Summary
A state machine or a state cannot contain several states with the same name.
Details
The name of a state must be unique in the enclosing state machine or state. Showing the same name twice may cause confusion.
Tips
Possible solutions to this problem are as follows:
-
Solution 1
Rename one of the states that have the same name. This name must be unique in the enclosing state machine or state. -
Solution 2 Move one of the states that have the same name to a different enclosing state, which does not already contain a state with that name.
