Re: JDeveloper 11g/ADF JPA/EJB form; Commit operation missing in Data Control? Posted: Jan 25, 2011 9:04 AM in response to: KenBray Helpful Reply Hi, Commit and Rollback is not available for DataControls other than ADF Business Components as there is no native semantic of commit / rollback. Instead the EJB facade exposes a method ("persist" for commit and "merge" for update) that you call to persist changes. So in ADF, what you do - drag the merge or persist method from the Data Control and drop it as a button - A dialog opens for you to point it to the object you want to save - Use Expression Builder (button next to the value field) and browse bindings --> Iterator name of form --> currentRow --> dataProvider Next time you press the button, the current row is persisted Frank Ps.: For a future release we are working on a mapping method in a session facade that allows us to map the Commit/Rollback operations directly
