Hi,

I tried to import an ecore from another project to an emf file, but still get an error "Failed to resolve type: PL". Here are both emf files:

pld.emf:

@namespace(
	uri="/org.model.variability/model/pld.ecore",
	prefix="")

package pld;

@gmf.diagram(onefile="true", diagram.extension="pld", model.extension="pld")
class PL{

  	unsettable attr EString name = "PL";
}

and hw.emf, located in another project:

@namespace(
	uri="/org.model.variability.hw/model/hw.ecore",
	prefix="")

package hw;

import "platform:/resource/org.model.variability/model/pld.ecore";

@gmf.node(label="name", label.icon="false", color="238,233,233", border.color="0,0,0", resizable="false")
class Platform{
  	unsettable attr EString name = "Platform";	
  	
  	ref PL pl;
}

Am I doing something wrong with my import?

Cheers,
Phil

Ok, it seems that the missing package name in front of the class is causing this. So using ref pld.PL pl; is accepted.

But when I try to generate an GMF editor with Eugenia, I get a NPE:

Hi Phil,

As discussed in [1], currently Eugenia only works with self-contained single-package metamodels.

Cheers,
Dimitris

Is there any support of metamodels that span across several files for the future planed?

Hi Phil,

I'm afraid there are no concrete plans for such an extension.

Cheers,
Dimitris
