Defining Time Constraints of a TaskLocate this document in the navigation structure


Time constraints refer to the activation, start, completion and expiration time of the task. You can define these times and deadlines by one of the following options:

  • Use a fixed reference time and an offset.

  • Use an expression to evaluate absolute time of type xsd:dateTime.


If you use context nodes in your expression from different namespaces with equal names, you have to declare the namespaces of these nodes. To solve the name conflict you can define a name prefix for the namespace. This declaration has the following syntax: xmlns:<prefix_name>="namespace_name" .

You can make the task raise critical exception when a start or completion deadline is reached.
