When constructable objects are added as part of a group object one has to call modified() manually on those objects (see comment). It seems it is pretty easy to do that automatically (but maybe I miss something). I'll try to provide a patch.
Sounds good!! I think we preferred manually for now since the modified calls can be expensive and we have to make sure to only call it when really required. Can't wait to see your patch :)
