In Oracle JDeveloper 11g, the change event policy feature can be used to refresh UI components
automatically that are bound to an ADF binding when data has changed in the model layer. To
use this feature, you set the ChangeEventPolicy property of the ADF iterator binding and the
attribute bindings to ppr, which also is the default setting.
In pagebinding select Iterator | in properties- Advanced - Change Event Policy : select value "ppr". What will happen is the moment you select a record in table other respective attributes on UI which were pointing to individual attributes from this iterator will display the new values else not.
