[EMFTVM] Problem with inout model in ANT lauch file [message #1333836]

Hello,

I have defined an ATL transformation with an inout model. In the Eclipse launch configuration I have defined that the input model is located in a folder, but the update input model is serialized in other folder, this configuration work properly. The problems occours when I try to defined this launch configuration in an ANT Task. I defined the loadMetamodel and loadModel tasks, also I have defined de inoutput property for the emftvm.run task but I don't know where set the output path for the inoutmodel.

<emftvm.run modulepath="platform:/resource/migraria.m2m.strutsConfig_java_MIGRARIAMVCViewAndModel2MIGRARIAMVC_Controller/transformations/" module="strutsCfgJavaMVCViewModel2MVCController">
			<metamodel name="mmMIGRARIAMVC"/>
			
			
			<inoutmodel name="inMIGRARIAMVC" as="IN"/>		
						
			<outputmodel name="trace" as="trace" wspath="migraria.m2m.strutsConfig_java_MIGRARIAMVCViewAndModel2MIGRARIAMVC_Controller/mTarget/trace.xmi"/>
		</emftvm.run>

You can set the output path by defining the "wspath" on the inoutmodel element. Example:

http://git.eclipse.org/c/mmt/org.eclipse.atl.git/tree/plugins/org.eclipse.m2m.atl.emftvm.compiler/compiler-compiler/build.xml?id=2bcbeec856bbd9b2488c17c30ffd34c5449505a0

See line 117.

Hi,

I follow the example, but I have a problem. In the transformation I set references to existing elements in the in/out model before the transformation. If I run the transformation with Eclipse launch the references point to elements of ouput model, but when I use the ANT task the references point to input model. And I'd like that transformation run with ANT task as when I launch with Eclipse.

Best regards

The new Resource URI on the in/out model is set only when executing the emftvm.run task. You must save any models referring to the in/out model AFTER running the emftvm.run task.

Hello,

I save the models using the emftvm.saveModel task. The problem is that some of the references creates in the transformation between existing elements in the in/out model an the new elements in the in/out model are serialized as references to the elements in the model file use as input instead of set reference to the copy of elements in the new output model.

Victor, can you show me your build.xml? I can better understand what you mean
that way.

I attach the build.xm and this is the model transformation head

module strutsCfgJavaMVCViewModel2MVCController;
create OUT: mmMIGRARIAMVC refining IN: mmMIGRARIAMVC, inJava: mmJava, inStrutsConfig: mmStrutsConfig, inModelTrace : mmTrace;

This is an excerpt of the output model generated when I run the transformation using Eclipse launch:

      <operations xsi:type="Controller:DataOperationCall" name="confDAO.get" dataOperation="//@model/@objects.1/@operations.3">
        <params xsi:type="Controller:DataOperationCallParameter" name="confId" instance="//@controller/@controlFlows.0/@instances.1" parameter="//@model/@objects.1/@operations.3/@parameters.0"[/color]/>
        <return name="DeclarationFragment conf" return="//@model/@objects.1/@operations.3/@return" instance="//@controller/@controlFlows.0/@instances.2"/>
      </operations>

And this is the excerpt of the model generated running the transformation with ANT task

      <operations xsi:type="Controller:DataOperationCall" name="confDAO.get">
        <params xsi:type="Controller:DataOperationCallParameter" name="confId" instance="//@controller/@controlFlows.0/@instances.1">
          <parameter xsi:type="Model:DataOperationParameter" href="../mSource/migraria_view_and_model.xmi#//@model/@objects.1/@operations.3/@parameters.0"/>
        </params>
        <return name="DeclarationFragment conf" instance="//@controller/@controlFlows.0/@instances.2">
          <return xsi:type="Model:DataOperationReturn" href="../mSource/migraria_view_and_model.xmi#//@model/@objects.1/@operations.3/@return"/>
        </return>
        <dataOperation href="../mSource/migraria_view_and_model.xmi#//@model/@objects.1/@operations.3"/>
      </operations>

The differences are in the attributes dataOperation of element operation, parameter of element param and return of element return.

Sorry for the delay: I cannot see any mistake in your build.xml file, so I will have to do some additional testing.

I cannot reproduce you problem with a simple test project (see attached "AntTest".zip" project). Can you zip up a full project that allows me to reproduce your problem?

Hello

I attach a project where I try to reproduce the error simplifying the transformation rules and metamodels. In the process I found another error that didn't allow me to reproduce the same error that I get in my original project, but I think it is related to the original error. The problem that I found is when I load a model and the trace model of transformation that generated it. If I query the elements in eclipse launch the model elements and the target elements in trace model there are the same instances. But when I try running the ANT task the instances are different from the input model and the trace source elements.

Best regards,
Víctor.

...ok, that took a few months Shocked

Short story:

Turns out you should not set the wspath of your inout model within the emftvm.run task, but only in the emftvm.save task.

Long story:

EMF lazily resolves ERereferences to other models (eProxies). See org.eclipse.m2m.atl.emftvm.trace.impl.TraceElementImpl.getObject(). The proxy EObject for:

traceLink.targetElements.first().object

is only resolved when EMFTVM reads it, at which point the URI of the "person.xmi" model has already changed to "person_ANTLaunch.xmi" (this is done before the transformation starts). As a result, your "person.xmi" model is loaded again, and you've two instances of the model in memory.

I've attached the fixed build.xml script.
