Description

When a button that executes HtmlTree.expandAll is put into the same <h:form> then the Tree2 component after clicking on the button Tree2 throws NumberFormat or NullPointer exception (depending on which build of Tomahawk is used).

On our system I have fixed it with teh following code:

package org.apache.myfaces.custom.tree2
class UITreeData

public void broadcast(FacesEvent event) throws AbortProcessingException
{
if (event instanceof FacesEventWrapper)

{ FacesEventWrapper childEvent = (FacesEventWrapper) event; String currNodeId = getNodeId(); setNodeId(childEvent.getNodeId()); FacesEvent nodeEvent = childEvent.getFacesEvent(); nodeEvent.getComponent().broadcast(nodeEvent); setNodeId(currNodeId); return; }

else if(event instanceof ToggleExpandedEvent)
{
ToggleExpandedEvent toggleEvent = (ToggleExpandedEvent) event;

if (toggleEvent.getNodeId() != null && !"null".equals(toggleEvent.getNodeId()))

{ String currentNodeId = getNodeId(); setNodeId(toggleEvent.getNodeId()); toggleExpanded(); setNodeId(currentNodeId); }

}
else

{ super.broadcast(event); return; }

}

The chanegd code first check if the node to be toggledis valid before it performs the toggle.
