Hello,

I am encountering major issues with Complete OCL, I really do not know what to do. I guess I must be doing something wrong?

I have a fresh installation of Eclipse Modeling 2023-12 (from Oomph) on Java 17, on which I installed OCL 6.19 "All-in-one SDK" from the update site (https://download.eclipse.org/modeling/mdt/ocl/updates/releases/6.19.0). I am on a new empty workspace (no .metadata, no nothing, everything is fresh).

I create a project, I create a .ecore meta-model, so far so good. Then I try to create a Complete OCL document. I get an error dialog about "Cannot modify resource without a transaction". When I close the OCL and I open it again, I get an error view instead of the editor, with the following error and stack trace:
java.lang.IllegalStateException: Cannot modify resource set without a write transaction

Of course, loading an OCL file on an .xmi model created with "Create Dynamic Instance" is out of the question (it crashes the editor with a similar stack trace).

Am I doing something particularly wrong? Is my configuration not good in any way? Is this maybe a bug with Complete OCL? I have ran out of options to be honest...

G. D.

Hm. This is impossible. Eclipse OCL does not use org.eclipse.emf.transaction.

Are you sure that you are not using Papyrus or Sirius?

Please raise a Bugzilla with clear repro instructiions and a copy of Help->About Eclipse->Installation Details->Configuration

Maybe 6.18 might be better.

Yes I am quite sure this is Eclipse Modeling 2023-12...

I submitted a bug report as you suggested (https://bugs.eclipse.org/bugs/show_bug.cgi?id=582958).

I tried installing OCL 6.18 but it seems Eclipse cannot perform the installation because of missing dependencies. For the record:
Cannot complete the install because one or more required items could not be found.
  Software being installed: OCL All-In-One SDK 6.18.0.v20221201-0557 (org.eclipse.ocl.master.feature.group 6.18.0.v20221201-0557)
  Missing requirement: OCL build support for the Xtext Declarative Serializer 1.18.0.v20221201-0557 (org.eclipse.ocl.examples.xtext.build 1.18.0.v20221201-0557) requires 'osgi.bundle; org.eclipse.xtext.generator [2.9.0,3.0.0)' but it could not be found
  Cannot satisfy dependency:
    From: OCL Build Support 6.18.0.v20221201-0557 (org.eclipse.ocl.build.feature.group 6.18.0.v20221201-0557)
    To: org.eclipse.equinox.p2.iu; org.eclipse.ocl.examples.xtext.build [1.18.0.v20221201-0557,1.18.0.v20221201-0557]
  Cannot satisfy dependency:
    From: OCL All-In-One SDK 6.18.0.v20221201-0557 (org.eclipse.ocl.master.feature.group 6.18.0.v20221201-0557)
    To: org.eclipse.equinox.p2.iu; org.eclipse.ocl.build.feature.group [6.18.0.v20221201-0557,6.18.0.v20221201-0557]


I will look into it but this means I may have to use an older version of Eclipse...

Thanks for raising https://bugs.eclipse.org/bugs/show_bug.cgi?id=582958 which it appears you are not getting emails from. Please read my comments / requests there.

(Going back to 6.18 may indeed be difficult since Xtext retracted longstanding functionality in 2023-12. You need the previous Xtext too.)

Fixing this issue joins Bug 582722 as my top priority for 6.20.0RC1 this week. If you can wait, struggling with old versions may be a bit pointless.

A better workaround may be to ensure that you use the Java / Plugin rather than Modeling / Sirius perspective when using an OCL editor.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=582958 fixed for 2024-03RC1.

Problem probably caused by use of OCL->Save Abstract Syntax persisting a *.oclas file that confuses the Modeling Perspective *.aird update.

Workaround of using Java/Plugin perpective should work.

Repair is to manually edit the *.aird to remove *.oclas semanticResources.
