enum LinkNavigability {
bidirectional = 0;
unidirectional = 1;
}

@gmf.link(source="from",target="to")
abstract class Link extends Element{
attr LinkNavigability navigability;
ref InteractionPoint[1] from;
ref InteractionPoint[1] to;
ref Component fromContext;
ref Component toContext;
}

@gmf.link(target.decoration="rhomb")
class SABinding extends Link {
}

@gmf.link(target.decoration="arrow")
class SAChannel extends Link {
}

how can I create source.decoration where the attribute navigability has the value 0 (bidirectional)

thanks
marco

Hi Marco,

I believe that to update figures in response to changes to the
respective semantic elements, you need to modify the generated code.
Below is a link that appears to be relevant.

Not sure I can help any further with this one as it's clearly not a
EuGENia issue. If you need further help with this, I'd recommend posting
to the GMF forum.

Cheers,
Dimitris
