Roger Lee,
if you use <commandLink action="#{bean.method}" ...>
and you have a
<snip>
public String method(){
return ("foo");
}
</snip>
that will help to navigate (be carefull with immediate="true";
my tree.jsp has no immediate for commandLinks that use faces-config.xml
for navigation)
I use actionListener for other things.
Imagine a form that has lot's of opional fields
but only some mandatory fields.
By standard you could show only the mandatory fields
and provide a link "Show complete form". There a actionListener
fits fine in (IMHO).
Below there is a simple example on that.
(a <h:form/> and two actionListener-methods)
HTH,
Matthias

<h:form>
<h:panelGrid columns="2">
<h:outputText value="Vorname"/>

Michael,
The return value was declared outside as;
public class LoanSelectionTreeActionListener {
public String nodeDescription = null;
public LoanSelectionTreeActionListener() {
}
public String selectLoan(ActionEvent actionEvent) throws
AbortProcessingException {
etc etc.
Changed it as suggested, but still fails to forward to
LoanEnquirySummary.jsp
I had this working in WebGalileo using similar technique.
Thanks for your suggestions.

Subject: AW: navigating from tree2
I thing you lost the return value.
Use:
public String selectLoan(ActionEvent actionEvent) throws
AbortProcessingException {
...
return isTreeNodeSelected();
}

Betreff: navigating from tree2
My ActionListener in a tree2 component calls a backing class and gets
the Description from the Tree Node.
LoanSelectionTree.jsp
<x:commandLink immediate="true" styleClass="document"
actionListener="#{loanSelectionTreeActionListener.selectLoan}" >
I then call a method in this Backing Class which returns "success".
public void selectLoan(ActionEvent actionEvent) throws
AbortProcessingException {
//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();
System.out.println(">>>>> LoanSelectionTreeActionListener
selectLoan node.getDescription = " + node.getDescription());
// To force return of "Success"
isTreeNodeSelected();
}
public String getNodeDescription() {
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;
}
}
in my Faces-Config I have;
<navigation-rule>
<from-view-id>/LoanSelectionTree.jsp</from-view-id>
<navigation-case>
<from-action>#{loanSelectionTreeActionListener.selectLoan}</from-action>
<from-outcome>success</from-outcome>
<to-view-id>/LoanEnquirySummary.jsp</to-view-id>
</navigation-case>
</navigation-rule>
I have also tried it with;
<from-action>#{loanSelectionTreeActionListener.isTreeNodeSelected}</from-action>
Either way it does not navigate to my "LoanEnquirySummary.jsp"
No errors thrown. Any suggestions?
Many thanks.
Roger Lee
