Re: A table on a form from a List of Lists

the second iterate will treat row like a bean and will try to retrieve the value of property called list of fields and it will result in an erroe because the row is actually a List and not a bean and it does not have a property called listofFields. and i dont think html:text works without a property attribute

And by this way ?
<html:form action="/myAction">
<table>
<logic:iterate id="row" name="myForm" proprties="listOfRows">
   <tr>
   <logic:iterate id="myField" name="row" proprties="listOfFields">
       <td>
           <html:text name="myField"/>
       </td>
   </logic:iterate>
   </tr>
</logic:iterate>
</table>
</html:form>
but the problem is that you didn't know which row is the parent of a field

if this works, it will take care of writing the table to the jsp but i
need
an html input type of field so i can also set the properties of the ActionForm by editing the fields and submiting the form. ----- Original Message ----- From: "Cedric Levieux" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <user@struts.apache.org>; "Hubert Rabago" <[EMAIL PROTECTED]> Sent: Tuesday, January 25, 2005 3:36 PM Subject: Re: A table on a form from a List of Lists
