Reassigned Exception Handling Pattern

The following table highlights some important facts about the Reassigned Exception Handling Pattern:

Signature	Reassigned Exception Handling Pattern
Classification	Exception Pattern
Intent	The intention is to reassign the process token to the same activity on which the exception has occurred.
Motivation	When exception occurs, there would not be any change in the state of the process.
Applicability	A token is assigned to an activity. When the exception occurs, the token gets reassigned to the same activity. Hence, when the exception occurs, there would not be any change in the state of the process.
Implementation	Implementation is discussed as follows.
Known issues	NA
Known solution	NA

When we check the preceding process state diagram, we can notice that TBE is a timer event and a sequence line flows from the TBE back to the activity. Perform the following steps to realize the scenario and test it:
