[OCLinEcore] definition of operation works in OCL console, but not in other modules like Acceleo [message #559009]

Hello,

I have created an operation at a Class like:

class Namespace {
   attribute prefix : String;
   attribute fully : String;
   
   operation asString() : String {
        body: prefix.concat(':').concat(fully);
    }
}

This method works only in the OCL console. But not in other systems that use the same EMF model. How can this be? Do I have to generate the code in another way to make these operations work?

Best regards,
Simon

Hi Simon

The support for OCL delegates was introduced at Helios M6 and should
work provided appropriate registrations are in place which should happen
automatically.

However there a variety of ways of using EMF that not all modeling
projects support consistently.

Please make clear exactly how you were using your model and exactly how
you were invoking some other system, so that we can pinpoint the
troublesome combination.

Regards

Ed Willink

Thanks for the information. It directed me to the delegation registration code you provided earlier and is stated also here: http://wiki.eclipse.org/MDT/OCLinEcore#Standalone

I just had to add the code before the transformation/loading of the EMF resource. Then, everything worked smoothly.
