In its simplest form, the Flow Chart Trigger simply waits for another workflow to finish before firing. For example, if workflow /ThisWorkflow needs to wait for /OtherWorkflow to finish before /ThisWorkflow can continue, a Flow Chart Trigger can be configured to meet that need.
In its full form, the Flow Chart Trigger can be configured to wait for an entire namespace of workflows to finish before firing.
The name of the workflow or group of workflows that must complete before this trigger will fire.
It is illegal to set a namespace of "/", since it implies there are no workflows in the entire cluster. Of course, if this Flow Chart Trigger is active, its workflow is in the cluster and this trigger could never fire.
Trigger waits until /OtherWorkflow finishes before firing.
Trigger waits until all workflows in the /eastcoast/ namespace finish before firing.
Trigger waits until /eastcoast/otherWorkflow finishes before firing.
Trigger waits until all workflows whose names start with /Inbound finish before firing.
