Hello,

is there any way of indicating in HUTN that a reference is empty?

I tried unsuccessfully different options ( null, OclUndefined, none,
nil, etc.) being null the one that provides a non-standard error
message. With null I get the following error (trying to assign the
useCase attribute of a UML Class to null):

org.eclipse.epsilon.hutn.exceptions.HutnTranslationException : Property
'values' not found in object
org.eclipse.epsilon.hutn.model.hutn.impl.NullSlotImpl@1f36902 [line: 0,
col: 0] [feature: useCase] (262:21)

Thanks.
