Hi,
I've eclipse Ganymede with GMF, EMF, EuGENia... lastest plugins. I've
tried to lunch an EuGENia project, but when I try to "Generate GMF tool,
graph and map models", I get the follow internal error trace:

org.eclipse.swt.SWTException: Invalid thread access

at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

Any idea?

Thanks.

Hi Jose,

Could you please attach your annotated ECore metamodel so that I can try
to reproduce the problem?

Cheers,
Dimitrios

This is my simple ecore model:

<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
xmi:id="_kYgXoMK0Ed2Sc7hIeGvFPw" name="eugeniasample"
nsURI="http://eugeniasample" nsPrefix="http://eugeniasample">
<eClassifiers xsi:type="ecore:EClass" xmi:id="_9SqSoMK1Ed2Sc7hIeGvFPw"
name="ClassDiagram">
<eStructuralFeatures xsi:type="ecore:EReference"
xmi:id="_9SqSocK1Ed2Sc7hIeGvFPw" name="composition" upperBound="-1"
eType="_9SqSosK1Ed2Sc7hIeGvFPw" containment="true"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" xmi:id="_9SqSosK1Ed2Sc7hIeGvFPw"

<eStructuralFeatures xsi:type="ecore:EAttribute"
xmi:id="_9SqSo8K1Ed2Sc7hIeGvFPw" name="name">
<eType xsi:type="ecore:EDataType"
href="http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</eStructuralFeatures>
<eStructuralFeatures xsi:type="ecore:EReference"
xmi:id="_9SqSpcK1Ed2Sc7hIeGvFPw" name="children" upperBound="-1"
eType="_9SqSosK1Ed2Sc7hIeGvFPw" containment="true"/>
<eStructuralFeatures xsi:type="ecore:EReference"
xmi:id="_9SqSp8K1Ed2Sc7hIeGvFPw" name="father"
eType="_9SqSosK1Ed2Sc7hIeGvFPw"/>
</eClassifiers>
</ecore:EPackage>

It's a tree structure model.

The emfatic sample post in the main project page give me the same error
(deleting tags that shows errors like the @gm or @compartment). A first
valid preview was:

@namespace(
uri="filesystem",
prefix="filesystem")
package filesystem;

class Filesystem {
val Drive[*] drives;
val Sync[*] syncs;
}
class Drive extends Folder {
}
class Folder extends File {
val File[*] contents;
}
class Shortcut extends File {
@gmf.link(target.decoration="arrow", style="dash")
ref File target;
}
@gmf.link(source="source", target="target", style="dot", width="2")
class Sync {
ref File source;
ref File target;
}
@gmf.node(label = "name")
class File {
attr String name;
}

Thanks.

Hi Jose,

Your metamodel doesn't have any GMF-specific annotations and therefore
Eugenia can't generate anything out of it (of course even in this case
it should fail more gracefully but this is another issue which I will
look into shortly). Similarly, the annotations you've removed from the
filesystem metamodel are also essential.

You mentioned that you have deleted those annotations because they were
highlighted as erroneous. I suspect this has to do with the version of
Emfatic you are using (the latest version doesn't support detail-less
annotations - but this should be fixed soon). To overcome this issue
please do not delete the annotations but instead add a dummy detail so
that Emfatic doesn't complain any more. For example:

@gmf.diagram(dummy="dummyValue")
class Filesystem {
val Drive[*] drives;
val Sync[*] syncs;
}

Cheers,
Dimitris
