Modifying semantic element starting from an IMarker [message #1754734]

Hi,

I am trying to bridge Epsilon's EVL with Sirius so that the former can be used to define constraints and quick fixes for diagrams constructed with the latter (similarly to [1]). I'm almost there but I'm having trouble implementing quick fixes, hence this post.

Assuming that I've got hold of a Sirius (org.eclipse.sirius.diagram.ui.diagnostic) problem marker (org.eclipse.core.resources.IMarker) with the following attributes, how can I run code that modifies features of its underlying semantic element (e.g. if the semantic element is a Person, change its name from X to Y)?

elementId -> _shUpEPd-EeadXOjn8SEqIQ
severity -> 2
DIAGRAM_URI -> platform:/resource/basicfamily.sample/representations.aird#_sg7ngfd-EeadXOjn8SEqIQ
org.eclipse.ui.editorID -> org.eclipse.sirius.diagram.ui.part.SiriusDiagramEditorID
location -> lola::<Man>
SEMANTIC_URI -> platform:/resource/basicfamily.sample/example.basicfamily#//@members.10
message -> Invariant Grumpy failed for Man [name=, ]

Cheers,
Dimitris

Hi again,

To refine my question, I suspect that I need to access 1) the semantic element (EObject) behind the marker and 2) its (Transactional?)EditingDomain so that I can run the modification code through its CommandStack. Any advice on how to get hold of these would be appreciated.

Cheers,
Dimitris

Hi Dimitris,

You can find how Sirius manages those markers and attributes to retrieve the element or the editing domain:
. org.eclipse.sirius.diagram.ui.internal.providers.SiriusValidationDecoratorProvider.StatusDecorator.refresh()
. org.eclipse.sirius.diagram.ui.internal.quickfix.ValidationFixResolution.getMarkedView(Session, IMarker)

Note that you could also define validation rules and quick fixes directly in your modeler specification model (see blog post http://melb.enix.org/sirius/validation/)

Regards,
