Introduction

List of values (LOV), bind variables and view criteria are essential elements related to view objects. They allow further refinements to the view object's query (bind variables and view criteria) and make the development of the frontend user interface easier when dealing with list controls (LOVs) and query-by-example (view criteria) components.

Many of the user interface aspects that deal with list controls and query-by-example components can be pre-defined in a set of default values via the UI Hints sections and pages in JDeveloper, thus providing a standard UI behavior. By using LOVs, for instance, we can pre-define a number of attributes for UI list components, such as the default UI list component, the attributes to be displayed, whether "No Selection" items will be included in the list, and others. These defaults can be overridden as needed for specific LOVs.

Bind variables and view criteria, usable in conjunction or separately, allow you to dynamically alter the view...
