After having enjoyed the MINT enhancements without problems, I experience NPEs whenever I attempt to 'customize EMF-generated method' from the outline's context menu.

color codes still work on manually customized methods.

I am using this version:

Eclipse Modeling Framework Technologies (EMFT) - Mint Runtime (Incubation)
Version: 0.9.0.v201006142335
Build id: 201006142335

on this platform:

Eclipse Platform

Version: 3.6.0.v20100602-9gF78GpqFt6trOGhL60z0oEx3fz-JKNwxPY
Build id: I20100608-0911


What can / should I do to fix this problem (reinstall the plugin maybe?)

thanks
/stefan

Stefan,

Please share the stack trace. Probably it's a bug that you should
report. Does it work within the source view?

Hi Ed

No, it does not work in the source view (it actually never did, even when the outline view did).

I tried to debug the error, but it seems I did not get the source code even though I thought to have obtained all source for modeling bundles.


Anyway, here is the stacktrace:

Paste stack traces into this console and follow hyperlinks to source code.

Stefan, could you please share the source file that exhibits the issue?
A bugzilla would be the ideal means. From the stack trace it appears
that there is an unguarded invocation on a null Javadoc reference, but
the action shouldn't even be enabled in this case. A way to reproduce
would be very helpful. Thanks.

--Peter
