How reload LinkTree
Im try to use LinkTree for display database content. If used DefaultTreeModel
as in example, new data not added in tree on page refresh. Its normal. Ok,
im try to use LoadableDetachableModel for tree model. Now, data reload on
refresh, but data reload also on each click on tree nodes, as result, nodes
can't be expanded.
Im need reload data on two cases, on ajax request and on page refresh. How I
can do this.
Thanks and sorry for my english.

Re: How reload LinkTree
Posted by Sven Meier <sv...@meiers.net>.
If you change nodes in your tree model, you have to fire appropriate
change notifications, e.g. with DefaultTreeModel#nodesChanged().
Additionally for Ajax request you must call LinkTree#updateTree() to let
it update its components.
Making this work with dynamic data from a database is no easy task, so
I'd recommend using an alternative implementation:
http://code.google.com/p/wicket-tree
Note that this solution is part of Wicket 6.
