Hi Josip,
The error message is pretty straightforward. You cast something you
shouldn't be :).
The line that triggered this is not part of what you copy pasted here.
You have somewhere in your code "(ModelInputSnapshot)aVariable", yet
"aVariable" is of type "DiffModel" and DiffModel is not a subclass of
ModelInputSnapshot ... thus cannot be cast to it.
You can take a look at org.eclipse.emf.compare.examples.standalone to
see an example of how to create and save to disk a ModelInputSnapshot (I
believe this is what you're trying to achieve). If you cannot fix this
error, please copy paste here the line that triggers your exception and
the few lines above it, as well as the few first lines of your exception
so that I can see the line numbers.
Cheers,

Hi Laurent, thank you for your response!
Unfortunately, i haven't done any mysterious casting. This is the whole
code.
I'm building a tool to RE php, html and JavaScript into models matching
Connalen's web UML extensions. And these two models (phpWithAttributes.uml
and phpWithAttributes1.uml) are something that my code generates. I'm not
sure but maybe i haven't cleaned up some resources in the model generation
phase - i'll have to check. But my generated models are ok when read from
Eclipse.
The exception is thrown from
MergeService.merge(new ArrayList<DiffElement>(diff.getOwnedElements()),
true);
Thank you for your help

Hi Josip,
This might come from a problem within the merge code then ... Could you
copy paste the whole exception stack trace?

Josip,
Something I didn't realize before but ... ModelInputSnapshot is a class
that doesn't exist anymore, since 0.9M3 if I am not mistaken. moreover,
DefaultMerger.findRightResource() is deprecated in the latest CVS code.
The 0.9 stream is compatible with the same Eclipse versions as the 0.8
was (see http://wiki.eclipse.org/EMF_Compare#Compatibility ). Can you
try with the latest release of EMF Compare or is there a reason why you
didn't update?

Hi Josip,
This exception would mean EMF Compare couldn't find the Resource of your
right model ... Are you using a code as shown in
org.eclipse.emf.compare.examples.standalone.ExampleLauncher or equivalent?
if you are, could you raise a bugzilla with your code and the two models
you compare so that I can try and reproduce?
