Re: [henshin-dev] Question about Henshins wrap model and GUI

Indeed, there is no special syntax for the wrapper model in the moment.
If it helps: there are two examples (generic copy & metamodel evolution)
in the examples plugin. The copy example you can also find on the web.
Oh, thats no problem for me; I'm currently just asking myself to what extent it makes sense to me to migrate my current approach realizing dynamic types to the wrapper model.
I am trying to test the wrapper model and built a simple UML model as well as a transformation unit the traditional way and as a wrapper (see attachements).
The unit "testrule_orig" does have a match at the original model as expected, but "testrule_wrap" does not have a match at the wrapped model.
However, there seems to be a problem when generating the wrapped model. When I generate the wrapped model, the map contained in the variable graph has about 17000 entries, although wrappers contains only 14. 

What am I doing wrong?

Thanks in advance,

Jens
