public class ActionsTag

extends javax.servlet.jsp.tagext.BodyTagSupport

JSP custom tag that renders an "instant actions" control. To the user, it appears as an HTML <select> element (i.e. a combo box), with the behavior of selecting a new page for the current frame or window when a different option is selected, without requiring a submit action. This tag has the following user-settable attributes:

• size - (Integer) number of rows that will be visible to the user. If not specified, one row will be visible.
• style - The CSS style class to be applied to the entire rendered output of the instant actions control, if any.

FIXME - Internationalize the exception messages!
