Runtime expression not evaluated

[dh...@lexmark.com]

Hi,

Can anyone tell me why, in the following code, the id of the image is
"checkBox<%=index%>" rather than "checkBox1", "checkBox2" etc.?  The id of the
<td> works just fine!

                        <logic:iterate id="comboValue" name="Prompt"
property="comboValues" indexId="index">
                        <TR>
                           <td ID="multiValue<%=index%>"><bean:write
name="comboValue"/></td>
                           <TD>
                              <A href="javascript:onMultiPress(<%= index %>)"
style="cursor:default">
                                 <html:img styleId="checkBox<%=index%>"
page="/images/checkbox_empty.gif" border="0"/>
                              </A>
                           </TD>
                         </TR>
                        </logic:iterate>

Thanks,

David

You can't mix a string and a <%= %> in an attribute value. It has to be one
or the other. I know, it seems weird, but try it and you'll see.

You should be able to do one of these instead:

<% String idValue = "multiValue" + String.valueOf(index); %>
<td ID="<%=idValue%>">

or

<td ID='<%=("multiValue" + String.valueOf(index))%>'>

^ note single quote usage
