Turning off Comparison with EMF-Compare [message #129057]

Hey out there,

i am currently trying to compare a gmfgen file with one from my
SVN-Repository. (via righ click on the file Compare With --> Latest from
Repository) , But i want to compare it with the standard Text Comparison
of Eclipse.

But it does not matter, whether i set the according Property within the
Preferences-->General-->Content Types. Everytime I start the comparison,
the EMF Compare framework is used instead. I have attached the first
part of the stack-trace at the end of this message

Although I've found some hints within the EMF Compare FAQ how to compare
every file with the text editor (adding all the content Types of EMF
Compare to Text within the Content Type Preference Page) all my efforts
were unsuccesful.

I am currently working with the Eclipse Modeling Tools (includes
Incubating components) Ganymede Package that i have downloaded just some
days before.

Have I missed something, or can anybody give me a hint what to do, so
that my gmfgen files from my local copy and the repository are compared
with the standard comparison editor from Eclipse?

Kind Regards,
Eduard Bauer

The problem with this EMF Compare framework is that it produces an
exception while Comparing:

Hi Ede,

There currently is no way of forcing a text comparison within eclipse
3.4 with EMF Compare installed and unfortunately, we are stuck on this
issue as long as https://bugs.eclipse.org/bugs/show_bug.cgi?id=201116
and https://bugs.eclipse.org/bugs/show_bug.cgi?id=220457 are around.

Yet I wonder... the exception stack trace you provided would imply that
no diff has been produced by the comparison engine and we've never
observed such behavior. I will try and investigate on gmfgen comparison
ASAP.

Cheers
