Hi,

Can anyone help me with the following problem:

I'm trying to merge two models in code:

//START CODE
final ResourceSet resourceSet = new ResourceSetImpl();
final EObject model1 = ModelUtils.load
(new File("C:/uml/phpWithAttributes.uml"), resourceSet);

final EObject model2 = ModelUtils.load
(new File("C:/uml/phpWithAttributes1.uml"), resourceSet);

final MatchModel match = MatchService.doMatch
(model1, model2, Collections.<String, Object> emptyMap());

final DiffModel diff = DiffService.doDiff(match, false);

MergeService.merge(new ArrayList<DiffElement>(diff.getOwnedElements()),
true);
//END CODE

I get the following exception:
org.eclipse.emf.compare.diff.metamodel.impl.DiffModelImpl cannot be cast
to org.eclipse.emf.compare.diff.metamodel.ModelInputSnapshot

I would be grateful for any ideas on how to resolve this issue.

Thank you

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

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 Laurent,

I've lost a couple of hours and it seems that i'm doing something wrong
while generating diagrams. If i use the same code on the diagrams i've
created in Eclipse (by hand i add a couple of classes...) everything
works, but if i load my diagrams it crashes with that DiffModelImpl cannot
be cast to ...

But interestingly even my generated diagrams can be compared from the
Eclipse UI. It will be a looong debugging session.

Thank you for everything

Hi,

I've updated to version 1.0, and now i get the following exception:

java.lang.NullPointerException at
org.eclipse.emf.compare.diff.internal.merge.impl.ModelElemen tChangeLeftTargetMerger.undoInTarget(ModelElementChangeLeftT argetMerger.java:75)at
org.eclipse.emf.compare.diff.merge.service.MergeService.doMe rge(MergeService.java:172)at

org.eclipse.emf.compare.diff.merge.service.MergeService.merg e(MergeService.java:136)

Could this issue be happening due to the fact that both uml models are
using the same external profile file defining all stereotypes.

Thank you

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?

Hi Laurent, thank you for all your help!

I've uploaded the code and the files to:

www.fesb.hr/~jomaras/data/testFiles.rar - one profile, two uml models and
two class diagrams

www.fesb.hr/~jomaras/data/callingCode.java

Thank you

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?

Hi Laurent, thank you for all your help!

I've uploaded the code and the files to:

www.fesb.hr/~jomaras/data/testFiles.rar - one profile, two uml models and
two class diagrams

www.fesb.hr/~jomaras/data/callingCode.java

Thank you
