Here is my tree2 code (it is rendered inside a <t:paneltab> component):
<t:panelTab label="Catalogue" >
<h:panelGrid columns="2" border="1" width="100%" cellspacing="3"
columnClasses="columnTree1,columnTree2" >
<h:column >
<t:tree2 id="clientTree" value="#{treeBacker.expandedTreeData}" var="node"
varNodeToggler="t" >
<f:facet name="ajaxDocument2">
<h:panelGroup>
<a4j:commandLink id="a4jLink" styleClass="document"
actionListener="#{treeBacker.nodeClickedAgain}" reRender="a4jGroup">
<t:updateActionListener property="#{treeBacker.clickedNode}"
value="#{node}" />
<h:outputText value="#{node.description}"/>
<f:param name="docNum" value="#{node.identifier}"/>
</a4j:commandLink>
<f:facet name="expand">
<t:graphicImage value="/images/tree/blue-folder-open.gif"
rendered="#{t.nodeExpanded}" border="0"/>
</f:facet>
<f:facet name="collapse">
<t:graphicImage value="/images/tree/blue-folder-closed.png"
rendered="#{!t.nodeExpanded}" border="0"/>
</f:facet>
</h:panelGroup>
</f:facet>
</t:tree2>
</t:panelTab>
TreeBacker.java
public TreeNode myTreeModel(){
//this is where i set the different TreeNodeBase objects.
}
public TreeModel getExpandedTreeData()
{
return new TreeModelBase(myTreeModel());
}
faces-config.xml
<managed-bean>
<managed-bean-name>treeBacker</managed-bean-name>
<managed-bean-class>webui.tree.TreeBacker</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
In my logs, I could see that myTreeModel() method is invoked twice whenever
the tab containing my tree2 is clicked. What could be the possible culprit
for the said behavior?
