Thanks for Sean & Matthias for their patience
and help.
Now have my tree2 working as I want. You can click
on the Document node of the tree2 component and it forwards to the next page
with the "Loan Name" stored;
As suggest I have both an ActionListener & Action in the
same component;
<f:facet
name="loan">
<h:panelGroup>
<x:commandLink styleClass="document" actionListener="#{loanSelectionTreeActionListener.processAction}" action="" >
<h:graphicImage value="images/document.png" border="0"/>
<h:outputText value="#{node.description}"/>
<f:param name="docNum" value="#{node.identifier}"/>
</x:commandLink>
</h:panelGroup>
</f:facet>
<h:panelGroup>
<x:commandLink styleClass="document" actionListener="#{loanSelectionTreeActionListener.processAction}" action="" >
<h:graphicImage value="images/document.png" border="0"/>
<h:outputText value="#{node.description}"/>
<f:param name="docNum" value="#{node.identifier}"/>
</x:commandLink>
</h:panelGroup>
</f:facet>
The backing class stores the selected Node and sets
"success" for the forward as defined in the faces.config;
public class LoanSelectionTreeActionListener
implements ActionListener {
public String nodeDescription
= null;
public
LoanSelectionTreeActionListener() {
}
}
public void
processAction(ActionEvent actionEvent) throws AbortProcessingException
{
System.out.println(">>>>> LoanSelectionTreeActionListener selectLoan");
System.out.println(">>>>> LoanSelectionTreeActionListener selectLoan");
UIComponent component = actionEvent.getComponent();
UIComponent parent = component.getParent().getParent();
HtmlTree tree = (HtmlTree) parent;
TreeNode node = tree.getNode();
nodeDescription = node.getDescription();
TreeNode node = tree.getNode();
nodeDescription = node.getDescription();
System.out.println(">>>>> LoanSelectionTreeActionListener
selectLoan node.getDescription = " +
node.getDescription());
}
}
public String
getNodeDescription() {
return (nodeDescription);
}
return (nodeDescription);
}
public String
isTreeNodeSelected() {
if
(nodeDescription != null)
{
System.out.println(">>>>> LoanSelectionTreeActionListener isTreeNodeSelected = " + FortyTwoObjectsConstants.SUCCESS_OUTCOME);
return FortyTwoObjectsConstants.SUCCESS_OUTCOME;
}
else {
System.out.println(">>>>> LoanSelectionTreeActionListener isTreeNodeSelected = " + FortyTwoObjectsConstants.ERROR_OUTCOME);
return FortyTwoObjectsConstants.ERROR_OUTCOME;
}
}
System.out.println(">>>>> LoanSelectionTreeActionListener isTreeNodeSelected = " + FortyTwoObjectsConstants.SUCCESS_OUTCOME);
return FortyTwoObjectsConstants.SUCCESS_OUTCOME;
}
else {
System.out.println(">>>>> LoanSelectionTreeActionListener isTreeNodeSelected = " + FortyTwoObjectsConstants.ERROR_OUTCOME);
return FortyTwoObjectsConstants.ERROR_OUTCOME;
}
}
}

Subject: Re: navigating from
tree2
selected you need:
actionListener="#{t.setNodeSelected}"
That is the only way you can do this (for now.) Of course, you could
always extend HtmlTree to do it differently. Also, we could consider
modifying tree2 if there is a compelling argument to do so.
As for navigation, you need an action *method* as Matthias has shown.
AFAIK its perfectly acceptable to have both an actionListener and
action (method) attribute for the same component. If you need to have
your own actionListener in addition to the one required for
maintaining node selection, then you should use the <f:actionListener>
tag to do so.
