Tree: NPE on a static tree
--------------------------
Key: BEEHIVE-346
URL: http://issues.apache.org/jira/browse/BEEHIVE-346
Project: Beehive
Type: Bug
Components: NetUI
Versions: V1
Reporter: Karen Stutesman
Assigned to: Daryl Olander
I create a simple static tree with two items with the same parent 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
