Hello, I trying to regenerate the Activity Diagram in MDT Papyrus and I think I may have I have seen the same problem when using GMF Tooling 2.4. It's due to an error in QVTO. This error was corrected with the version 3.1.0. The problem is that GMF Tooling dependencies used QVTO [2.0.0,3.0.0). The solution is then to use a custom GMF Tooling feature. I will put it in attachment and you can try it if you want. But there still a lot of problem still after. After some searching some times I found this bug and I think it might be related. See https://bugs.eclipse.org/bugs/show_bug.cgi?format=multiple&id=346952. Hoping it will help you. Here you can find the custom GMF Tooling: http://dl.dropbox.com/u/1059994/GMFToolingFeature.zip Here you can find the 3.1.0 QVTO version: http://dl.dropbox.com/u/1059994/m2m-qvtoml-Update-3.1.0RC1.zip Can you please tell us where you got your version of GMF-Tooling 2.4? Maybe it was not up-to-date... Also can you please describe us the steps to reproduce the issue? Is this simply about checkout a gmfgen and running the generation? We could probably incorporate your model to GMF Tooling test suite... Hi, First thanks you for answering so quickly. I have taken the GMF Tooling from: GMP - http://download.eclipse.org/modeling/gmp/updates/milestones/site.xml with this version I got the NPE describe by Patrick Tessier. So I have look for an upgrade of QVTO. And I have found the 3.1.0 version that should correct the bug. But with the GMF Tooling version I have got from the update site I didn't succeed in using QVTO 3.1. So I have downloaded sources from the CVS and on this version the depencies were correct. So I have exported the feature and install it. Ok, I got it. You seem to clearly understand the issue. Can you provide a patch that you used to fix the issue? If it looks good, I'll commit it, run the test, and it will be part of the 2.4 release. If you can't, we'll do the necessary for getting this fixed for the release, but it won't be immediate. Nothing has to be corrected because on the CVS version the dependencies are correct but the no existing build with this correction. So I simply build the GMF Tooling feature and use it with QVTO 3.1. However the real problem is that with GMF 2.4 I got this error: Description Resource Path Location Type IllegalValueException: Value 'org.eclipse.emf.ecore.impl.DynamicEObjectImpl@107c32f (eClass: org.eclipse.emf.ecore.impl.EClassImpl@6be589 (name: GenChildSideAffixedNode) (instanceClassName: null) (abstract: false, interface: false))' is not legal.

I do not get this error when I try to generate with GMF Tooling 2.3.0 version.

Arthur, could you please point me to the input resources to reproduce this issue? Assuming it may be a common problem with side-affixed nodes, I've tried that with minimal diagram with pin-like structurtes but it works fine for me, so it may be related to the specifics of your diagram. Thanks for your help but after updating all needed features the bug has diseapered. If I find it again I will go back to you. Thanks a lot. Arthur Closing as fixed. version -> 2.4 Rollback, Set target to 2.4 instead of accidenatlly set Version |
