Hello,

I want to use refining mode in ATL. I have the same metamodel in input and output.

I have a object Activity which has relation (Transition) with an other Activity.
Transition 1 ----> Activity A ----> Transition 2

I want to split the activity A into 2 Actiivty (A and B) and create a new transition between A and B :
Transition 1 ----> Activity A ----> Transition 3 ---> Activity B ----> Transition

My code is like this :
Rule Split {
from
s : Xpdl!Activity (....... test.....)
to
t : Xpdl!Activity (
transitionsFrom <- t2
),
t1 : Xpdl!Activity (
transitionsFrom <- s.transitionsFrom,
transitionsTo <- t2
),
t2 : Xpdl!Transition ()
}

When I execute this transformation i have this error :
org.eclipse.m2m.atl.engine.emfvm.VMException: Cannot create XPDL!Transition

Can somebody help me please ?
