Dear all,
I'm trying to create a profile in Papyrus and I would like to add
several constraints, i.e., limiting the range in an integer value.
To do so I need to get access to the value of the properties of my profiles.
If I write in the OCL Interactive view in the console it works:
self.getValue(getAppliedStereotype('Profile::Requirement'), 'id') = 4
Nevertheless, if I create an class and then I apply the stereotype and I
right-click to show the context menu and I click in Validation->Validate
Model I get the following error:
Description Resource Path Location Type
An exception occurred while delegating evaluation of the 'Constraint1'
invariant on 'Requirement -> <<Requirement>> <Class> Class1':
org.eclipse.ocl.common.internal.delegate.OCLDelegateException: Errors in
'self.getValue(getAppliedStereotype('Profile::Requirement'), 'id') = 4
'
1: Unresolved Operation
'Profile::Requirement::getValue(getAppliedStereotype('Profile::Requirement'),
'id')' model2.uml /PruebasOCL_Luna Unknown EMF Problem
Could please someone help me to find a workaround?
Kind regards,
Víctor

Hi
Support for OCL has been steadily improving (and it's not perfect in
Luna M6).
What version are you using?
You should not need to use the Java API. Rather
self.extension_Requirement.id = 4
will avoid loss of types.

Dear Ed,
First, thanks for your quick answer.
I'm using Eclipe Luna M6 and Papyrus 1.0.0v201403121345. Is there a
better combination of tools for OCL support? Should I install something
else?
Writing "self.extension_Requirement.id = 4" doesn't work in the Xtext
OCL console. Moreover, it isn't recognized properly in the editor of the
constraint, extension_Requirement doesn't show in the autocomplete feature.
I have attached a tiny project with a single stereotype and a single
class where this issue appears, in case it helps.
Regards,
Víctor

Hi
This looks rather related to
https://bugs.eclipse.org/bugs/show_bug.cgi?id=431638 where I've
discovered that the UML support is getting very confused as to whether
it is working in the OMG-UML/Eclipse-UML namespace. The console support
seems to have a further confusion by converting to the Pivot model
prematurely.
I hope to have this fixed soon.
Regards
Ed Willink
