Must Have at Least Two State Names EWarning
DPL events must have at least two states. If an event has only two states and you attempt to delete one of them, DPL will not let you and will display a warning. If you only want the node to have one state, change the node into a value node. If you want to control a node to one state, see Branch Control/Block.
