[henshin-dev] Free parameters not defined when using multi-nodes 
Hi all,

I am experiencing problems with rule parameters in multi nodes. I cannot
use free parameters when I have multi-nodes.


I made an exemplary case with an exogenous transformation where I need to
convert between different name formats. Without multi-nodes the rule
works. When I use multi-nodes, I get

"Exception in thread "main" java.lang.RuntimeException:

To show my case I attached the example eclipse project to this mail.

Do I use the multi-nodes incorrectly?

Best regards
Marco
