      Description

      I create a simple static tree with two items at the top level and receive a NullPointerException. The repro is attached.

      Test Case:
      1. In a brand new Controller, put the following:

      TreeElement tree1;

      public TreeElement getTree1()

      { return this.tree1; }

      public void setTree1(TreeElement tree1)

      { this.tree1= tree1; }

      2. In the index.jsp, add this:

      <netui:tree dataSource="pageFlow.tree1" selectionAction="postback" tagId="tree1" >
      <netui:treeItem>Hello.</netui:treeLabel></netui:treeItem>
      <netui:treeItem>Goodbye.</netui:treeItem>
      </netui:tree>

      3. Start the server
      4. Hit this index.jsp in the browser

      Behavior: Exception

      java.lang.NullPointerException
