Notes:


Binding Objects in the Executables Section

The following types of binding objects are available in the executables section:

iterator: Is the basic link from data to binding

methodIterator: Links the results of a method call to a binding

accessorIterator: Links to detail collections for nested objects (not used with ADF BC)

variableIterator: Accesses local data defined in the page definition file

Most often used for method arguments

Not linked to a data control

invokeAction: Allows the invocation of a method binding automatically within the life cycle (an alternative to invocation using a user action—for example, clicking a button). This type of binding was used in earlier versions of JDeveloper to invoke a method, but in the current version it is better to use a method call in a task flow, which gives you better control over when the method is executed.
