Hi there,
I've been modeling a small graphical editor for a very small language
and until I tried to customize graphical appearance and behavior
everything was quite ok. Now that I try to add some new "features" I've
been adding some problems. The first one is that, after changing the
Figure of one of my classes from rectangle to Ellipse, two of the other
classes in the metamodel also got the Ellipse mapping.
My .gmgraph is as follows:
<?xml version="1.0" encoding="UTF-8"?>

</gmfgraph:Canvas>
As you can see, I've modified the Node Place to be an Ellipse instead of
a rectangle. Instead I also got InputArc and OutputArc as Ellipse. Any
idea why? (I'm also sending in attachment the .gmfmap file if it might
be useful).
My second question is related with grouping elements. In my metamodel
the following Associations:
InputArc -> Place
InputArc -> Transition
everything with 1-1 multiplicity. In my graphical editor I need to have
an arrow that goes directly from Place to Transition taking into account
that this arrow will be an instance of InputArc. For the moment, using
the default generated .gmfgraph and .gmfmap I MUST create the polyline
from InputArc to Place and from InputAr to Place (which correponds
exactly to the metamodel but it is not suitable for the graphical
editor). Any hint how to do this?
Thank you very, very much for your time and help.
All the best,
Luis Pedro

Hello Luis,
> the graphical editor). Any hint how to do this?
You can create LinkMapping for InputArc:
domainMetaElement = InputArc
sourceMetaFeature = reference InputArc -> Place
linkMetaFeature = reference InputArc -> Transition
containmentFeature = containment for InputArc
Then InputArc will be represented as a link on your diagram.
