Hello,
I'm trying to link with GMF two attributes defined as:
<xsd:attribute name="pipe" type="xsd:ID" use="required"/>
..
..
<xsd:attribute name="pipe" type="xsd:IDREF" use="required"/>
I modeled the attributes with EMF using the annotation datatype ID and
IDREF, and I used a link map with only the target property set to
pipe:ID. As result I got:
!ENTRY org.eclipse.gmf.validate 4 300 2008-06-06 08:30:12.348
!MESSAGE Validation failed unexpectedly for 'Type Model Facet'. See log
for details.
!STACK 0
java.lang.NullPointerException

What is wrong in this approach?
Thank you for the answer,
