[FYI] mikko.mononen Original CL Desc ----------------------------------------------------------------- StateTree: Fixed ID clash when duplicating transitions, plus misc editor fixes - Fix duplicate state - Fix creating new node IDs when a whole transitions is duplicated - Fixed state ID leaking into state names, when ID debug display is on - Fixed updating the state tree view when task type is changed [FYI] yoan.stamant [CL 26145814 by mikko mononen in 5.3 branch]
