Help with form variables

[kiuma <ki...@usa.net>]

Hi all,
I'm trying to do the following thing:


<c:if test="${principalId != null}">       
  <td><bean-el:message key="label.login"/></td>
  <td>
    <c:out value="${principalId}"/>
    <html-el:hidden property="principalId"/>
  </td>
</c:if>
<c:if test="${principalId == null}">       
  <td><bean-el:message key="label.login"/></td>
  <td width='100%'>
    <html-el:text property="principalId" size="35" maxlength="255"/>
  </td>
</c:if>

the problem is that I want to take control over principalId form var, 
but mine seems not to be the right solution.
How can I make ?
Thx,
kiuma
