UITreeData: NullPointerException on expandAll
---------------------------------------------

         Key: TOMAHAWK-413
         URL: http://issues.apache.org/jira/browse/TOMAHAWK-413
     Project: MyFaces Tomahawk
        Type: Bug

  Components: Tree2  
    Versions: 1.1.3-SNAPSHOT    
 Environment: Windows 2003 Server / Tomcat 5.5.16 / JVM 1.5.0_06
    Reporter: Bruno Nogueira de Souza


The method expandAll() of UITreeData is calling "walker.next()" without calling 
setTree() on the walker. This cause a NPE because walker.next() call internally 
tree.setNodeId.
