Hi,

The following snippet is repeated 5 times on a JSP page. The object “aliases” is obviously an Iterator and if there is a “next” value it becomes the VALUE argument in the INPUT element. The designer flags errors but the page displays correctly, including displaying the value argument when applicable. Can anyone tell me why the designer is complaining?


<td>
<input type="text" name="alt.01" id="alt.01" size="24"
  maxlength="24" style="font-family:monospace; color:#7f0000"
    <% 
        if ( aliases.hasNext()  ) 
                 out.println(" value=\"" + aliases.next() + "\"");
    %> />
</td>

Thanks,
Rob

What error do you see?

I created a page like this:


<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
    String path = request.getContextPath();
    String basePath = request.getScheme() + "://"
            + request.getServerName() + ":" + request.getServerPort()
            + path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
    <head>
        <base href="<%=basePath%>">

   %> />
                </td>
            </tr>
        </table>
        This is my JSP page.
        <br>
    </body>
</html>

And there is no errors or warnings.

This is the error — actually it’s a yellow warning:


Undefined attribute name (<% 
                    if 
                             ( aliases.hasNext()  )
                                                
                             out.println(" value=\"" + aliases.next() + "\"");
                                        
                                        %>).

Hi Rob,
Even I was unable to reproduce this warning at my end. Can you paste the JSP Code that is giving you the warning. What version of MyEclipse are you using ?
