public class ERXBatchNavigationBar
extends ERXStatelessComponent

Better batch navigation bar to page through display groups.

• User typing null for either number of objects per batch or the page number
• When resetting the number of items per batch the page first page displayed would be the last page.
• Broadcasts a notification when the batch size changes
• Has go first/go last methods
• Has option to not clear the selection when paging, which WODisplayGroup does when calling displayNext()/displayPrevious()
• Broadcasts a notification when the batch size changes
• Can be used inside or outside of a form
• Graphics can be easily configured
• Has localization support, both for static texts and the object count.
