Compilation error for expression XYZ, headless mode [message #1706296]

Hello,

i have a problem with generating an SVG file of a Diagram in headless mode (console version of eclipse). I've loaded the "aird" resource, the semantic model resource but during the running of the following code line

DRepresentation representation = dialectManager.createRepresentation("ProcessDiagram", eObject,
repDescription, session, new NullProgressMonitor());

I get a bunch of errors of the following pattern:

Compilation error for expression [self.XYZ()/] : Cannot find operation (XYZ()) for the type (ABC)

for example:

!MESSAGE Compilation error for expression [self.getActions()/] : Cannot find operation (getActions()) for the type (Process)

In normal Eclipse Workbench it is working, it could find the Methods. Do i have to do something special for the programmatic way of generating the diagram?

Thanks in advance.

Best regards
m.emin

Hi,

I need more details to help you. Then some questions :
- Which release of Sirius do you use?
- Can you show the code you execute to do SVG diagram export
programmatically in headless?
- Do you have the XYZ(), getActions() operation and the ABC, Process
EClasses in your classpath?
- If the previous XYZ(), getActions() operations are java services, you
can try service interpreter [1] instead of using Acceleo 3.

the version i am using is 2 (qualified 2.0.0.201410241344).

final RepresentationDescription repDescription = representationDescription;
editingDomain.getCommandStack().execute(new RecordingCommand(editingDomain) {

	@Override
	protected void doExecute() {
		dAnalysisImpl.getModels().add(eObject);
		dAnalysisImpl.getSelectedViews().add(representationContainer);
					
		// Attach eObject to session see https://www.eclipse.org/forums/index.php/t/1068187/
		eObject.eAdapters().add(new SessionTransientAttachment(session));  // experimentally..

		DRepresentation representation = dialectManager.createRepresentation("ProcessDiagram", eObject, repDescription, session, new NullProgressMonitor());
		representationContainer.getOwnedRepresentations().add(representation);
	}
});

DRepresentation representation = representationContainer.getOwnedRepresentations().get(0); // experimentally..
DialectUIManager.INSTANCE.export(representation, session, Path.fromOSString(path + "testfile.svg"), new ExportFormat(ExportDocumentFormat.NONE, ImageFileFormat.SVG), new NullProgressMonitor());

Like i've tried to describe, it currently even can't generate the diagram. The exceptions are thrown in the line

DRepresentation representation = dialectManager.createRepresentation("ProcessDiagram", eObject, repDescription, session, new NullProgressMonitor());
		representationContainer.getOwnedRepresentations().add(representation);

---- EDIT:

All needed bundles are listed as required bundles in my plugins dependencies.

The update to sirius 3 caused dependency problems to other bundles that i need. So i reverted the update. I've also cleaned up the model, so it doesn't uses any acceleo expressions nor java services..

It fails now during the image generation in the following line

DialectUIManager.INSTANCE.export(representation, session, Path.fromOSString("C:\\Users\\mkaraman\\Desktop\\testfile.svg"), new ExportFormat(
					ExportDocumentFormat.NONE, ImageFileFormat.SVG), new NullProgressMonitor());

How can i reach that the OffscreenEditPart will be used to generate it in headless mode, or are there any other ways to generate image in headless mode?

Hi,

Your snippet code seems correct and it uses already OffscreenEditPart in
headless. Can you give more details on the failure?

Best Regards.

I think it didn't used the OffscreenEditPart.. so i have created the OffscreenEditPart with the help of its factory in the following way:

OffscreenEditPartFactory instance = OffscreenEditPartFactory.getInstance();
Shell shell = new Shell();
shell.open();

DiagramEditPart editPart = instance.createDiagramEditPart(diagram, shell);
layoutEditPart(editPart);
CopyToImageUtil copyImageUtil = new CopyToImageUtil();
copyImageUtil.copyToImage(editPart, Path.fromOSString(path + "testfile.svg"), ImageFileFormat.SVG, new NullProgressMonitor());
shell.dispose();

In this way it worked. Thank you for your help.

The problem with the expressions still appear. I found that the service class in the headless mode doesn't get load.. i am watching for breakpoint hits on the ServiceInterpreter's registerServiceClass and registerService methods, they get called in the normal runtime mode, but in headless mode these methods didn't get called. Is this a bug or do i have to trigger something manually?

By headless, you mean that your example is executed in OSGI environment?
There are some improvements on service interpreter with Sirius 3.0, what
are the dependencies issues you have when using Sirius 3.0?

Best Regards.

Xtext 2.8.3 is what i need and during the update of Sirius eclipse wanted me to update xtext to 2.8.4.

Yes, with headless mode i mean a console version of eclipse, without the workbench ui..

I've found the problem and could solve it. For all others hwo encounter the same problem: I had to load the project bundle and trigger the import loading,

final IInterpreter interpreter = SiriusPlugin.getDefault().getInterpreterRegistry().getInterpreter(eObject);
interpreter.setProperty("files", Collections.singletonList("/" + PLUGIN_ID + "/" PATH_TO_ODESIGN_FILE));
InterpreterRegistry.prepareImportsFromSession(interpreter, SessionManager.INSTANCE.getSession(eObject));
