How can I pass extra information on Submit button?

[Jerzy Kalat]

Hi,   I list many records on the form. Each record has 'Details' submit button, which suppose to flip form from 'List' mode to 'Details' mode, where only 1 record is visible with all it fields.   On my jsp page I have:     <logic:iterate id="element" type="myApp.common.GeoEntity" name="<%= Constants.GEO_ENTITY_LIST %>">  <table>         <tr>     <td>     <html:submit property="action" value=" Details">        <%! WHAT SHOULD I PUT HERE TO PASS PROPERTY 'id' into FORM BEAN 'position'? %>     </html:submit>     </td>           <td><bean:write name="element" property="id"/></td>           <td><bean:write name="element" property="name"/></td>         </tr>  </table> </logic:iterate>     I tried different things here but it does not work, or produce error.   Any hints how to do it, or is there better way to approach it?       Thanks in advance,       JK
