[jira] Updated: (TOMAHAWK-671) Tree2 fails with NumberFormat

[ http://issues.apache.org/jira/browse/TOMAHAWK-671?page=all ]
Stan Laufik updated TOMAHAWK-671:
---------------------------------
Status: Patch Available (was: Open)
> Tree2 fails with NumberFormat Exception or Null Pointer Exception when ExpandAll button is placed in the same form as Tree2 using RI
> ------------------------------------------------------------------------------------------------------------------------------------
>
> Key: TOMAHAWK-671
> URL: http://issues.apache.org/jira/browse/TOMAHAWK-671
> Project: MyFaces Tomahawk
> Issue Type: Bug
> Components: Tree2
> Affects Versions: 1.1.5-SNAPSHOT
> Environment: WindowsXP, SUN JSF RI 1.1.02, Tomahawk 1.1.5
> Reporter: Stan Laufik
> Attachments: UITreeData.patch
>
>
> 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.
