[henshin-dev] mapping

[NA S <anoniems@xxxxxxxx>]

Hello again,

I've created a mapping ecore for marking purpose similar to the Ecore2GenModel example. Whenever I try to do the model transformation, I keep on getting error. The simplest way I did was to add a Marker class on the RHS which points to an object (for example State). When I deleted the Marker, it worked fine. But when I added it, I got an error: Exception in thread "main" java.lang.NullPointerException.

Is there something I'm missing here?

Thanks in advance.

Kind regards,
Amalia
