Hi,
i get strange problem with the ocl parser.
I want to parse a query which uses the method getAppliedStereotypes in it. When i parse it with the OCL class i get the following error:
org.eclipse.ocl.SemanticException: Cannot find operation (getAppliedStereotype(String)) for the type ...
The context for this query is a Class so it should have this function.
The other strange thing is, if the query is executed in the interactive ocl console it works fine.
Does anybody know this error and why it raises?
Regards,
Andreas

Hi,
thank you for your fast respond. I added a zipped eclipse project which demonstrating the error.
It contains an uml model with MARTE and SysML stereotypes in it, a model loader class, a ocl parser class and a test class.
Running the test class the uml model will be loaded and the constraint in the uml model will be parsed.
Thank you for your support.
Regards,
Andreas

Hi,
I happened to stumble over the exact same problem just now. The issue is the
UML metamodel used by the UML OCL engine, which is loaded from
UMLResource.UML_METAMODEL_URI (pathmap://UML_METAMODELS/UML.metamodel.uml) [1].
Since UML2 4.0.0, this model no longer seems to contain the non-normative
operations like getAppliedStereotypes, hasKeyword, etc.
I was only able to find these in
platform:/plugin/org.eclipse.uml2.uml/model/UML.uml
So my questions would be:
1) Which of these models should be used by the OCL UML plugin or other
consumers of the UML metamodel?
2) If the one currently used (i.e. without those operations) is the right
one, how else can these features be accessed in OCL?
[3) What's the rationale behind removing those operations in the first place?]
Best regards,
Carsten
