Problem using EVL on a UML 2.1 meta-model? [message #502095]

Hi all,

I've been trying to write a simple EVL constraint for a UML 2.1 diagram. For this purpose I followed this tutorial http://www.eclipse.org/gmt/epsilon/doc/articles/evl-gmf-inte gration/ with slight changes:

First of all, the TIP written at the beginning of the tutorial recommends changing the .gmfgen model configuration if

Quote:

you have not implemented your editor using EuGENia

How do I change these configurations for a UML editor that wasn't implemented by me?

Step 3 - I'm using an EVL constraint which is compatible for the UML meta-model:

context Class {
	critique constraint1 {
		check {
			 'checked'.println();
			 return not(self.name = 'Foo');
		}			  
		message: "problem with class"
	fix { title: "DummyFix" do {} }
	}
}

and added its path to the binary build tab.

Step 4 - I've added the org.eclipse.epsilon.evl.emf.validation extension and created a new constraint binding in it with the following details:

namespaceURI: http://www.eclipse.org/uml2/3.0.0/UML
constraints: the path of the *.evl from Step 3

added the org.eclipse.ui.ide.markerResolution extension and created two markerResolutionGenerator with the following details:

class: org.eclipse.epsilon.evl.emf.validation.EvlMarkerResolutionGe nerator
markerType: org.eclipse.uml2.uml.editor.diagnostic

class: org.eclipse.epsilon.evl.emf.validation.EvlMarkerResolutionGe nerator
markerType: org.eclipse.emf.ecore.diagnostic

Now I opened a new eclipse instance, created in it a UML 2.1 class diagram, drew a class with the name "Foo", saved the diagram, clicked "Validate" and nothing happened (There was nothing new under the "Problems" view and no indication for a constraint violation was shown on the diargram).

What am I doing wrong?

Thanks

Hi Barak,

I've reproduced this. Could you please open a bugzilla to keep track of
this and post the link here?

Cheers,
Dimitris

Hi Barak,

Actually the bug should be filed under GMT/Epsilon, not GMF. I
understand all these TLAs can be confusing :) Could you please set the
bug to invalid and create a new one by following this link?

https://bugs.eclipse.org/bugs/enter_bug.cgi?product=GMT& component=Epsilon

Cheers,
Dimitris

Hi Barak,

On an update to this, the problem seems to be coming from the UML2Tools
side. More specifically, when validation is invoked, UML2Tools seem to
be overriding all other previously registered validators in
EValidator.Registry.INSTANCE with its built-in
org.eclipse.uml2.diagram.common.validation.UML2ToolsValidato r. I'll post
a question to the UML2Tools newsgroup shortly and see what happens...

Cheers,
Dimitris
