After closing T2413 (Controlled initialization of EventMapper and StateMachines), I found a bug in StatemachineFactory. During buildup of statemachine patterns, method RParse never returns true. The bool value is used to check if the statemachine patterns are defined propperly.
After solving the bug, I found two statemachine patterns in statemachine.xml that are not consistent. (drag and dragWithCtrl). There are several states, that cannot be cheached, because the startstate never leaves itself via the transitions.
Thus statemachine.xml also was adapted.
