[jQuery] async treeview - still have problems re-initializing the tree

[rolfsf]

We're still having problems implementing a 'refresh' button for a
treeview tree. We need to be able to re-initialize the tree, clearing
out the current version completely, and reloading with data fresh from
the server.

we're clearing out the current tree with:
$('#openExistingTree').empty();

and then re-initializing with
$('#openExistingTree').treeview({ url:
"CalcBldrOpenExisting.ashx" });

Each time we hit 'refresh', we're getting a duplicate set of 'hitarea'
divs

The initial json returned is:
"[{'text': 'Private Drafts','id': 3, 'hasChildren': true},{'text':
'Shared Drafts','id': 4, 'hasChildren': true},{'text': 'Published
Calculations','id': 5, 'hasChildren': true}]"

Any help would be appreciated. I realize my previous posts came out a
bit unreadable...

thanks
