## com.bea.netuix.servlets.controls.window.backing
Class WindowBackingContext

    java.lang.Object
      ControlContext
          com.bea.netuix.servlets.controls.BackingContext
              com.bea.netuix.servlets.controls.window.backing.WindowBackingContext

Direct Known Subclasses:
  PageBackingContext, PortletBackingContext

    public abstract class WindowBackingContext

extends BackingContext

This is the backing context class for a Window. Use this class when in a backing file to get information about the owning window. If you want to access this context from a JSP, look at WindowPresentationContext instead.

You can obtain the backing context for the active window by calling `BackingContext.getContextFromRequest`
