Workflow Hooks

In this tab you can redefine sub flows by using Hooks. The function is for advanced users.

Hooks: Definition and Conditions

Workflow Hooks are the delimiters of sub flows. By redefining them you can make a Call Sub Flow node in a work flow call another sub flow than was originally intended to.

The Workflow Hooks tab displays a list of hooked sub flows that match the following conditions:
  • The sub flow must have been configured with a Hook Identifier.
  • The sub flow must be called by another work flow.
  • The sub flow must have run at least once.

Hooks: Redefining

For the process to be illustrated it requires the presence of 2 ready made flows, 1 work flow and one sub flow.

Build them following the topics Building a workflow, Start Sub Flow, Call Sub Flow and the instructions below:

  1. In the Workflow Editor, build a basic workflow as described in Building a workflow and configure it as the example image above my_workflow01. Start with a Start from Kiosk node and end it in an End node.
  2. Drag in a Call Sub Flow node. This will call the sub flow built in step 3 below.
  3. To integrate a sub flow, drag in the Start Sub Flow and Return From Sub Flow nodes.
  4. Configure the nodes as per example.

    Make sure to name the sub flow consistently in all node configuration dialog boxes.

  5. Click open Kiosk and Submit to run the workflow.
  6. In the Workflow Editor, build a sub flow, like in the example below my_test_hook. This will serve to substitute the first sub flow.

  7. Click the Manage Hooks button to open the Workflow Hooks tab.

    The hook is listed in the Workflow Hooks tab.

    Should the list be long and you cannot find the hook, you can use the quick search on top of the Workflow Hooks list to search them. If the query matches an entry name or a part of a name, the list is filtered by the matching hits and the hit is highlighted in yellow.

  8. Double click the hook line.

    The hook's details pane is displayed Save Workflow Hook.

  9. Enter the name of the second sub flow so as to point the main workflow to it.
  10. Click Save.

    When you now run the first workflow, you will see that the sub flow is skipped and the its nodes display hook marks.
