Hi,
I converted from ATL 1 to ATL 2.0.0rc2, but I get a NullPointerException
when calling it from Java:
java.lang.NullPointerException
at
org.eclipse.m2m.atl.engine.AtlEMFModelHandler.saveModel(AtlE MFModelHandler.java:144)
at
org.eclipse.m2m.atl.engine.AtlEMFModelHandler.saveModel(AtlE MFModelHandler.java:65)
at meta.presentation.MetaEditor.doATLTransformation(MetaEditor. java:381)
MetaEditor.java:381 :
this.amh.saveModel(this.models.get("OUT"), outModel);
using:
AtlModelHandler amh
ByteArrayOutputStream outModel
this.models.get("OUT") retrieves ASMEMFModel OUT from a HashMap. It is
created as:
ASMEMFModel outputModel;
outputModel = ASMEMFModel.newASMEMFModel("OUT", "OUT",
this.metaModel, this.ml);
outputModel.setCheckSameModel(false);
using:
ASMEMFModel metaModel;
protected EMFModelLoader ml;
Changing the second "OUT" string to "" or null doesn't help.
Any ideas?
Thanks,
Rene
