Hello Willian,
I want to do the second option, that it is:
helper context <some metaclass> def: getSomeEnumeration() :
UML!Enumeration = <helper code>;
But my doubt is : how I create and return a enumeration.
Example:
I have a enumeration that its name is MCD_MetaModel!TipoCardinalidad and
it has the following values: #Cero_a_uno, #Cero_a_muchos, #Uno and
#Uno_a_muchos.
I want to create a enumeration of this type that its value will be #Uno.
How do I do this helper?
helper def :getCardinality (cardinality: Logical!CardinaltyType) :
MCD_MetaModel!TipoCardinalidad = ?¿?¿?¿?¿?
The parte has ?¿?¿? I don't to do.
Thank you.

Hello Wllians,
I have de following helpers:
helper def :getCardinality (cardinality: Logical!CardinaltyType) :
MCD_MetaModel!TipoCardinalidad =
if (cardinality=#ZERO_TO_MANY) then
#cero_a_muchos
else
#cero_a_uno
endif;
When I execute the helper, this produces next exception, do you know which
is my problem:
