Parsing error in a UML::Constraint [message #1720195]

I created a sample model in Papyrus with single constraint following the instructions given by the OCL documentation for defining a Class invariant. I get a the following parsing error on the constraint:

Failed to load 'platform:/resource/Test/Sample.uml.oclas

What do I need to do to have this file generated?

Hi

Without a repro, you are unlikely to get a solution.

*.oclas is the, normally only internal, name of a model normalized to
the OCL Pivot Abstract Syntax. *.oclas is normally registered so that
any access strips the extension, tries again to load the unnormalized
file, then normalizes it. (*.oclas is the prototype for the long overdue
ability to have a defined OCL XMI.)

Possibly you have fallen foul of

https://bugs.eclipse.org/bugs/show_bug.cgi?id=485668

although your error message bears little resemblance to

https://bugs.eclipse.org/bugs/show_bug.cgi?id=483181

The above bug is fixed in the latest OCL builds towards Mars.2 and Neon.

Ed,

Thanks for your reply. I apologize for taking so long to react, I was stuck on another topic.

I updated my OCL version with the one you provide (for Mars) but the error is still there.

I provide the model this time.

Thanks,

Hi

Sorry, I am unable to load your model. It uses SysML 1.4 facilities that
are not part of the Papyrus 1.2.0M4 distribution and not in the Papyrus
Additional Compoents.

Once I upgraded this model to the SysML 1.4 profile in my installation (ie. after the migrate profile functionality from Papyrus pops in), your constraint parses fine. Which version of papyrus/sysml1.4 are you running?

Hi Klaas,

Interesting...

Here is the info I can get from the SysML1.4 plugin:
Papyrus Sysml 1.4 Feature (Incubation) 0.7.0.201511250947 org.eclipse.papyrus.sysml14.feature.feature.group Eclipse Modeling Project

Thanks,

I modified the sample in order to remove the SysML profile and then the problem vanished...
If I reapply the SysML 1.4 profile the problem reappears but it is not with the case with the profile corresponding to SysML 1.1.

So it appears that there is an incompatibility between the version of the SysML 1.4 profile plugin I use and the current version of OCL.

Klaas, I'm interested to know which version of this plugin you use.

Thanks,

Hi,

AFAIK if you're using SysML 1.4, bleeding edge is the most stable (generally Smile
