Mix layout in a Diagram

Can i use mixed layout in my Diagram, namely for some of the nodes i would like to be layed in a Grid and for some in a Tree. Is it possible ?

Yes, but at this time there is no MultiLayout that you can assign to Diagram.layout. You have to create the layouts and call Layout.doLayout on each one with the desired subsets of nodes and links.

You will probably need to set Layout.arrangementOrigin, although that happens not to have been necessary in the above two samples.

Ok, will try.
