Hi,
I have a class ClassA with an attribute color:String in my domain
model. Now I'd like to update the background color of the nodes
representing instances of ClassA based on the color property. I did not
find anything in the graph/mapping models, so I guess I need to code it
manually. Can anyone give me a hint at what classes I need to look and
how I could possibly achieve what I want?
Many thanks!
Best regards,
Marc Moser

Does anyone know if this is the "right" way to do it?

@Ivar, Thank you for you replay 
In my model, there is an int attribute called TIRER, the background color of the NODE will be changed dynamically according the value of TIRER (0: balck; 1: red).
In XXXEditPart.java, I write a new function called ChangeColor
protected void ChangeColor()
{
int tirer = this.tirer;
Color backgroundColor;
switch (tirer)
{
case 1:
backgroundColor = ColorConstants.red;
break;
case 0:
backgroundColor = ColorConstants.gray;
break;
default:
backgroundColor = ColorConstants.gray;
};
View notationView = getNotationView();
EObject element = notationView.getElement();
if(element instanceof TransitionEditPart)
{
TransitionEditPart transitionEditPart = (TransitionEditPart) element;
}
setBackgroundColor(backgroundColor);
After that, I override the function handleNotificationEvent.
protected void handleNotificationEvent(Notification event)
{
super.handleNotificationEvent(event);
this.ChangeColor();
}
It works for me every time when I change everything of the node (position, name, etc). Right now, I hope that it change its background color in no time only when the value of TIRER is changed.
Do you have any idea? Thanks;)
Best Regards,
Vincent

Hi again,
did you try to override isAffectingEvent in your
class which extends AbstractParser?
AbstractParser.isAffectingEvent(Object, int)
Best,
