p:panelGrid id="displayNewCategory" columns="2" cellpadding="4" style="margin:0 auto;">
<h:outputText value="Category Name :"></h:outputText>
<p:inputText value="#{categoryController.newCategory.name}"
required="true" requiredMessage="Please Enter a Category ID!" />
<f:facet name="footer">
<p:commandButton value="Submit" update=":form:categoryTable"
oncomplete="newCategoryDialog.hide();"
actionListener="#{categoryController.addCategory}">
<p:resetInput target="displayNewCategory" />
</p:commandButton>
<p:commandButton type="reset" value="Reset"></p:commandButton>
</f:facet>
</p:panelGrid>
</h:form>
</p:dialog>
Now, for whatever reason, "" just doesn't seem to work no matter which widget or identifier I use. All I want is for old input entries to disappear after they have been submitted. What am I doing wrong?
You misunderstood the purpose of <p:resetInput>. This misunderstanding is essentially already answered/explained here: Why does p:resetInput require properties of a managed bean to be set to null first after the form is submitted?
As to your concrete functional requirement of the need to update the dialog's content before opening, just do exactly that in the command button which opens the dialog:
<h:form>
<p:commandButton value="Open dialog" action="#{dialogBean.init}"
process="#this" update=":dialog" oncomplete="w_dialog.open()" />
</h:form>
...
<p:dialog id="dialog" widgetVar="w_dialog" ...>
Note that when the dialog contains fields which needs to be validated, then the <p:resetInput> would be very applicable in the button who's updating and opening the dialog in order to clear out invalid state.

I have some weird issue with datatable selection (most likely i'm doing something wrong).
Idea is simple - datatable with selection and a dialog to edit the records. The problem is that if i use <h:inputText> tag (or <p:inputText>) it appears to be blank, though the object in the backing bean (indicatorBean.indicator.code) contains data. Interestingly if i put <h:outputText> instead of input the data is shown.
here are contents of my body
<!-- language: xml -->
<h:body>
<h:form id="form">
<p:growl id="messages" showDetail="true"/>
<p:dataTable id="indicatorsTable" var="ind"
value="#{indicatorBean.indicators}"
selectionMode="single"
selection="#{indicatorBean.indicator}"
rowKey="#{ind.id}">
<p:column headerText="Name" style="width:125px">
#{ind.name}
</p:column>
<p:column headerText="Code" style="width:125px">
#{ind.code}
</p:column>
<f:facet name="footer">
<p:commandButton id="viewButton" value="View"
icon="ui-icon-search" update=":form:display"
oncomplete="indDialog.show()"/>
</f:facet>
</p:dataTable>
<p:dialog id="dialog" header="Indicator Detail"
widgetVar="indDialog" resizable="false"
width="400" showEffect="fade" hideEffect="fade">
<h:panelGrid id="display" columns="2" cellpadding="4">
<h:outputText value="Code:"/>
<!-- PROBLEM IS HERE -->
<h:inputText value="#{indicatorBean.indicator.code}"/>
<h:outputText value="Name:"/>
<h:outputText value="#{indicatorBean.indicator.name}"/>
</h:panelGrid>
<p:commandButton value="Save" onclick="indDialog.hide()"/>
<p:commandButton value="Cancel" onclick="indDialog.hide()"/>
</p:dialog>
</h:form>
</h:body>
Backing bean is nothing other that accessors.
Another thing i spotted is if i replace el expression in <h:inputtext> with a static text (like <h:inputText value="static text"/>), it is shown.
Here are some pictures:
Dialog with inputtext
Dialog with outputtext
Dialog with static text

The problem as you seem to have already figured out is that you are placing the dialog itself inside of a form. This is an issue because of the way the jQuery dialog control works, which is the client side foundation of the Primefaces dialog. Essentially it will move DOM elements associated with the dialog elsewhere, possibly outside of the form that you intend to enclose it.
This problem can be easily solved by putting the dialog outside of the form, and putting a form inside of the dialog body instead.
<p:dialog id="dialogId" ...>
<h:form id="dlgForm">
....
</h:form>
</p:dialog>
In this way when jQuery UI moves the dialog control elsewhere in the DOM, the contents of that DOM, including the form come with it.
i have an issue with nested UI components which is probably a known bug in PrimeFaces and Mojara. However I have no idea how can i solve it.
We have a image gallery with uploader and I want to be able to delete images from the datagrid, so
XHTML:
<h:form enctype="multipart/form-data">
<p:fileUpload fileUploadListener="#{pictureManagementBean.handleFileUpload}"
mode="advanced"
update="gallery messages"
auto="true"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"
/>
<p:growl id="messages" showDetail="true"/>
<p:dataGrid var="item" value="#{pictureManagementBean.pictures}" id="gallery">
<p:panel header="#{item.pictureName}" style="text-align:center">
<h:panelGrid columns="1" style="width:100%">
<p:graphicImage value="#{item.thumbnailDir}" />
<h:outputText value="#{item.createdate.toString()}" />
<p:commandLink value="Delete"
action="#{pictureManagementBean.removePicture(item.idpicture)}" ajax="false"/>
</h:panelGrid>
</p:panel>
</p:dataGrid>
</h:form>
Basically what is not working at the momment - at all - is the commandLink Delete in the DataGrid. The rest is fine.
Is there any walkaround to this? I've tried: columns, ajax, no ajax... nothing works. All i can do is get the button outside the DataGrid. But that's not really what I want.
Any help apprecieated.
[small thing: surprisingly I have used commandLink in DataTable and Columns with no problem! ]
Primefaces 3.4RC1 from maven. (didnt work on 3.3.1 either)
ok so I've found one thing:
inside <p:dataGrid> if I use anything BUT p:columns its not working.
But then the view is terrible... should I just use CSS to fix it?
#Maple_shaft you are so right!
correct code:
<p:dataGrid var="item" value="#{pictureManagementBean.pictures}" id="gallery">
<p:column>
<p:panel header="#{item.pictureName}" style="text-align:center">
<h:panelGrid columns="1" style="width:100%">
<p:graphicImage value="#{item.thumbnailDir}" />
<h:outputText value="#{item.createdate.toString()}" />
<p:commandLink value="Delete"
action="#{pictureManagementBean.removePicture(item.idpicture)}" ajax="false"/>
</h:panelGrid>
</p:panel>
</p:column>
</p:dataGrid>
So just simple column element. I've just places it wrong before. Thanks so much.
Of course backing bean is #ViewScoped!
