[news.eclipse.modeling.m2m] EMF M1 model transformation with ATL

["Rainer Bernhard" <rb_account@xxxxxxxx>]

Hello!

as a beginner, I face some trouble with transforming a model (MOF M1),  
which is an instance of my own meta-model (MOF M2).
Enclosed, you  can find the SOURCE MOF M2, SOURCE MOF M1, TARGET MOF M2  
and ATL Model.

Following structure of the SOURCE MOF M2:
- root Element is "Geschaeftsprozess" which has 0.* "GPElement"
- "BetrieblichesObjekt" extends "GPElement"
- "DiskursweltObjekt" extends "BetrieblichesObjekt"

I want to transform all "DiskursweltObjekt" in a "Person" of the TARGET  
MOF M2....(just a sample).
However, the output is just an empty xmi-file (<?xml version="1.0"  
encoding="ISO-8859-1"?><xmi:XMI xmi:version="2.0"  
xmlns:xmi="http://www.omg.org/XMI"/>).

I came up with the following possible sources:
- Addressing "GP!DiskursweltObjekt" is not correct due to the structure of  
the Metamodel (SOURCE MOF M2)
- the SOURCE MOF M1, which was generated from EMF Editor is not correct

Can you help me?

By the way: I tried to start the debug mode. I set some breakpoints (in  
the outline of the atl-file).
however, I didn't succeed to do that. It just "runs through" and generates  
the empty target-file without even switching to the debug-perspective!

Thanks a lot

Rainer
