OclType and oclAsType issues [message #665974]

Hi,

I am trying to do the following:

myClass := myMetaModel.rootObjects()[EClass]->asSequence()->first();

someObj.oclAsType(myClass);

The type checker rejects the second statement. The signature of oclAsType suggests that it requires an OclType. Isn't that removed from the new OCL spec? What am I supposed to cast myClass to, to make the typechecker happy?

thanks

Hi Al

oclAsType, as typically implemented, requires a type literal, e.g. MyClass.

oclAsType, as specified, is unimplementable; type expressions are not
adequately defined.
