[platform-ui-dev] dynamic content in pop-up menus for objectContribution

[Chris Tilt <chris@xxxxxxxxx>]

My apologies for posting to the dev list, but we've spent considerable 
time looking for the answer.

Is it possible to contribute dynamic content (as in late-binding actions 
and labels) to a cascaded pop-up menu in an objectContribution? I've 
read through the plugin schemas and it seems that objectContributions in 
the context of a pop-up menu extension have a limited set of attributes 
that do not support dynamic actions.

I also tried attaching an actionSet (within actionSet extension) to a 
menu defined within a pop-up extension. But of course, you know that 
didn't work.

The OpenWith class is used often for dynamic menu content, but only in 
viewContribution(s), as far as I see.

The debug team is working on creating Run/Debug in a context menu, which 
will be most useful as an objectContribution. I would greatly appreciate 
any hints.

Cheers, Chris

P.S. Pasted below is non-working attempt that shows the desired feature.
