I am trying to create an OCL expression where the value can be anything
(i.e. an EObject, a primitive, an enumeration).
I get a Sematic exception (ERROR in (variableExpCS): (Unrecognized
variable: (ACTIVE))
when executing the following:
ExpressionsUtil.createQuery(environment, "ProductStatus.ACTIVE", true)
ProductStatus in an Enumeration where ACTIVE is one possible value.
Assuming that this API is the right API, Do I need to prepare the
"environment" to let it know about the enumerations?

Hi, Kagan,
No, you just need to use the OCL syntax for qualified names, which uses the
UML-style '::' separator instead of the Java-style '.':
ExpressionsUtil.createQuery(environment, "ProductStatus::ACTIVE", true);
OCL thought you were trying to access a static property named "ACTIVE" of
the ProductStatus classifier. :-)
Cheers,
Christian
