> Key: WICKET-3450
> URL: https://issues.apache.org/jira/browse/WICKET-3450
> Project: Wicket
> Issue Type: Sub-task

> Affects Versions: 1.4.11, 1.4.12
> Environment: any wicket 1.4 app
> Reporter: Sergey Plevko

> AbstratTree was originally written againt pure interfaces and not relies on a
> special Class, namely the javax.swing.tree.TreeNode. This breaks all custom
> tree's out there like e.g. the one in the brix project.
> A workaround to this problem I tried was unsuccessful as the problem is that
> many parts of AbstratTree are final and can't be easily overwritten and that
> many other projects epen on Abstrattree like the inmethod grid stuff and much
> more. This means that any special Nodes for trees can't be implemented
> anymore, making this a ultimate stopper for all projects rlying on some
> special nodes. IMHO 2886 should be reverted and then looked upon a differnet
> patch for this solution that doesn't break everything out there.
> Example from default Brxix 1.2.3-SNAPSHOT:
> java.lang.ClassCastException: brix.plugin.menu.editor.MenuTreeNode
> cannot be cast to javax.swing.tree.TreeNode
