[Qt-interest] unable to use more than 1 transition added to a state (QT StateMachine Framework)

[Mandeep Sandhu]

On further debugging this problem I found that the issue is because of
attaching the same transition to more than 1 state.

Can't a transition be attached to more than 1 state?

Eg. If i define my transition as "On event E1, move to State S1"

I attach this transition to S3 and S6...now if an event E1 occurs
while the state machine is in S3 or S6, it should transition to S1.
Correct?

Or is this a bug in the state machine framework?

Thanks,
