Flow Lifecycle
While navigating between flows, for example from flow-a to flow-b, the current flow for a page changes from flow-a to flow-b. When this change happens, two events notifying the change are dispatched: 1) flow-b is entered, then 2) flow-a is exited.
The following table describes the two flow events:
| Name | Description |
|---|---|
| vbEnter | Dispatched when entering a flow after all the flow scoped variables have been added and initialized. |
| vbExit | Dispatched when exiting a flow before disposing of flow resources. |
