Hi.

I have an Stereotype with a property. The property's type is an
Enumeration.
The problem is: even if I set the multiplicity to [0..1], my property does
not allow a null value.
Worse, it assumes the first enumeration literal as the default value.
Looking in the profile generated definition I found that it picks the
first value as the default.

I don't think this is the expected behaviour for UML...
my reasoning is...if I set [0..*] it will generate an infinite list of
default values ? of course not...

Do I have to create an specific literal named NULL ?

Thanks
