java.lang.IllegalStateException: Cannot modify,resource set without a write transaction [message #236209]

Hi

I'm using a joint EMF-GMF editor as described in the GMF book.
One of its features is linking my DSL to a .uml model so that UML
classes may be loaded and associated with my DSL artefacts .

I see this error occasionally on OS X. I notice that it is similar to
an old GMF Windows bug which claims to be fixed. I get similar symptoms
to this bug

https://bugs.eclipse.org/bugs/show_bug.cgi?id=189587 (Fixed)

My diag file will not open on Eclipse restart, however my EMF editor
still works, the workaround seems to be delete the last edit before the
error message is seen and saving. Then I can open the GMF diag.

Is it possibly the same bug?

regards
Steve

Can you please post full stack trace from this exception here (one you can
see not one from the bugzilla ;-))?

Hi Alex

I was following the process for combining EMF-GMF editors and I
made an error in not calling the newly created multi tabbed editor
so I had a diag editor and emf editor editing the same file. I was
then loading an unclean uml model and associating classes from it
to my entities. (reason the uml is unclean is that it's a fragment
of a large model that was auto-migrated from uml 1.4)

I have since spotted the mistake and am using the tabbed editor and
so far I haven't seen this error again. I'll let you know if it comes
back

I have an older instance of the plugin pre-fix that will generate this
error that I could send a stack trace from if you like?

thanks
Steve

I suppose this error was caused by the reasons listed above.. Let's wait
till it shows up in new code base.
