Hello,
In building a Higher-order Transformation which compiles an extended ATL model (let's call it ATL') to a normal ATL model, I am having a strange error. I basically know what line of code in my ATL' file triggers it, but I do not know what is wrong with it. Since the semantics is quite complex to explain, I just post the error I get.
Hopefully someone knows in which direction to look. I do not even know what the error means. So I need a starting point. If necessary, I will post more details about my HOT in a later reply.

I solved it. It had to with a helper that didn't create a certain element, while it should. I don't know exactly why and such, but it is solved.
I think this NOT creating some elements caused 'dangling' elements. Now normally this at least compiles, but maybe not for all cases?
