Declarative Control Over Individual Page Life Cycle

Refresh="ifNeeded": Any change to a task flow binding parameter value causes the ADF region to refresh. There are no values other than ifNeeded for the Refresh attribute.

RefreshCondition="#{EL.expression}": The ADF region is refreshed a single time when its RefreshCondition evaluates to true. The RefreshCondition must evaluate to a Boolean value. At the time the RefreshCondition is evaluated, if the bindings variable is used within the EL expression, the context refers to the binding container of the parent page, not the page fragment displayed within the ADF Region. RefreshCondition is independent of the change of value of the binding parameters. If the task flow binding parameters do not change, nothing within the ADF region changes.
