Configuration Panel Settings

Edit the Element Name

An element name is a human-readable reference for a Process element. Process Modeler automatically assigns the name of a Process element with its element type. However, an element's name can be changed.
Follow these steps to edit the name for a Boundary Signal Event element:
  1. 1.
    Select the Boundary Signal Event element from the Process model in which to edit its name. Panels to configure this element display.
  2. 2.
    Expand the Configuration panel if it is not presently expanded. The Name setting displays. This is a required setting.
  3. 3.
    In the Name setting, edit the selected element's name and then press Enter.

Interrupt the Best-Case Scenario Workflow

Indicate whether the Boundary Signal Event element interrupts the best-case scenario workflow:
  • Interrupting workflow: When workflow routes through the Boundary Signal Event element, workflow is interrupted and does not route through the best-case scenario. As highlighted in the example below, workflow routes through the Boundary Signal Event element if the Boundary Signal Event element receives the specific broadcasting Signal for which it is listening if the Manual Task element is not complete when receiving that Signal.
  • Non-interrupting workflow: Workflow routes both through the Boundary Signal Event element and the best-case scenario, thereby creating parallel workflow in that Request. As highlighted in the example below, workflow routes through the Boundary Signal Event element if the Manual Task element is not yet complete; however, workflow also routes through the best-case scenario when that element completes.
Follow these steps to indicate if this Boundary Signal Event element interrupts the best-case scenario workflow when it triggers:
  1. 1.
    Select the Boundary Signal Event element from the Process model in which to indicate if it interrupts the best-case scenario workflow. Panels to configure this element display.
  2. 2.
    Expand the Configuration panel if it is not presently expanded, and then locate the Interrupting setting.
  3. 3.
    From the Interrupting checkbox, indicate whether this Boundary Signal Event element interrupts the best-case scenario workflow when it triggers. When the Interrupting checkbox is selected, which is the default setting, this element interrupts the best-case scenario workflow.

Select the Signal to Trigger the Element

A Boundary Signal Event element represents alternate workflow routing when that element receives a specific broadcasting Signal. The element that broadcasts the Signal does not need to be in the same Process model as the Boundary Signal Event element to receive the broadcasting Signal. Use a Boundary Signal Event element to design business solutions when alternate workflow must occur simultaneously across multiple Process Requests when a separate element in a separate Request broadcasts a Signal for which any or all Boundary Signal Event elements is listening. Select the Signal that triggers this element.
Follow these steps to select the Signal that triggers the Boundary Signal Event element:
  1. 1.
    Select the Boundary Signal Event element from the Process model in which to select the Signal that triggers it. Panels to configure this element display.
  2. 2.
    Expand the Configuration panel if it is not presently expanded, and then locate the Signal setting.
