Hi, i'm trying to access the value of an external reference using the
reflective operation refGetValue. My input element is "s" and i'm
iterating over it's structural features. The feature "f" of the element
"s" is an external reference.
s.refGetValue(f.name)
I don't have problems with local references, but I receive the
following exception when I try to access the external one.
