About State and Status Transition Mapping

Using the Task editor Response Data tab, you can configure state and status transitions for completion events and exceptions returned by the activation system. You can define multiple transitions (each with an XPath expression) to model different scenarios for variations in the response data. For example, if an ASAP or IP Service Activator parameter returns the value DSL, you may want the task to transition to a DSL task; when the same parameter returns the value VOIP, you want the task to transition a different task.

You can define state transitions for user-defined states only. You cannot define transitions for system states, such as received, accepted, and completed. You define the condition in the Properties views. At run time, OSM evaluates the conditions in the order you have defined them and stops evaluating when a condition evaluates to true.

Completion events and exceptions must include a default transition in the event that all specified conditions fail. You can change or delete the predefined default values, or you can create your own. You can change or delete the predefined default values or you can create your own. If you define no default conditions for the required completion events and exceptions (no condition is defined with XPath expression true()) Design Studio creates a problem marker.

The following table lists completion events and exceptions that require a default transition configuration:
