Hi,
First you have to create the tree data (see getTreeData() method from
the examples) passing an extra parameter to the TreeNodeBase
constructor, in order to give each node an identifier (I have given
the page to navigate to, for example).
Then, indicate in the action of the commandLink component the following:
<f:facet name="document">
<x:panelGroup>
<x:commandLink immediate="true"
action="#{myBean.menuAction}">
<h:graphicImage value="images/document.png"
border="0" />
<x:outputText value="#{node.description}" />
<f:param name="action"
value="#{node.identifier}" />
</x:commandLink>
</x:panelGroup>
</f:facet>
As you can see, you will have to define a method in your "myBean" bean
in order to be able to execute the action:
public String menuAction()
{
return (String)
FacesContext.getCurrentInstance().getExternalContext()
.getRequestParameterMap().get("action");
}
Notice that you ask for a request parameter named "action", which must
match the name of the param you provided in the JSP view.
In my case, this method returns the identifier of the node clicked,
which is the page to go in the navigation model.
You will only have to provide different logic to that method.
Hope it helps,
Enrique Medina.
