[news.eclipse.modeling.gmf] setroutingconstraint curve problem

[Kelvin Ng <kelvinng.db@xxxxxxxxx>]

Hi everyone,

I have a connector extends PolylineConnection rather than PolylineConnectionEx.
For all my other connectors, that extend PolylineConnectionEx, they 
curve smoothly after I call:

///////////////////////////////////////////
RoutingStyle style = (RoutingStyle) 
view.getStyle(NotationPackage.eINSTANCE.getRoutingStyle());
style.setSmoothness(org.eclipse.gmf.runtime.notation.Smoothness.NORMAL_LITERAL);
///////////////////////////////////////////

in 

their respective view factories, but for the one connector that extends 
PolylineConnection, it doesn't curve at all.

Now, I read that there still might be a way to curve it using routing 
constraints (setroutingconstraint)?
I can't seem to get the code right, and it's just not working properly. 
Can someone post an example of how it's done?

This is what I have so far:

///////////////////////////////////////////
public class DependencyLineConnection extends PolylineConnection {
........

protected void outlineShape(Graphics g) {
	.......

	ConnectionRouter connectionRouter = this.getConnectionRouter();
	ArrayList<AbsoluteBendpoint> list = new ArrayList<AbsoluteBendpoint>();
		
	list.add(new AbsoluteBendpoint(midPoint));
	this.setRoutingConstraint(list);
///////////////////////////////////////////

This doesn't work, and the line disappears. Any tips?
Thanks in advance.
