interactive pieChart and rendered attribute - jsf

In my web application, I'm trying to make a simple page where there is a input, a command button, and one panel and a pieChart (inside panel). The panel starts not rendered (there is a MB and a boolean att "canShowPanel" that starts false). When the user clicks the commandButton, a method is called (actionListener) and canShowPanel is set to true, and the panel is updated. All works (the panel and the pieChart are rendered) BUT, the event (itemSelect) is not fired when the user clicks at pieChart slice. I tested start canShowPanel with true value (i.e. all is showed at begin), and all works including the event.
Summarizing: If the pieChart is not rendered at begin and after is rendered the events are not triggered. That is normal behavior? My code is below, but it can be tested with primefaces demos. Only put pieChart inside a panel (outputPanel, panel...) and make it be rendered after. Useful information: the piechart is populate in MB
PS. Running on PrimeFaces 3.6-SNAPSHOT and Mojarra 2.1.7 (SNAPSHOT 20120206) (well... apache tomcat 7...)

Use PrimeFaces blockUI on navigation

I need an answer to exactly this question posted in 2013 please.
I have a PrimeFaces menuitem with a url attribute that calls an xhtml, that 'defines' content to go into a layoutUnit. When clicked, the entire page doesn't reload, just the layout unit.
How do I display a PrimeFaces Extensions blockUI component when the menuItem is clicked?
I've tried:
<p:menuitem value="Users" url="/users.xhtml" onstart="PF('blockUIWidget').block()" oncomplete="PF('blockUIWidget').unblock()"/>
where the blockUIWidget is:
<pe:blockUI widgetVar="blockUIWidget">
<h:panelGrid columns="2">
<h:graphicImage library="images" name="loading.gif"/>
<h:outputText value="Loading"/>
</h:panelGrid>
Note, this widget works as expected from a commandButton:
<p:commandButton value="Login" action="submit" onstart="PF('blockUIWidget').block()" oncomplete="PF('blockUIWidget').unblock()"/>

Render rich:extendedDataTable

I need a rich:popup that shows a rich:extendedDataTable, and when the user presses a button, the popup should be shown, and the extendedDataTable must be re-rendered, here is the code:
<rich:popupPanel id="popupId" show="false" modal="true">
<h:form>
<rich:extendedDataTable
value="#{bean.list}"
var="item" rows="5" id="table">
<rich:column>
<h:outputLabel value="#{item}" />
</rich:column>
</rich:extendedDataTable>
<a4j:commandButton value="x" immediate="true"
oncomplete="#{rich:component('popupId')}.hide(); return false;"/>
</h:form>
</rich:popupPanel>
<h:form>
<a4j:commandButton value="show"
oncomplete="#{rich:component('popupId')}.show(); return false;"
render="table" immediate="true" />
</h:form>
The first time I press the show it works fine, but when I close the panel with the X button and press again the show button, the extendedDataTable appears empty (It's rendered but appear empty, see image below).
The problem is fixed if I add an empty extendedDataTable before the popup, like this:
<rich:extendedDataTable />
<rich:popupPanel>
...
With rich:dataTable the problem doesn't exits, but I need a extendedDataTable.
And aditional extrange behaviour is when I resize the browser, the data appears.
Platform
RichFaces: 4.2.2.Final
Spring: 3.1.1.RELEASE
Cheers
Use onclick instead of oncomplete. ExtendedDataTable doesn't render properly inside invisible elements (it's a bug) so the popupPanel has to be made visible before the rerendering.
I had kinda the same issue.
I solved it in a not 100% richface correct way:
<a4j:commandButton
value="show"
action="#{actionForm.setShowEditor('true')}"
oncomplete="javascript:location.reload(true)"/>
<a4j:region layout="block" rendered="#{actionForm.showEditor}" id="panelArea">
<rich:popupPanel id="#{popupID}" modal="true" show="true" domElementAttachment="parent">
....
tabel
buttons
....
</rich:popupPanel>
</a4j:region>
The popup is always shown (show="true") inside the a4j:region.
But the a4j:region is only shown if variable to show the popup = true.
The full page refresh was in my case needed because otherwise my ckeditor had some initialisation errors. It should also work if you only rerender the a4j:region after you set the "#{actionForm.setShowEditor('true')}.

Primefaces blockUI to block a DataTable doesn't work when the DataTable is updated via AJAX [duplicate]

I am trying to create a datatable that displays a blockUI whenever it is busy, and I have been mostly successful. It now grays out and shows "Loading..." whenever I click either of two commandButtons, sort the datatable by clicking on a header, or page through the datatable. You can see the code for it below.
The problem is that after I have used one of the commandButtons (which runs an ajax update on the blocked element), subsequent actions do not trigger the blockUI (until I refresh the page). For example:
Load page
Click a datatable header - blockUI appears until table is finished sorting
Click one of the datatable page navigation buttons - blockUI appears until the page is loaded
Click one of the commandButtons - blockUI appears until the button's actionListener has finished
Click a datatable header - table sorts, but blockUI does not appear.
Click one of the datatable page navigation buttons - page loads, but blockUI does not appear
Click one of the commandButtons - actionListener runs and table updates, but blockUI does not appear
Reload the page - everything works properly again
Changing the commandButtons' update="" attribute to ajax="false" causes the sorting/paging to always display the blockUI, but the commandButtons to never display the blockUI.
Any ideas?
<div class="buttonDiv">
<p:commandButton ... update="resultsPanel" id="submitButton" ... />
...
<p:commandButton ... update="resultsPanel" id="resetScenarioButton" ... />
</div>
<p:panel header="Results Grid" id="resultsPanel">
...
<p:dataTable ... id="VAResults" ... >
...
</p:dataTable>
....
</p:panel>
<p:blockUI block="resultsPanel" trigger="submitButton, resetScenarioButton, VAResults">
Loading...
</p:blockUI>
The trigger attribute binds jQuery listeners on the specified elements. However if you update an element the binding gets lost. I don't know if it works, but you could try moving the <p:blockUI inside the resultsPanel. I suspect that when you update the panel the blockUI gets updated too and thus re-binding the listener to the data table.
<p:panel header="Results Grid" id="resultsPanel">
...
<p:dataTable ... id="VAResults" ... >
...
</p:dataTable>
....
<p:blockUI block="resultsPanel" trigger="submitButton, resetScenarioButton, VAResults">
Loading...
</p:blockUI>
</p:panel>
I've had the same problem and kind of simillar scenario:
<p:dataTable>
....
<p:ajax event="rowSelect" update="buttons" global="false" onstart="blockMessageButtons.show();" oncomplete="blockMessageButtons.hide();"/>
</p:dataTable>
<p:outputPanel layout="block" id="buttons">
<!-- content to be blocked -->
</p:outputPanel>
<p:blockUI block="buttons" widgetVar="blockMessageButtons"/>
The problem was that panel buttons was both updated by ajax, and blocked by blockUI. I had to divide it in two:
<p:dataTable>
....
<p:ajax event="rowSelect" update="buttons-content" global="false" onstart="blockMessageButtons.show();" oncomplete="blockMessageButtons.hide();"/>
</p:dataTable>
<p:outputPanel layout="block" id="buttons-container">
<p:outputPanel layout="block" id="buttons-content">
<!-- content to be blocked -->
</p:outputPanel>
</p:outputPanel>
<p:blockUI block="buttons-container" widgetVar="blockMessageButtons"/>
#siebz0r already provided the explanation why blockUI stops working when a component is updated.
I am using a one blockUI element in the template for all other pages and thus don't want to include more blockUI elements.
If the blockUI element is updated as well one does not need to move the blockUI inside the component that will be updated.
Here is an example:
<p:panel id="surroundingPanel">
...
<p:commandButton value="ButtonName" styleClass="blockUi"
action="actionToBeExecuted" update=":surroundingPanel :blockUiBinding" />
</p:panel>
<p:outputPanel id="blockUiBinding">
<p:blockUI block=":elementToBeBlocked" trigger="#(.blockUi)">
Loading ...
</p:blockUI>
</p:outputPanel>
The element blockUiBinding can be located anywhere, as long as it can be updated. It is wrapping the blockUI element, because blockUI generates at least two different divs. So when the wrapping element is updated also the blockUI will be updated.

primefaces panelgrid update from datatable

I am getting "Cannot find component with identifier "contentForm:tabView:form:addressDialogPanel" referenced from "contentForm:tabView:form:addressBookTable" " error. How can I update my panelGrid inside the widget?
<h:form id="form">
<p:dataTable id="addressBookTable">
<p:ajax event="rowSelect" listener="#{addressBookController.onRowSelect}"
update="contentForm:tabView:form:addressDialogPanel" oncomplete="addressDialog.show()" />
</p:dataTable>
<p:dialog id="addressDialogId" widgetVar="addressDialog">
<h:panelGrid id="addressDialogPanel" columns="2" cellpadding="4">
</h:panelGrid>
</p:dialog>
</h:form>
The main problem is that you are giving the wrong client ID of component's. Also p:tabView is a component it is not a form. When you define a h:form, it generates a standart HTML form element. And when you submit the page JSF uses POST to submit your data into backing bean. So nesting them is going to occur lot's of issues that you don't expect. You should seperate forms into sections like sideForm or searchForm or etc.
You should detect the correct client ID of your component when you try to update it. You can do this with your browser's developer settings(press f12 for chrome). Then select component with the magnifier button and give that ID into update property. Just like here:
You should read to learn basics of JSF for example from here

Primefaces dialogbox popup refreshes the background and disapears

I am using primefaces dialogbox for popup purpose. But everytime it gets opened the whole screen get refreshed automatically and the popup disappears.
< p:dialog id="dialog" header="Select different user" styleClass="atf-header" widgetVar="dlg" appendToBody="true">
<ui:include src="searchpopup.xhtml" />
</p:dialog>
<h:panelGroup>
<h:outputLabel value="#{I18N['Create_Ticket_for_other_users']}" styleClass="atf-header" style="width:600px"></h:outputLabel>
</h:panelGroup>
<h:panelGroup id="search_section" layout="block"
styleClass="atf-content-area atf-separarot-botton" style="width:600px">
<h:panelGroup id="input_search_section" >
<h:outputText id="name" value="Siddharth Mishra"
labelStyleClass="atf-label">
</h:outputText>
</h:panelGroup>
<h:panelGroup styleClass="atf-right atf-inline-block">
<p:commandButton id="btn_search" value="select different user"
styleClass="atf-button-search" onclick="dlg.show()">
</p:commandButton>
</h:panelGroup>
</h:panelGroup>
You p:commandButton is AJAX button (which is default in primefaces) which submits whole form. Add type="button" attribute to it so it will be just ordinary button which do some JavaScript (so called push button). Also I don't see where is h:form tag here. As you have appendToBody="true" in you p:dialog be shore that you don't encapsulate p:dialog inside h:form. You should have h:form inside p:dialog if it is necessary, and if it is not move p:dialog outside of h:form.
