Thanks for the reply Jeff.
I am currently trying this but getting a ClassCastException when the
tabChangeListener tag is encountered. Does anyone know where I can find the
source for tomahawk, so I can step through int he debugger? Only bin is
available here: http://www.wmwweb.com/apache/myfaces/

java.lang.ClassCastException: com.site.util.EditUserRecordTabListener
at
org.apache.myfaces.custom.tabbedpane.TabChangeListenerTag.doStartTag(TabChangeListenerTag.java:82)
Here is the code:
package com.site.util;
import javax.faces.context.FacesContext;
import javax.faces.el.ValueBinding;
import javax.faces.event.AbortProcessingException;
import org.apache.myfaces.custom.tabbedpane.TabChangeEvent;
import org.apache.myfaces.custom.tabbedpane.TabChangeListener;
import com.site.actions.EditUserRecordAction;
public class EditUserRecordTabListener implements TabChangeListener {
public void processTabChange(TabChangeEvent event) throws
AbortProcessingException {
int newIndex = event.getNewTabIndex();
int oldIndex = event.getNewTabIndex();
EditUserRecordAction action =
(EditUserRecordAction)getManagedBean("editProfileAction");
action.setSelectedTab(newIndex);
}
public static Object getManagedBean(String ref) {
// Find or create the web-tier data object
// ref like "#{myBean}"
FacesContext context = FacesContext.getCurrentInstance();
ValueBinding binding =
context.getApplication().createValueBinding(ref);
Object result = binding.getValue(context);
return result;
}
}
