Re: [henshin-user] Nested application conditions in Henshin diagrams?

Thanks, Matthias. I have implemented this for my metamodel and it seems to work. The only strange thing at the moment is that the rule seems to remove all tokens from all input places rather than just one token per place. Clearly, I have a misunderstanding of multi-rules here. Can you help?

BTW, how does one get the textual syntax?

Many thanks,

Steffen

i think it is not possible with the graphical editor, so either use the tree (which i did for these use case, see attachement) or the textual editor.
