Re: Getting Description from tree Node - Code Snippet

["Roger Lee, NOTiFY" <ro...@notify.co.uk>]

Just in case anyone is interested;

import javax.faces.component.UIComponent;
import javax.faces.event.AbortProcessingException;
import javax.faces.event.ActionEvent;

public class LoanSelectionTreeActionListener {

    public LoanSelectionTreeActionListener() {
    }

    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();

        System.out.println("********** LoanSelectionTreeActionListener 
selectLoan node = " + node.getDescription());
    }
}
