public class Token extends UIBean
Stop double-submission of forms.
The token tag is used to help with the "double click" submission problem. It is needed if you are using the TokenInterceptor or the TokenSessionInterceptor. The s:token tag merely places a hidden element that contains the unique token.
Examples
