[news.eclipse.modeling.m2m] Re: [QVTO] Help with syntax for assigning va

[Sergey Boyko <sboyko@xxxxxxxxxxx>]

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
