Tree component single leaf selection

[Geoff Callender <ge...@gmail.com>]

I'm building an example of selection using T5.3's new Tree component but having some difficulties. 

The example will have a tree on the left, and when you click on a leaf the item is shown on the right in review mode, with a button for Edit and a button for Delete. 

Here are the problems:

- I can't prevent more than one leaf being selected at a time.
- Has anyone succeeded in updating a zone when a leaf is selected.

Ideally, the first one would be solved by a parameter on Tree - a bit like HTML Select's "multiple" attribute - and implemented in tree.js. I don't see an obvious way to extend the functionality in tree.js so I've tried server-side event-handling of NODE_SELECTED and NODE_UNSELECTED. The handlers can alter the selectionModel just fine, ie. clear existing selections and set the latest one; but the alterations aren't reflected in the tree that's on screen.

And that brings me to the second problem - even if I put the tree in a Zone, it appears that the JavaScript ignores the Ajax response so nothing will happen. Does this mean I have to provide a Submit button and do full page refresh?

Thanks,

Geoff
