Link Button causes crash in some situations #809

Closed yourhead closed 5 years ago

yourhead commented 6 years ago

Still investigating what is special about this particular button setup. But the setValueForKey on the RW binding is crashing -- so I assume the other end of the binding has been deallocated.

seems clear that this is something isn't being defined and the link export in rw crashes. however i can no longer duplicate this. it's possible it was fixed inside rw.
