I have a tree2 that displays a contest hierarchy. Many of the nodes are
clickable, and when clicked, they are supposed to set a backing bean property
based on a property of the node. The code for it is:
<h:form>
<t:tree2 value="#{tree}" var="node" varNodeToggler="t"
clientSideToggle="true"
showRootNode="false" showNav="false">
<f:facet name="root">
#{node.description}
</f:facet>
<f:facet name="system">
<h:commandLink value="#{system.name}"
action="viewContestSystem">
<af:setActionListener from="#{system}"
to="#{contestSystemBean.current}" />
</h:commandLink>
</f:facet>
</t:tree2>
</h:form>
The problem is, when I click on the link for any of the system nodes I get:
15:47:38,517 ERROR [faces]:253 - Servlet.service() for servlet faces threw
exception
java.lang.IllegalArgumentException: Unable to locate facet with the name: root
