public class ScrollableModelTag

extends javax.servlet.jsp.tagext.TagSupport

This tag helps with the navigation of a scrollable model by outputting a "Previous | 20-29 | Next" text with the proper hyperlinks based on the attributes of the tag.
Those attributes are:

1. origin: the page from which this tag originates, for use by the WebFlow engine
2. event: the event from a WebFlow engine view
3. prevString: the JSP entered "Previous" in the language of choice
4. nextString: the JSP entered "Next" in the language of choice
5. pageIndex: the index of the page in the scrollable model one views.

The ScrollableModel is obtained from the pipeline session directly.
