[e4-dev] Inspired by ESE I get an NPE

[Thomas Kratz <eiswind@xxxxxxxxxxxxxx>]

Hi all I'm just getting started. I got the M3 build and try to run my
3.6 based app on the compat layer.
I added the e4xmi to get started and now I get an NPE (see below)

I didn't make it work to dive into the sources of the e4 bundles (they
are nout found in any way when I click through the stack in debug
mode) so its really nearly impossible to see what this exception comes
from. I thought i'd have a menu without id set but after setting ids
on them it still appears.

Can you give me a hint how to make e4 display the e4 sources when debugging ?

Regards Thomas
