public class WOFormValueTag

extends javax.servlet.jsp.tagext.TagSupport

This is a sub-tag of WODirectActionTag used to pass form values. WebObjects supports the use of DirectActions in JSP through the use of a Tag Library. While WODirectActionTag specifies the DirectAction that is used in a JSP, this specifies the key-value pair to be passed to the Direct Action as a form value in a query string. This tag has no body but has the following attributes:

• key. The key of the binding. Required.
• value. The value of the binding. Required.
