Not able to get the items in select one menu dynamically using ajax

[harsh4u89]

I am not able to get the items in the selectoneItem dynamically

Here is my code:

<h:outputLabel for="branch">Branch</h:outputLabel>   
<h:selectOneMenu id="branch" value="#{stud.masterBranch}" >
<s:selectItems var="branches" value="#{branchList}" noSelectionLabel="[Please Select]" label="# {branches.name}"/>
<s:convertEntity />
<a4j:support event="onchange" reRender="listofsections" />
</h:selectOneMenu>
                    
                      
                    
<h:outputLabel for="section">Section</h:outputLabel>
<h:selectOneMenu id="section" value="#{stud.masterSection}" >
                          
<s:selectItems id="listofsections" var="sections" value="#{sectionList}" noSelectionLabel="[Please Select]" label="#{sections.section}"/>
                                
<s:convertEntity />
                
</h:selectOneMenu>

When I choose Branch from the dropdown menu. It dont show the corresponding sections of that branch

Is there any error in my code?

On <a4j:support /> tag from Brach you must execute the action responsable for load the corresponding Sections.

Like this:

<a4j:support event="onchange" reRender="listofsections" action="#{yourAction.loadSectionsMethod}"/>
