OCL invariants in ecore file doesn't work reliable [message #1187823] Fri, 15 November 2013 09:50 Go to next message

Hi all,

I have a problem with the OCLinEcore editor and I already wrote a bug report to Eclipse, but didn't receive any answer. Could anybody help me? It's a really strange thing: I write some OCL invariants with the OCLinEcore editor in my meta model file, then I save and close it. When I reopen the file in OCLinEcore, the invariants are crashed (see bug report: https://bugs.eclipse.org/bugs/show_bug.cgi?id=416641). Do you see an error in my code or is this an error of Eclipse?

Thanks in advance,
Yannic

Hi

Unfortunately you raised Bug 416641 against the MDT/MST project rather
than the OCL project. The MST project is almost dead so nobody saw your
report. I've transferred the bug to MDT/OCL.

What you are doing looks perfectly reasonable so I've added a comment to
the bug requesting your full repro.

Up until Kepler, saving an OCLinEcore file as *.ecore when it contains
errors would lead to losses. The lossy save should be inhibited in Kepler.

[As a general guide, don't wait two months before inquiring further, two
working days is a reasonable delay if it's urgent for you.]

Regards

Ed Willink

Thanks for your hints! So you would say that it should work with Kepler? Because I use at the moment Juno and I tried now to import my projects in a Kepler instance and there I didn't get the described error... Unfortunately I can't use Kepler for my whole work because some required modelling plug-ins are not compatible with Kepler at the moment. Is there any chance to get a bug fix for Juno?

Hi

I'm afraid there is very little chance of a Juno fix; I'm working
towards Luna.

However the Kepler code should be installable on Luna provided you are
prepared to take a Kepler Xtext too.
