Full quote An Activity may have more than one InitialNode. Next snippet If an Activity has more than one InitialNode, then invoking the Activity starts multiple concurrent control flows, one for each InitialNode. (Additional concurrent flows may begin at input ActivityParameterNodes and enabled ExecutableNodes ... An InitialNode shall not have any incoming ActivityEdges, which means the InitialNodes owned by an Activity will always be enabled when the Activity begins execution and a single control token is placed on each such InitialNode when Activity execution sta Related snippets Related snippets (backlinks) An InitialNode shall not have any incoming ActivityEdges, which means the InitialNodes owned by an Activity will always be enabled when the Activity begins execution and a single control token is placed on each such InitialNode when Activity execution sta The outgoing ActivityEdges of an InitialNode must all be ControlFlows. The control token placed on an InitialNode is offered concurrently on all outgoing ControlFlows. InitialNodes are an exception to the rule that ControlNodes cannot “hold” tokens, but only manage their flow. Visit also Visit also (backlinks) Flags
