[ATL] Programmaticcaly launch, inter-model reference null, proxy problem ? [message #644003] Thu, 09 December 2010 01:41

I'm a PhD student from France and i'm currently working with ATL. I have developed several ATL transformation modules, and everyones work with the ATL Launch Run Configuration.

Now, i'm trying to automate the several transformations using the programmatically launch. First, i use the generated java classes from the ATL plug-in wizard.

Everything work if i have as input a model without reference to another model. In the case of the inter-model references i have the following exception:

org.eclipse.m2m.atl.engine.emfvm.VMException: Unable to access ownedFeature on OclUndefined
at getListPortsString#11(MBTStep3POHIActivity.atl[333:4-333:29] )
local variables: self=Model!Pinger, thClass=<unknown>!<unnamed>
at __matchGenerateActivityPackage#58(MBTStep3POHIActivity.atl[1 464:40-1464:66])
local variables: self=MBTStep3POHIActivity : ASMModule, thSub=Model!Pinger, thClass=<unknown>!<unnamed>, procCont=Model!Node_A, pckName='PolyORB_HI_Generated_Node_A_Pinger'
at __matcher__#1(MBTStep3POHIActivity.atl)
local variables: self=MBTStep3POHIActivity : ASMModule
at main#34(MBTStep3POHIActivity.atl)
local variables: self=MBTStep3POHIActivity : ASMModule

As we can see, the thClass object is null. It should be an object retrieved with EMF reference. I think it may be a proxy problem to resolve EMF reference.

Here the code to launch the transformation:
MBTStep3POHIActivity runner = new MBTStep3POHIActivity();

IResource aaxlFile = OsateResourceManager.convertToIResource(declarativeObject.eR esource());

IPath path = aaxlFile.getFullPath();


IPath output_path = path;

The value of the path is:
current FULLPATH: /Osate2Test/aaxl/packages/ping.aaxl2

And the EMF reference of the object thClass in the input model is:
<threadClassifier xsi:type="aadl2:ThreadImplementation" href="software.aaxl2#_LzNeggMfEeC0Q_gQsxRmow"/>

I think the file "software.aaxl2" is not found.

Do you have any idea ?
