Hello!
So I'm having problems with my project (again). I'm working with both Xtext and Sirius, so I don't really know where the problem lies. The thing is that when working with both syntaxes at the same time there are certain objects that return an error (see below) when being added from Sirius. It doesn't happen when adding those objects from Xtext, they just pop up in the graphical syntax as usual. Those objects are the ones inheriting from abstract classes (my workspace: https://www.dropbox.com/s/hgamlrayc4ymjlz/workspace.zip?dl=0). However, only one of the objects gives an error when specified in Sirius. In my grammar it would be the object Event, but not Action (also "ordered locations" but not "not ordered locations"). I realized that the order in the grammar is important since if I exchange (for instance) the position of events and actions the object returning error also changes. I hope I could explain it properly. Thank you in advance.
Best regards,
Sergio
