An exception handler is the central place for handling unexpected exceptions in an application. For example, a method activity defined in a task flow may throw some business or runtime exceptions when specific conditions are not met at runtime. ADF allows you to handle such erroneous scenarios in a more user friendly way by designating one activity in a bounded or unbounded task flow as an exception handler.
To mark an activity as an exception handler, right-click on the desired activity in the task flow and select Mark Activity | Exception Handler.
An exception handler can be specified for a bounded or unbounded task flow. At runtime, when an error is thrown from some activity inside a bounded task flow, the framework will navigate to the exception handler activity specified for the current task flow. If there is no exception handler specified for the current task flow, the framework will check its immediate parent task flow for an exception handler activity. This...
