Hi,

in our tool - the MDPE Workbench - we invoke ATL programmatically. So far, we used ATL 3.0.0 and all our transformations worked very well. Recently, we updated the ATL version to ATL 3.0.1 and there is a very strange problem for which we have no ideas how we can solve it.

The transformation takes a so called TIPM model, a Trace model and another annotation (PAM) model as input and generates a new TIPM with additonal annotation information from the PAM model. As mentioned above in ATL 3.0.0 the transformation works fine. If we use ATL 3.0.1, data from PAM is available in the TIPM, but not contained in the model (see the snipped of TIPM).

...
 </org.modelplex.tipm:TIPM>
  <org.modelplex.tipm:OpenWorkload description="WorkloadName">
    <occurence xsi:type="org.modelplex.tipm:ValueTable">
      <tableEntries endTime="303" value="2.0"/>
    </occurence>
  </org.modelplex.tipm:OpenWorkload>
  <org.modelplex.tipm:ValueTable>
    <tableEntries endTime="305" value="20.0"/>
  </org.modelplex.tipm:ValueTable>
...
</xmi:XMI>


The transformation is launched programmatically by the workbench. All required metamodels and models are loaded and access to model elements in the PAM model is possible. The latter, I tested with a helper in the ATL script. This helper is a String and print the value of the name attribute of the first PAM!Workload element to the console by using debug() in ATL.
However, if I execute the transformation manually via a launch configuration, the transformation produces the correct result (the same as in ATL 3.0.0). In both cases, we use the regular ATL VM.

Do you have any ideas what the problem is? Please, let me know if you need addtional information. I have no idea what kind of information is useful for this problem.

Best regards,
Sebastian

What do you exactly mean by "not contained in the model " ?

Maybe it's a problem of model inter-references.

Try :

options.put("allowInterModelReferences", "false");

Both programmatically and using launch configurations ?

Did you try using the latest 3.0.2 build ?

All what you could provide is useful : ATL project, metamodels,
programmatic launch snippet or entire code...
This kind of bug may be quite hard to reproduce, so feel free to submit
materials - attached to your answer - if you are allowed to, regarding
to your confidentiality policy. Otherwise, try to make a simple project
reproducing the bug.

Thanks in advance,

William

Hi,

I tried out the option 'allowInterModelReferences' as well as the ATL 3.0.2 RC1, however with the same result.

In the following, I provide some details how the transformation is executed from our tooling.

In order to invoke the ATL transformaiton programatically we use an additional model, where references to required models and metamodels are stored. We use the following code to prepare the ATL Launcher:

	loadMetamodels(atlTransformationChain);

	for (ATLTransformation atlTransformation : atlTransformationChain
			.getAtlTransformations()) {
		...
		ILauncher launcher = CoreService
				.getLauncher("Regular VM (with debugger)");
		Map<String, Object> initOptions = new HashMap<String, Object>();
		initOptions.put("allowInterModelReferences", "false");
		launcher.initialize(initOptions);
		
		...
		outputModels.addAll(loadModels(launcher, atlTransformation));

		launch(launcher, atlTransformation, outputModels, monitor);
		...
	}


The following loadModels method ( invoked from the method above) is responsible to add source and target models to the launcher.

private List<ATLModel> loadModels(ILauncher launcher,
			ATLTransformation atlTransformation) throws CoreException,
			ATLCoreException {
		...
		Map<String, Object> modelOptions = new HashMap<String, Object>();
		for (ATLModel model : sourceModels) {
			final String modelName = model.getName();
			modelOptions.put(MODEL_NAME, modelName);
			modelOptions.put(PATH, model.getUri());
			modelOptions.put(NEW_MODEL, Boolean.FALSE.toString());
			IModel iModel = defaultModelfactory.newModel(referenceModels.get(model
					.getConformsTo().getName()), modelOptions);
			models.put(modelName, iModel);
			injectors.get(model.getConformsTo().getName()).inject(
				models.get(modelName), convertURI(model));
			launcher.addInModel(models.get(modelName), modelName, model.getConformsTo()
				.getName());
		}
		//similar code for returnModels

		return retModelList;


The following method launch invokes the ATL VM:

private void launch(ILauncher launcher, ATLTransformation atlTransformation,
			List<ATLModel> outputModels, IProgressMonitor monitor)
			throws MDPEException {
		Map<String, Object> options = new HashMap<String, Object>();
		options.put("isRefiningTraceMode", new Boolean(atlTransformation
				.isIsRefinement()).toString());
		options.put("launcherName", "Regular VM (with debugger)");
		options.put("disassemblyMode", "false");
		options.put("continueAfterError", "false");
		options.put("disableAttributeHelperCache", "true");
		options.put("printExecutionTime", "false");
		options.put("OPTION_DERIVED", "true");
		options.put("modelHandlers", modelHandlers);
		options.put("step", "false");
		options.put("profile", "false");


		try {
			launcher.launch("run", monitor, options, new URL(atlTransformation
					.getUri()).openStream());

			// extract all output models
			for (ATLModel model : outputModels) {
				extractors.get(model.getConformsTo().getName()).extract(
						models.get(model.getName()), convertURI(model));
			}
		}...
	}

Hello again,

I tried to set breakpoints in the launch method of class RegularVMLauncher:

- The first breakpoint has been added to the first line: IDebugTarget mTarget = null;
- The second one: if (launchParam != null)

Then I observed resources in the ResourceSet of the EMFModelLoader class at each breakpoint. The ResourceSet is referenced in the models attribute of RegularVM launcher.

At breakpoint 1 (before transformation execution with ATL 3.0.1 / 3.0.2RC), the ResourceSet contains:

[org.eclipse.emf.ecore.xmi.impl.XMIResourceImpl@117bc60 uri='file:/C:\Users\Sebastian\Desktop\WinesellerAnnotaions\Core.mdpe', 
...XMIResourceImpl@1505ddb uri='file:/C:\Users\Sebastian\Desktop\WinesellerAnnotaions\Parameter.mdpe',

...ToolResource@161b165 uri='file:/E:/01Test/ToolIntegration/runtime/Configuration/.metadata/.plugins/org.modelplex.mdpe.workbench.core/Dev2TIPM.trace']


At breakpoint 2 (after transformation execution with ATL 3.0.1 / 3.0.2RC), the ResourceSet contains:

...XMIResourceImpl@117bc60 uri='file:/C:\Users\Sebastian\Desktop\WinesellerAnnotaions\Core.mdpe', 
...XMIResourceImpl@1505ddb uri='file:/C:\Users\Sebastian\Desktop\WinesellerAnnotaions\Parameter.mdpe',

...XMIResourceImpl@1c3bff2 uri='file:/E:\01Test\ToolIntegration\runtime\Configuration\.metadata\.plugins\org.modelplex.mdpe.workbench.core\preTIPM.tipm', 
...ToolResource@6ed4db uri='file:/E:\01Test\ToolIntegration\runtime\Configuration\.metadata\.plugins\org.modelplex.mdpe.workbench.core\source2preTIPM.trace', 
...XMIResourceImpl@1c5274d uri='file:/E:/01Test/ToolIntegration/runtime/Configuration/.metadata/.plugins/org.modelplex.mdpe.workbench.core/TIPM.tipm', 
...ToolResource@125b20a uri='file:/E:/01Test/ToolIntegration/runtime/Configuration/.metadata/.plugins/org.modelplex.mdpe.workbench.core/Dev2TIPM.trace', 
...XMIResourceImpl@1cbedaf uri='file:/E:/01Test/ToolIntegration/runtime/Configuration/.metadata/.plugins/org.modelplex.mdpe.workbench.core/TIPM.tipm', 
...ToolResource@161b165 uri='file:/E:/01Test/ToolIntegration/runtime/Configuration/.metadata/.plugins/org.modelplex.mdpe.workbench.core/Dev2TIPM.trace', 
...XMIResourceImpl@1ce9e4d uri='file:/Core.mdpe', ]



The interesting point is the last entry in the ResourceSet with uri file:/Core.mdpe, which is not a valid file.

If I use ATL 3.0.0 this invalid file does not occur (see the resource set before and after the transformation.

Any ideas?
