Hello,

I am trying to do a simple transformation in Medini QVT.
I defined two metamodels in ecore format one as TreeMM and the other is NodeMM(respectively for source and target metamodels)

TreeMM: just have one attribute as name+ two Ereferance as parent and child
NodeMM:have one attribute as name + one class of edges +one class of root
in edge class we have source and target az Ereference which have type NodeMM
in root class we have two reference as edges and nodes.

in the next step I created instance of ecore from TreeMM.ecore and called it Tree.XMI

I wrote the transformation in .qvt format as follow:

transformation tree2graph(tree:TreeMM, node:NodeMM) {

-- map each package to a schema
top relation TreeToNode {

tn : String;

checkonly domain tree t : TreeMM::TMM1 {
name = tn
};

enforce domain node n : NodeMM::NMM2 {
name = tn
};

}

no I am trying to execute this transformation

I open new configuration
my first qustion is what should I put in traces directory, is it going to create automatically?is it enough i just give the transformation folder path.

I gave the transformation path and then i run it
I have this error:
Exception accured in transformation
reason:
Error:241:1 syntax error
Error: 1 couldnt repair and continue parse

when I push details:
java.lang.NullpointerException

Trac detected an internal error

I don't know what "Trac detected an internal error" means. Sounds more
like a "Trac" problem than one with this forum. Note the activity in
this forum over the last week would seem to indicate that it's working.
