Hi,
I have a problem, and I think it has to do with start levels in the
launch configuration I am using when developing.

If I have a dirty editor and exit, I get a question if I want to save.
If I answer ok, the builder kicks in, and then it runs into problems
because some bundle(s) have been deactivated.

How can I figure out which bundles need "auto-start" or some start level
set?

e.g. the stacktrace I am looking at right now was caused by
org.eclipse.xtext.builder.internal.Activator.getDefault() returning null.

Hints how to fix this? It is very annoying when developing.
It seems to be ok in the built product, so I am not in panic :)

Regards

Hi Henrik,

I assume that the issue is caused by the builder where some resource
service providers shall be instantiated?
I think we need to listen to changes in the registered bundles in order
to deregister pending extension. That would probably do the trick.

Sebastian

Not sure, problem is really odd, and I have not seen it earlier. It may
have something to do with some screwed up launch config (me or
eclipse... don't know). I got the problem from lots of different places
- and IMO, those bundles should really be around, or a build would
simply not be possible (not a correct one in any case).

I am just switching over to Juno, and have not yet seen the problem
there - maybe it is just something odd with old workspace...

Will post again if the problem comes back on Juno; I have a suspeicion
that it could be because of build taking some time...
