Programatically open diagram of referenced model element [message #493776]

Hi all,

I want to open a diagram of a model element (say B) defined by an EReference of another model element (say A), which is appearing on the diagram. How can I do this?
I thought of two ways:

1. Assigning an Open Diagram Behaviour to the A edit part, and override its getOpenCommand() and OpenDiagramCommand#getDiagramDomainElement() methods to return the appropriate model element. But I don't know how to override the former: the diagram link style is queried from the A edit part's view. How do I get the correct diagram link style of the B edit part's view?
2. Assigning a Custom Behaviour to the A edit part with key of OpenRequest, and programatically open the diagram with the related B model element as diagram root. How can this be done?

Thanks in advance,
thSoft

Hello Dennis,

> How do I get the correct diagram link style of the B edit part's view?
((View) diagramFacet.eContainer()).getElement() will return underlying instance
of A element, so you can cast it to A and call .getB()
