Prerequisite: You should prepare a flow to bind with subFlow or Popup subFlow state. The flow bound with popup subFlow state must have:
▪ A final state named close.
▪ A transition name close linked to the final state.
A SubFlow or Popup SubFlow state is used to call another flow. Popup SubFlow only differs from SubFlow in using another popup window. They exist in a transaction flow as a referenced state.
The procedure in this topic describes the creation by using the SubFlow state icon or Popup subFlow state icon . If the flow that you want to bind has already been prepared, you can drag the flow from the Project Explorer pane to the editing area in the Transaction editor as shown below. The properties and events that have been configured in the flow are copied to the SubFlow state, and the name of the transaction file is displayed on the label of the SubFlow state.
