> I'm facing a serious problem using the cforms tree.
> We added a new functionality: when a user doubleclicks an item, all subitems
> are selected as well. The result is that for every selected subitem an event
> is thrown. The problem, as mentioned in the source code, is that the array
> based constructor of the TreeSelectionEvent is not used. (Besides some other
> minor changes).
> I have adapted the org.apache.cocoon.forms.formmodel.tree.Tree class and it
> works fine. But we'll face a problem after updating, so please tell me how i
> could contribute my code.
