Hello everyone, do you know if there is a way to express the corresponding syntax of "load resource" in an emf model described with flexmi?

What I do with emf model editor is:
-load resource and I load another "emf model" so I can select an instance of the loaded model.

Is there a way to do it in a flexmi file?

Hi Ludovico,

Yes, this is possible. Please see the import processing instruction, which also works for non-Flexmi models (I'll update the docs shortly). I've also pushed a minimal example that demonstrates this but you'll need to update to the latest interim version of Epsilon for the Flexmi editor to work with importing non-Flexmi models.

Thanks,
Dimitris

Dear Dimitris, I'm processing flexmi models from standalone java code but it seems that the editor resolves the crossreferences between the model and the imported one. Instead if I launch a EVL script from standalone code I can't resolve cross references. Is there any instruction I should set in my java code?
I have already set mymodel.setExpand(true); but it is still unresolved. Moreover I have passed the referenced model as additional emf model to the evl script. Any idea?

Hi Ludovico,

Could you please share a minimal example I can use to reproduce the behaviour you're encountering?

Thanks,
Dimitris

Sure. Basically I'm reusing EpsilonLiveFunction class since I'm executing that code as a service, but also running the main locally does not work. If you execute the validate.evl with runtimeconfiguration you'll see that the console prints the "implements" list. If you execute it from Java it is empty, while the model myA refers to an imported flexmi file.
Thanks for the help!

Hi Ludovico,

The Flexmi parser tries to resolve the relative ?import: ra.flexmi import against the artificial "flexmi.flexmi" URI in your getInMemoryFlexmiModel() method and therefore fails.

On an unrelated note, as you are parsing the Emfatic text twice (once for each model), this produces two different copies of the same EPackage (metamodel), which is likely to cause other issues down the line.

Thanks,
Dimitris

You're right about the metamodel. Actually they were 2 separated metamodels that i decided to merge, so I can reuse the first loaded one.
Concerning the first problem, I need to import an existing flexmi on the server side. So the first flexmi is passed as string but the second one must be loaded when the serviceImpl is called. I'm getting confused :d
