adding markers to eugenia based editor after applying evl constraints to emfdiff model [message #527798]

Hello Community,
I am currently working with consistency checking. I am comparing two model of same meta model and getting errors markers in the validation view of the EVL after applying the EVL constraints on the emfdiff model generated after model comparison. I want to attach the evl constraints which i am applying to emf diffmodel with eugenia based editor.
I have the following questions

which exentions should be used to attach the evl constraints for emfdiff model so that i get the errors in the errors view ?
and how can i see the error markers in the eugenia based editor?

is there any other efficient way of solving the above mentioned challenge?

best regards
saad

Hi Saad,

There's no built-in support for this. I guess what you'll have to do is
to find the markers in the diffmodel, resolve the target eObject that
marked diffs refer to, look in the workspace for diagrams that point at
these eObjects and add markers to the respective diagram elements.

Cheers,
Dimitris

Hello Dimitrios,
Thanks for the reply. As a starting point I am trying to work out with "EvlStandaloneExample". I checked out from epsilon svn. I am running the "EvlStandaloneExample.java", but i am getting the following error

java.lang.UnsupportedClassVersionError: Bad version number in .class file
at java.lang.ClassLoader.defineClass1(Native Method)

Am i missing something? or if there is some pre setup i need to consider?

Hi Saad,

This sounds like a Java version problem. Which JRE version are you
using?

Cheers,
Dimitris

Hello Dimitrios,
thanks again for the reply. yes i changed the Jre version and it started working now. I have one more question regarding

models.add(createEmfModel("Model", "models/result.emfdiff", "x", true, true));

when i am trying to load the models both the instance and the meta model, I want to know what should i put in "x", which has to be the meta model for the emfdiff model? any ideas how can i actually load the models before i apply the constraints on results.emfdiff?

best regards
saad

Hi Saad,

The namespace uri of *.emfdiff models is
http://www.eclipse.org/emf/compare/diff/1.1 As you're running this
through a standalone Java application, please make sure that the EMF
diff EPackage is actually in the EPackage registry before trying to load
the model.

Cheers,
Dimitris

Hello Dimitrios,

Thank you again. I used the following code in EvlStandaloneExample.java class to upload the models

@Override
public List<IModel> getModels() throws Exception {
List<IModel> models = new ArrayList<IModel>();

String file=" C:/eclipse-Galileo/eclipse/Sciaml-Test/ie.lero.helloworld.de mo.compare/diffmodel/result.emfdiff ";
models.add(createEmfModelByURI("Model", file, "http://www.eclipse.org/emf/compare/diff/1.1", true, true));
return models;
}

@Override
public String getSource() throws Exception {
return " C:/eclipse-Galileo/eclipse/Sciaml-Test/ie.lero.helloworld.de mo.compare/diffmodel.evl ";
}

where "result.emfdiff" and "diffmodel.evl" are in runtime enviornment. When i run the code using incremental plug-in i get the following error

java.lang.NullPointerException

Hi Saad,

You'll need to add the org.eclipse.emf.compare.diff and
org.eclipse.emf.compare.match plugins to the dependencies of your
project and add these two lines at the beginning of your getModels() method:

EPackage.Registry.INSTANCE.put(DiffPackage.eNS_URI,
DiffPackage.eINSTANCE);

EPackage.Registry.INSTANCE.put(MatchPackage.eNS_URI,
MatchPackage.eINSTANCE);

Cheers,
Dimitris

Hello Dimitrios,
Thanks again for the quick reply. I followed the instructions you mentioned earlier. unfortunately its still not loading the models and i am getting the following errors

Exception in thread "main" java.lang.NullPointerException

I don't know how to proceed from here. I am sending you the project i am working with on your official e mail address. If you get some time please have a look.

Thank you very much.
