Enable delete on figures in GEF [message #57464]

I am trying to enable the "DEL" key to delete the selected figure in a
GEF application. I have looked the logic example but I was not able to
figure it out.

I have installed a COMPONENT_ROLE edit policy that provides the delete
command, and I also added the delete key in the keyHandler in the editor
as in the logic example, but the delete in the edit menu stays
deactivated and the del key does nothing. No requests or getCommand get
called on my EditPart.

I am probably a little confused and I can't figure out what the magic is
in Logic that makes the menu be activated.

PS: GEF is great. Thanks!

I found out the problem: I was overriding init in GraphicalEditor
without calling the super.init() method. This failed to register the
proper hooks with the editor. The examples on wiky web also do this. I
thik they should be corrected.
