Turnstile workflow activity

The Turnstile activity limits how many times a workflow can pass through the same point.

Use this activity to prevent infinite loops. This activity is useful alongside the Rollback To workflow activity activity.

Results

You can assign a result value using the activity.result variable from within a script field of the activity. By default, the activity script evaluates if the activity should continue to iterate or stop.

Table 1. Turnstile activity results
Result	Description
Continue	The Allowed iterations value is greater than the number of times the workflow accessed this activity.
Cancel	The workflow accessed this activity more times than the Allowed iterations value.

Input variables

Input variables determine the initial behavior of the activity.

Table 2. Turnstile activity input variables
Field	Description
Allowed iterations	Number of times the workflow can pass through this activity before the turnstile ends the loop.

Conditions

The conditions determine which transition comes after this activity.

Table 3. Turnstile activity conditions
Field	Description
Continue	If the workflow has returned to this point an amount of times less than the allowed iteration.
Cancel	If the workflow has returned to this point an amount of times more than the allowed iteration.

States

The activity state tells the workflow engine what to do with the activity.

Table 4. Turnstile activity states
State	Description
Executing	The workflow engine knows to start the onExecute function of the activity.
Waiting	The workflow engine ignores the activity until a specific event to restart the activity is triggered.
Finished	The activity finished running. See the result value for the outcome of the activity.
Cancelled	This activity, or the workflow that contains this activity, was canceled.
Error	A JavaScript error occurred. Review the logs for error details.
