4. Select and then drag-and-drop the Task Flow Return acivity from the component
palete to the task low.

5. Name the Task Flow Return acivity as return .

What just happened?
In the previous acion, we have seen how the task low will return to its calling acivity.
The task low return acivity will have the following opions available:

Reentry : This atribute will represent whether the re-entry is allowed for the task
low or not. The available opions are reentry-allowed and reentry-not-allowed .
End Transacion : commit and rollback opions are available for the task low to
commit or rollback the transacion to the database. This is available if the task lows
are conigured to always require an exising transacion. Transacion opions in the
task flow will be covered later in this chapter.
Restore Save point : When this is set to true , this opion will help to restore the state
of the task low upon entering next ime to the point when it exited the last ime.

Parent Action
We know that a task low can be added to a page as a region. A region will be a secion in the
page which acts as a placeholder for the task flow. In an ADF region, if the bounded task flow
needs to trigger navigaion, then we would see Parent Acion . The outcome will be used to
navigate the task flow containing Parent Acion instead of navigaing the task low of the
ADF region. The opions available are as follows:

Parent Outcome : This will allow the outcome to navigate the parent acion to the
parent view acivity. It allows the region to force navigaion in the parent task low.
It is the immediate view owning the region.
