Re: navigating from tree2

[Roger Lee, NOTiFY]

Thanks for the suggestion.
But I need a listener as I require and action to occur as the user clicks on 
the "Document" TreeNode of the tree2 component.

The ActionListener method is being executed and the value returned is 
"success" but it doesn't cause my <navigation-rule> to execute!

I have tried added a <commandLink action="#{bean.method}" ...> on the 
Document node as well, after the <ActionListener>, but this doesn't get 
executed.

Are you saying that I cannot use the <navigation-rule>  from a tree2 
component?

Regards,
Roger Lee

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.

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.
