Collapsible panel not working

Question

Hi,
I am facing a problem with Collapsible panel provided by tomahawk.
The action method of the command link in the <f:facet> is not invoked.* This method is used for toggling the value of the boolean variable assigned to value attribute of <t:collapsiblePanel> and because this method is not invoked the panel doesnt display the contents
<t:collapsiblePanel id="RequirementInformationPanel" value="#{RgsViewRequirementBB.collapseReqPanel}">
          <f:facet name="header">
               <h:commandLink id="toggle" action="#{RgsViewRequirementBB.renderPanel}" value="#{bundle['rgs.label.requirementRelatedInfo']}" />          </f:facet>
          <h:panelGrid styleClass="panelBorder">
                    <h:panelGrid columns="4" >
                         <h:outputText value="#{bundle['rgs.label.RequirementId']}" style="width : 150px" styleClass="screenLabelBold" />
                         <h:outputText value="#{bundle['rgs.label.RequestId']}" style="width : 150px" styleClass="screenLabelBold" />
                         <h:outputText value="#{bundle['rgs.label.Exop']}" style="width : 150px" styleClass="screenLabelBold" rendered="#{!RgsViewRequirementBB.displayCandidateView && RgsViewRequirementBB.exop=='true'}"/>
                         <h:outputText value="#{bundle['rgsView.RejectedCandidates']}" style="width : 150px" styleClass="screenLabelBold" rendered="#{RgsViewRequirementBB.displayCandidateView}"/>
                    </h:panelGrid>
                    <h:panelGrid columns="4" >
                         <h:outputText value="#{RgsViewRequirementBB.requirementId}" style="width : 150px" id="RequirementId" styleClass="screenLabel"/>
                         <h:outputText value="#{RgsViewRequirementBB.requestId}" style="width : 150px" id="RequestId" styleClass="screenLabel"/>
                         <h:graphicImage rendered="#{!RgsViewRequirementBB.displayCandidateView && RgsViewRequirementBB.exop=='true'}" value="../images/flag1.gif"/>
                         <h:outputLink onclick="rejectedCandidatePopupFromDetailsScreen(this,this.form);return false;" rendered="#{RgsViewRequirementBB.displayCandidateView}" id="RejectedCandidateLink">
                              <h:outputText value="Rejected Candidates" style="width : 150px"/>
                         </h:outputLink>
                    </h:panelGrid>
          </h:panelGrid>
     </t:collapsiblePanel>In the backing bean I am having collapseReqPanel as a boolean variable which is initialized to true along with its getter and setter methods and the renderPanel (action method for command link inside the facet tag of collapsible panel) method is:
public String renderPanel(){
    System.out.println("Inside Render panel");
     collapseReqPanel=!collapseReqPanel;
     return null;
}What is wrong in the above code?

Answer 1

Is your bean request or session scoped? If request scoped, try session scope. If it works and you want to keep it request scoped, you'll have to pass the collapseReqPanel booleanvalue to the next request using h:inputHidden or requestMap so that it retains in the next request.
