Hello,
I added a variable named "objectlist" to the OCL Environment, which is
an EcoreEnvironment, of type EEList.
When I try to evaluate for example the expression "objectlist.at(1)" a
NullpointerException is thrown
(caused by line 225:
result =containerClass.getMethod(operName,javaParms);
in EcoreEvaluationEnvironment).
So am I doing something wrong or is EEList not supported?
Best regards,
Lilija

Hey,
I fixed the problem by setting the type of the variable to the OCLType:
var.setType(ocl.getEnvironment().getUMLReflection().asOCLType(EcorePackage.Literals.EE_LIST));
regards
Lilija
