[mdr-users] CompositionViolationException with Association

Hello,

perhaps someone could help me with my problem. I'm trying to develop a tool
which creates a JMI model from a XMI file generated by Together. For this I
use some AndroMDA classes for reading the model.

The problem is that everything works fine when I draw an UML model
without any association. If I do so I get a CompositionViolationException.
I
thought the problem occured because of Together but I get the same
Exception when I create a model with MagicDraw. I'm a newbie to UML 2.0,
XMI and MDR.

I send you the generated XMI file of the model. There are only 2 classes
(Class1 & Class2) with an association between them called
'{Class1-Class2}'. The XMIReader and the MDRepositoryFacade I use are the
same that are used in AndroMDA. The metamodel is
'M2_DiagramInterchangeModel.xml'. I debugged the whole program and walked
step by step through the XMI. The problem occures in the end of the
<UML:AssociationEnd> tag at line 62 in the xml file. The
reader uses org.netbeans.lib.jmi.xmi.XMIElement which has the method
'endElement' which tries to create an RefObj (createInstance()). There you
have a list of attributes and references. With the attributes everything
works fine. When the XMIElement checks the references it tries to make a
ReferenceHandler and sets the reference
(XMIElement.ReferenceHandler.setReference()). There it tries to make 2
RefObjects and link them via RefAssociation.refAddLink(). However I
don't have the source of AOwnerFeature$Impl and cannot see where exactly
the
Exception is thrown.

Another thing confusing me is the 'export' function in together. I choose
there the XMI 1.2 and UML 1.4 (OMG) versions. But in the XML file stands:
'<XMI xmi.version = '1.2' xmlns:UML = '//org.omg/UML/1.3'>' in line 2.

In line 12 you find:
'<XMI.metamodel xmi.name = 'UML' xmi.version = '1.4'/>'

Am I using UML 1.4 now?

I hope this mail is not to detailed and comprehensible. So I'm working on
the problem since several days and would be very glad about any answer.

Thanks in advance!
