Hi,

when trying to use the OCL to create an Audit Rule e.g. 'name.size()>0'
for one of my domain elements I receive a message in my generated RCP
Editor after invoking 'validate' on the diagram via the Menubar:

- The constraint "xxx" is disabled. It will not be evaluated.
- and in the preferences for "Model Validation - Constraints" I am now
able to see that the constraint has been disabled: "This constraint is
disabled because of a run-time error and cannot be selected."

The same behavior I get when adding the example Audit Rule to the mindmap
example.

Any ideas? Thanks for your help.

With best regards
Markus

Hi, Markus,

This is what the EMF Validation Framework does when constraints throw
RuntimeExceptions during validation; they are basically booted from the
system for the remainder of the session.

The workspace log file should have a stack trace of the exception that
occurred; it will provide a clue to what the root cause is.

HTH,

Christian

Thanks a lot... :)

Two other plug-ins have been missing in my launch configuration and
although using the 'add required plug-ins' button these plug-ins have not
been added to my configuration (include optional plug-ins was activated;
Eclipse 3.4M6):

- org.eclipse.emf.ocl
- org.eclipse.emf.validation.ocl

Now everything works fine (after adding them manually) but I'm a little
bit surprised that they have not been added automatically to my
configuration (there have also been no errors when validating the plug-in
dependencies).

With best regards
Markus

Hi, Markus,

Yes, the trick here is that there is no plug-in actually dependent on
the org.eclipse.emf.validation.ocl. It is a leaf plug-in that plugs
in animplementation of the "OCL" constraint language.

Although no other plug-in in the EMF Validation Framework SDK depends
on it, probably GMF should because it requires it for OCL-based
validation.Perhaps GMF is missing a Require-Bundle dependency?

Cheers,

Christian
