[jira] Resolved: (BEEHIVE-346) Tree: NPE on a static tree when 'accidently' specifying two root nodes

Daryl Olander resolved BEEHIVE-346:
-----------------------------------

      Assign To: Karen Stutesman  (was: Daryl Olander)
     Resolution: Fixed
    Fix Version: V1Beta

The problem was I was calling registerError on the parent of the TreeItem tag and then reportError in the TreeItem.  The result was that the TreeItem didn't have any error state. I removed the call to reportError because the Parent tag does that anyway after processing the body.

> 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
