Hello all,
I used a custom decorateView method at <Connection>ViewFactory to have
Rectilinear Routing as default, but after an update I cannot.

How should I proceed?

Thanks in advance

Hi Ugo,
You can modify the routing style directly in your connection's EditPart.
Here is an example :

/**
* @generated NOT
*/
protected Connection createConnectionFigure() {
	ConnectionFigure figure = new ConnectionFigure();
	RoutingStyle style = (RoutingStyle) ((View) getModel()).getStyle(NotationPackage.Literals.ROUTING_STYLE);
	style.setRouting(Routing.RECTILINEAR_LITERAL);
	return figure;
}

i'd finally came across a solution, here is how i did:

protected Connection createConnectionFigure() {
ConnectionFigure figure = new ConnectionFigure();

AbstractEMFOperation emfOp = new AbstractEMFOperation(getEditingDomain(), "line routing setting") {
@Override
protected IStatus doExecute(IProgressMonitor monitor, IAdaptable info) throws ExecutionException {
RoutingStyle style = (RoutingStyle) ((View) getModel()).getStyle(NotationPackage.Literals.ROUTING_STYLE) ;
style.setRouting(Routing.RECTILINEAR_LITERAL);
return Status.OK_STATUS;
}
};

try {
OperationHistoryFactory.getOperationHistory().execute(emfOp, null, null);
} catch (ExecutionException e) {}

return figure;
}

Enjoy!

I tried the proposed "final" solution but I still get an Illegal State exception. Mine however is that "Can not activate read/write transaction in read-only transaction context"

Any ideas?
