I often don’t synchronize mine either, doing it manually gives you an extra degree of control.

There are some exceptions where the convenience of syncing overrides the norm.

Does it make sense to have a non-stateless non-synchronizing component? My rule-of-thumb has always been stateless+non-synchronizing or non-stateless-synchronizing. But it seems to be a 2x2 matrix.

There is no corresponding setter method like 'setProviderCanChangeStatusToSUBMITTED(boolean b)' because it's not necessary to store such a value. Nevertheless my app crashes complaining that there is no corresponding setter method (Stacktrace below). For testing I implemented an empty setter method: public void setProviderCanChangeStatusToSUBMITTED(boolean b) {} and then everything works fine. Any ideas why WO is trying to call this setter method?
