Problems with togglepanel

[atulkc]

Hi All,

In our application we are using toggle panel to show/hide data tables. What we are seeing every now and then (not consistently reproducible) is that we get 'Facet not found' exception. I am not really sure what exactly is causing this issue. Below given is the code snippet:

<rich:togglePanel switchType="client" stateOrder="open, closed">
 <f:facet name="closed">
 <h:panelGrid columns="1" border="0">
 <h:panelGrid columns="2" cellspacing="1" border="0">
 <rich:toggleControl switchToState="open">
 <!-- we are actually using h:graphicImage here but for sake of simplicity I am putting outputText here -->
 <h:outputText value="+" />
 </rich:toggleControl>
 <h:outputText value="Summary" />
 </h:panelGrid>
 </h:panelGrid>
 </f:facet>
 <f:facet name="open">
 <h:panelGrid columns="1" border="0">
 <h:panelGrid columns="2" cellspacing="1" border="0">
 <rich:toggleControl switchToState="closed">
 <h:outputText value="-" />
 </rich:toggleControl>
 <h:outputText value="Summary" />
 </h:panelGrid>
 </h:panelGrid>
 <!-- multiple data tables showing some data -->
 ...
 ...
 </f:facet>
</rich:togglePanel>

<rich:panel id="dataList">
 <a4j:repeat value="#{myBean.data}" var="d">
 <rich:spacer height="5" />
 <rich:togglePanel switchType="client" stateOrder="open, closed">
 <f:facet name="closed">
 <h:panelGrid columns="1" border="0">
 <rich:toggleControl switchToState="open">
 <h:outputText value="+" />
 </rich:toggleControl>
 <h:outputText value="#{d.name}" />
 <!-- data table showing summarized data -->
 ...
 ...
 </h:panelGrid>
 </f:facet>
 <f:facet name="open">
 <h:panelGrid columns="1" border="0">
 <rich:toggleControl switchToState="closed">
 <h:outputText value="-" />
 </rich:toggleControl>
 <h:outputText value="#{d.name}" />
 <!-- some more data tables showing detailed data -->
 ...
 ...
 ...
 </h:panelGrid>
 </f:facet>
 </rich:togglePanel>
 </a4j:repeat>
</rich:panel>

With this code I run in to following exception:

Is togglepanel within a4j:repeat causing this problem? Or is it something else?

My environment is as follows:
JBoss AS: 4.2.3 GA
JBoss Seam: 2.1.1 GA
JBoss RichFaces:3.3.0 GA

Any help/pointers are highly appreciated.

Thanks,
Atul

Hello Atul,

Is f:* prefix correctly defined on the page:

xmlns:f="http://java.sun.com/jsf/core"

?

[atulkc]

Yes, I "f:" prefix is defined on the page. Here is the prefix definitions used on the page:

xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:a4j="http://richfaces.org/a4j"
xmlns:rich="http://richfaces.org/rich"

--Atul

[nbelaevski]

This:

<f:facet name="open">
 <h:panelGrid columns="1" border="0">
 <h:panelGrid columns="2" cellspacing="1" border="0">
 <rich:toggleControl switchToState="closed">
 <h:outputText value="-" />
 </rich:toggleControl>
 <h:outputText value="Summary" />
 </h:panelGrid>
 </h:panelGrid>
 <!-- multiple data tables showing some data -->
 ...
 ...
 </f:facet>

may be the reason. f:facet tag must contain single child only.

[atulkc]

I am sorry, I put the comment outside the panelGrid. f:facet does have only child. Below given is the updated code:

<f:facet name="open">
 <h:panelGrid columns="1" border="0">
 <h:panelGrid columns="2" cellspacing="1" border="0">
 <rich:toggleControl switchToState="closed">
 <h:outputText value="-" />
 </rich:toggleControl>
 <h:outputText value="Summary" />
 </h:panelGrid>
 <!-- multiple data tables showing some data -->
 ...
 ...

 </h:panelGrid>
 </f:facet>

Also, as I had indicated earlier the problem is not consistent. It happens intermittently, no known way of reproducing it.

Can you please post web.xml file and content surrounding toggle panels?

 </f:facet>
<!-- SOME MORE TOGGLE PANELS WITH SAME FACET NAMES (OPEN AND CLOSED) GO HERE -->
</rich:tab>
...
...
...
<!-- multiple such tabs that have more toggle panels again with same facet names -->
</rich:tabPanel>
</h:form>

[nbelaevski]

Can you please try replacing f:facet with a4j:facet? Also are you using the latest Facelets version available?

[atulkc]

I am using facelets version that comes with JBoss Seam. For 2.1.1GA Seam version I checked that Facelets version 1.1.15.B1 is being used.

Let me try changing the f:facets to a4j:facets and see if I can reproduce the issue.

Thanks,
Atul

[atulkc]

No luck! Even with a4j:facet I am hitting this issue. Is there any limit on number of togglepanels (with same facet names) that can be used on a single page?

I am now trying by having unique facet names in each togglepanel that I am using.

--Atul

[nbelaevski]

There should be no limit. BTW, does the problem reproduce for client-side method state saving?

[nimo22]

Try to wrap all the content to a4j:outputPanel !

<f:facet name="open">
<a4j:outputPanel>
 nested childs..

</a4j:outputPanel>
</f:facet name="open">

then it should work!

[nimo22]

by the way, I cannot see any documentation for a4j:facet (is this a secret tag?)

[nbelaevski]

That's because documentation is built around TLD files and a4j:facet is a Facelets-only tag.

[atulkc]

I will try both (Client side state saving and a4j:outputPanel) and post my results.
