i will appreciate anyone that can help me look into this problem. I think I
lack the knowledge on proper implementation on ListTree.
I had surfed the net, I couldn't find something that could be of help.
Please, could anyone help me out.

Subject: Fwd: Question on LinkTree implementation
To: users@wicket.apache.org
I found out that if no node is added to the node1, The onclick method works
as supposed.
But if I try to add one sub-node to it, I begin to have the same type of
error as below.
I am sure there is a problem somewhere that I have not been able to trace (I
am a new to wicket framework). Could anyoen help me out.
Thanks

Subject: Question on LinkTree implementation
To: users@wicket.apache.org
hi all,
I am having problems in implementing LinkTree in my page.
I use to get the component not found exception (
WicketMessage: close tag not found for tag: <ul id="node11"
wicket:id="node1">. Component: [MarkupContainer [Component id = node1]]
Root cause:
org.apache.wicket.markup.MarkupException: close tag not found for tag: <ul
id="node11" wicket:id="node1">. Component: [MarkupContainer [Component id =
node1]]
