thanks for helping me! i have been solved it.. your idea was very good! before i use <%=(String)an_author%>, it throws a exception, '[ServletException in:/tiles/admin/selectAuthor.jsp] null'
i don't know why, because the author_id data type is a java.lang.Integer... until i changed it to <%=an_author.toString()%> , now ,it's work... ----- Original Message ----- From: "Claire Wall" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Saturday, November 29, 2003 12:56 AM Subject: Re: validation : the select field and checkbox field origin value lost... > Ricky, > > it is possible to do what you wish to do by doing the following (example > taken from a similiar thing that i did): > > <logic:iterate id="user" name="myForm" property="users"> > <bean:define id="id" property="id" name="user"/> > <html:option value="<%= (String)id %>"><bean:write name="user" > property="username"/></html:option> > </logic:iterate> > > here i am iterating through a list of User objects in my form (my User > object is basically a class with the fields 'id' and 'username').
