Which two are reasons why you might set the bind variables of a view object at run time programmatically rather than using the declarative features of the framework? (Choose two.)

  1. The framework can set only one bind variable declaratively on each view object query. Attempting to set more bind variables requires a programmatic solution.

  2. After a bind variable is set using the declarative method, its value is immutable unless updated programmatically.

  3. In all cases, ADF developers should code solutions rather than using declarative solutions

  4. The bind variable is derived by calling a Java method rather than receiving the value from a user.

  5. The bind variable value entered by and understandable by a user must be modified using Java code to a value that can actually be used in a query.

Answer: B,D

  2. Create a page template that defines the specified layout and distribute it to developers

  3. Create an ADF library that contains a collection of ADF Faces components that developers must use

  4. Create a task flow template that defines the specified layout; this will enforce the correct layout on all pages that are built from the template.

  3. Two separate view object instances exposed through the application module allow you to apply separate view criteria and bind variable values to

    show separate result sets.

  4. Under the relating AppModuleDataControl in the JDeveloper Data Controls window, each view object instance appears as a separate selectable

    data collection
