It looks like a facet query invoked by the Model Explorer caused proxy resolution, which loaded a resource containing UML-RT state machines that needed to be synchronized, but I can't tell from the exception trace which command was unexecutable (and certainly not why). Peter, could you possibly share your model with me? Off-line, if necessary.
I am not sure which model this happened in (I used the automated error reporting to submit several errors that I bumped into). There is a rather high probability that this happened in one of our larger models, in which case it will be hard to provide the model. I will keep an eye on this one and see if I get it to repeat in a smaller example model that should be possible to provide.
I have this repeatable in one of our large models, and I have tried to get it repeatable in a smaller example model, but failed to get it to repeat. But it seem to have to do with the case with capsule inheritance and the synchronization of the state machines. I am really not sure what to expect at the moment, but it looks like too much is being synchronized. In one model where I can get it to repeat I actually also get a case of duplicated state-machines. But I guess that there are work left to be done specifically for the Papyrus-RT tooling to get everything to work as expected. Just wanted to let you know. I will see if I can get the time to try this out a bit more and see if I can get a repeatable test-case. The larger model is unfortunately not possible to pass on.
(In reply to Peter Cigéhn from comment #3) Following this one up, I noticed last month that something has happened to pretty much completely break the capsule state-machine inheritance prototype, which I may want to take some time to look into. Also, not that this always was just a prototype: the intention being that the UML-RT team (who actually know how it's supposed to work) would take it as a starting point. But, I'm not sure where that leaves this particular bug, which to me doesn't seem actionable at this point.
Papyrus-RT is not using the SyncService.
