Hi Toñi ,
That error comes from the fact that 'java.util.List' doesn't specify
type of its' elements type. As consequence string can't be casted to
generic oclstdlib::T type.
I'd suggest here either change AType.class attribute type to NMTOKEN
with [0..-1] multiplicity or provide black-box Java library to set value
for such attributes.
Regards,
Sergey
