We have just released an updated version of the PMAP demo that is now compatible with Morfik 3.0. This contains a full version of the Tree control.
Please note that this is a first phase of a two step process. The new demo works with Morfik 220.127.116.11 correctly, but the tree control is not a widget yet. In the next phase we will create a widget out of it so that it is easier to use with Morfik 3.
