Hello,
as part of learning GMF I'm coding a simplified UML Class Diagram
editor. Unfortunately, I've ran into the following problem:
I'm creating a PolygonDecoration that represents the arrowhead of a
generalization relation. The relevant part of the GMFGraph definition is
visible in the attached screenshot.
The problem is that the generator messes up the decoration definition
code severely:
private org.eclipse.draw2d.PolygonDecoration createTargetDecoration() {
org.eclipse.draw2d.PolygonDecoration df = new
org.eclipse.draw2d.PolygonDecoration();
// dispatchNext?
df.setFill(true);ERROR: org.eclipse.emf.codegen.jet.JETException:
InvocationTargetException
org.eclipse.draw2d.geometry.PointList pl = new
org.eclipse.draw2d.geometry.PointList();
pl.addPoint(0, 0);
pl.addPoint(-1, -2);
pl.addPoint(-1, 2);
df.setTemplate(pl);
df.setScale(getMapMode().DPtoLP(7), getMapMode().DPtoLP(3));
return df;
}
I suspect that this is a bug. Is there a possible workaround? Or, what
am I doing wrong?
Regards
PS. I'm using version 1.0.0.v20060627-1200 of GMF.

Hi,
I've submitted https://bugs.eclipse.org/bugs/show_bug.cgi?id=156702.
For now as a workaround, set the foreground color for connection rather than
for its decoration.
It will definitely work with almost the same visble results.
Regards,
Michael

Hi,
Also I ve found that you may fix it by just setting the name for your
decoration.
It does not seem reasonable to set the names for decorations, but they are
figures and as such generator assumes that they have names.
Its a pity that it is not validated prior to generation for now.
Regards,
Michael

Hello,
thanks for the help and for making the bug submission! Indeed, naming
the decoration has solved the problem.
