This Specification Flow Task starts an application and will pass arguments into it on execution.
DriveWorks will pause/ wait while the application is running.
When the Task is executed it will either wait for the application to finish itself, or if the timeout is reached first then the Task will terminate the application.
The Task will execute on the host machine of the DriveWorks application from which it is being run.
For example:
If the Task is triggered from a client connected via DriveWorks Live, the Task will execute and attempt to run the application on the DriveWorks Live server machine.
Please take care to ensure the Task only executes the intended application, particularly when dynamic rules can result in different applications being started.
