Re: [m2e-users] M2E Update Project issue

[Markward Schubert <markward.schubert@xxxxxxxxx>]

Well at least this is a trace :-).

Can you tell me, what versions of m2e and PDE you have in the setup,
with which you can NOT reproduce this?
I would try out then if this occurs still, when I update to these
versions. If we can solve it by moving to a newer version of eclipse
or PDE, this would be even nicer, as there would be no bug to wait
for.

Markward
