Start events

For a process model to be executable, it must always contain at least one start event and one end event. A start event indicates where a process starts.

Start event

This is an untyped start event. You would use this event when there are no pre-conditions for the process.

Attributes: General

Attribute Description
Model ID The unique identifier of the element within the process model.
Name The name of the element displayed in the diagram.
Documentation A description and any additional information about this element.

Attributes: Details

Attribute Description
Initiator variable The variable that represents the default user who initiated the process.
Start form reference Reference of the form that will be displayed when a new process is created.
Form properties Custom form properties which are used within the legacy or custom form engine.

Attributes: Execution

Attribute Description
Asynchronous When enabled, the activity starts as an asynchronous job.
Execution listeners

Allows you to invoke Java logic after certain events:

  • Start: Executes after the activity has been started.
  • End: Executes after the activity was completed.
  • Transition: When defined on a sequence flow, executes once the flow is transition is taken.

Attributes: Visuals

Attribute Description
Font color The font color of the element in the diagram.
Font size The font size of the element in the diagram.
Font style The font style of the element in the diagram.
Font weight The font weight of the element in the diagram.
Background color The background color of the element in the diagram.
Border color The border color of the element in the diagram.

Timer start event

This event is used when a process is started on cyclic timer events either at specific points in time, after time spans or after timeouts.

Attributes: General

Attribute Description
Model ID The unique identifier of the element within the process model.
Name The name of the element displayed in the diagram.
Documentation A description and any additional information about this element.

Attributes: Details

Attribute Description
Timer properties Configure the time of the event.
Interrupting Determines whether the parent executions will be terminated.

Attributes: Execution

Attribute Description

Allows you to invoke Java logic after certain events:

  • Start: Executes after the activity has been started.
  • End: Executes after the activity was completed.
  • Transition: When defined on a sequence flow, executes once the flow is transition is taken.

Font weight The font weight of the element in the diagram.
Background color The background color of the element in the diagram.
Border color The border color of the element in the diagram.

Signal start event

This event is used when a process is started based on signaling from a different process. A single thrown signal can be caught multiple times by different catching signal events.

Attributes: General

Attribute Description
Model ID The unique identifier of the element within the process model.
Name The name of the element displayed in the diagram.
Documentation A description and any additional information about this element.

Attribute Description
Signal reference A reference from the signal definitions of the root model.
Signal expression An expression resolving to a signal name without needing
Interrupting Determines whether the parent executions will be terminated.

Attributes: Execution

Border color The border color of the element in the diagram.

Error start event

This event catches named errors. This event is only used inside of an event sub-process.

Attributes: General

Attribute Description
Model ID The unique identifier of the element within the process model.
Name The name of the element displayed in the diagram.
