juno upgrade - uml2.types [message #1000280]

I have a dsl backed-up by an UML model that was working just fine for Indigo but when upgrading to Juno I can't just get it to work anymore.

The issue seems to be due to the change from UML 2.2.0 to 4.0.0 and now when I refresh the genmodel it shows me the 'Types' package that wasn't there before... if I try to reference it the mwe workflow stops with this transformation diagnostic error:
The existing attribute 'reference' has an incompatible type 'null'. The expected type is 'EString' [java.lang.String]. (ErrorCode: CannotCreateTypeInSealedMetamodel)

The primitive types in the generated ecore model were changed from EString to String, I added the uml2 import in xtext file but doesn't change anything (import "http://www.eclipse.org/uml2/4.0.0/Types" as types)... is there something that need to be added to the mwe workflow? I only have one registerGeneratedEPackage there that point to the generated model code from the source UML.

Sorry for the basic question, I don't seems to be able to find a way through... any hints?

Thanks,
Marian

just tried to remove the reference and generated the model for Types as well, not the workflow happily runs but this doesn't look like a real solution does it? Sad

Hi

The additional support for UML 2.4.1's separate Types package caused a
few hiccoughs (https://bugs.eclipse.org/bugs/show_bug.cgi?id=382637).
Make sure you use SR1.

I think the above should fix your problem. If you're unlucky you might
get hit by https://bugs.eclipse.org/bugs/show_bug.cgi?id=389542 which
requires a more recent maintenance build or SR2 (coming shortly).

Regards

Ed Willink

Did you do what was suggested in the comments section of

first sorry for being so stupid no to turn on email notifications on the post Sad

Ed, I'm using Juno 4.2.1 Build id: M20120914-1800 and I do see the option to 'reference' the Types package which is what I do.

The data type reference in ecore is like this: eType="ecore:EDataType http://www.eclipse.org/uml2/4.0.0/Types#//Boolean"

Christian, not sure if I need to register all ecore files and genmodels as I'm not directly using a UML file but the Ecore/EPackage generated out of it... however I did tried to register the uml2.types first like this:

uriMap = {
  from = "platform:/plugin/org.eclipse.uml2.types/model/Types.genmodel"
  to = "platform:/resource/org.eclipse.uml2.types/model/Types.genmodel"
}

uriMap = {
  from = "platform:/plugin/org.eclipse.uml2.types/model/Types.ecore"
  to = "platform:/resource/org.eclipse.uml2.types/model/Types.ecore"
}

registerGeneratedEPackage = "org.eclipse.uml2.types.TypesPackage"

registerGenModelFile = "platform:/resource/org.eclipse.uml2.types/model/Types.genmodel"

registerEcoreFile = "platform:/resource/org.eclipse.uml2.types/model/Types.ecore"

but then I get a PackageNotFoundException: Package with uri 'http://www.eclipse.org/uml2/2.2.0/GenModel' not found. (platform:/resource/org.eclipse.uml2.types/model/Types.genmodel, 7, 78)

I then tried to register everything as on your blog article, same error only now from platform:/resource/org.eclipse.uml2.uml/model/UML.genmodel.

In xtext file I can import "http://www.eclipse.org/uml2/4.0.0/UML" and "http://www.eclipse.org/uml2/4.0.0/Types"... but "http://www.eclipse.org/uml2/2.2.0/GenModel" is proposed as well, maybe there is something else that I need to register, or the plugin dependencies needs something to be added?

This was working just fine before, all I had to do was to register the generated EPackage... also tried to register the ecore file and the genmodel of my own model but didn't changed a thing Sad

Thanks,
Marian

oh, checking the list of required plug-ins saw org.eclipse.uml2.codegen.ecore was missing... added that and now the error is gone when running the workflow, and it does seems to work.

thanks all for helping me out, did I said xtext rules? Smile

started to look at xbase but it's not very clear to me how this can be used on a Java alike language but not really Java... is it easy to override the operators, primitive data types or to map those somehow to the Java equivalent? (guess this deserves a post on it's own but first I have to check the docs a bit)
