Specific Attributes

Name	Value Type	Default Value	Description	Comment	V.	Exp.
event_id	event id	Empty	Identifier of the event that triggers the action.	Mandatory	2.0	No
action_id	action id	Empty	Identifier of the target action to be executed when the event is fired.		2.0	No
script	script	empty	Script to be executed when the event is fired. Replaces action_id if present.		2.0	No
condition_formula	Math Formula	empty	Mathematical formula used as a condition to execute the action (can reference any object defined in the model). The action is executed only if the formula does not return 0.	Be careful with condition formulas when using synchronous execution as the data referenced in the formula may have not been updated yet.	2.0	No
async	boolean	'false'	When true, both the action and conditions are triggered asynchronously. When false, the condition is evaluated and the action is executed synchronously, as soon as the event is triggered.	Using synchronous trigger may cause the action to be executed while parts of the data model depending on the source event has not been entirely updated. On the other hand, asynchronous trigger will happen later, so the condition may have changed (if relying for example on the state of another action).	2.0	No
