Saving a file from the editor [message #723387]

Hello,

I've created a statechart editor and I did some customization similar to the GMF Mindmap Tutorial 3.

Basically when I right click the diagram, a model transformation is done, which is executed using Command. This seems to work except that I can't save the transformed diagram into another file. I've got an error: java.net.UnknownServiceException: protocol doesn't support output.

Any idea how to do this?

Here;s the code for Command:

protected Command createUnitApplicationCommand(final UnitApplication unitApplication, final EObject statechart) {
		
		return new AbstractCommand() {
			@Override
			public void execute() {
				boolean result = unitApplication.execute();
				if (result) {
					System.out.println("Successful");
					
					if (statechart == null) {
						System.err.println("statechart is null");
						return;
					} 

					Bundle bundle = Platform.getBundle("tue.examples.statechart");
					String path = bundle.getEntry("model/default2.sm").toExternalForm();
					URI modelUri = URI.createURI(path);
					statechart.eResource().setURI(modelUri);
					
					try {
						statechart.eResource().save(null);
					} catch (IOException e) {
						e.printStackTrace();
					}
				} else {
					System.err.println("Not successful");
				}
			}
		};

Amalia,

It looks like you're trying to save into contents of an installed
bundle, which of course isn't supported. What are you trying to
accomplish with the code you show below? An application that modifies
its own installation is a very bad idea. Shouldn't you be trying to
save to the workspace with a platform:/resource/<project>/<path> URI?

Hi Ed,

What I am trying to achieve is to save the result of model transformation into a file. I've tried the following, but it didn't save the file at all. Do you know how to save it into a file?

URI modelUri = URI.createFileURI(new File("D:/Documents/Eclipse/tue.examples.statechart.diagram.custom/model" + "statechart.henshin")
						.getAbsolutePath());
					Resource res = resourceSet.createResource(modelUri, "henshin");
					
					try {
						res.getContents().add(tsResult);
						res.save(null);
					} catch (IOException e) {
						e.printStackTrace();
					}

You've used the debugger to look at the value this produces. I.e.,
where are you looking to see if it's saved?

Does it thrown an exception? If so, what does it tell you?
