title: problem between selected s tag default value and chosen value
body: <p>I have a OrganisationName select box in Edit/Add User Page.</p>
  
  <pre><code>&lt;s:select key="user.organisationname" name="entity.organisationId" list="organisationList" listKey="organisationId" listValue="organisationName"&gt;&lt;/s:select&gt;
  </code></pre>
  
  <p>I have two situations for Two Login User Type (System Admin &amp; Organisation Admin).</p>
  
  <p>1)Existing User, OrgnisationName will be displayed accordingly to his/her organisationId.</p>
  
  <p>2)For New User, Login user can select any desired OrganisationName from the select box.</p>
  
  <p><em><strong>for System Admin, select box will display all Organisation Name.
  but for Organisatoin Admin, select box will display only his related Organisation Name.</em></strong> </p>
  
  <p>My problem is I use if else to check whether the login user is System Admin or Org Admin.And I disabled the select box if the login user is Org Admin.</p>
  
  <p>The problem starts from this point. When I disabled the select box, I can see the correct OrganisationName. but <strong>When I save the edited user, the organisationId returned from select box always become 0.</strong> </p>
  
  <p><em><strong>How can I pass the correct value even I disable the select box?</em></strong></p>
  
  <p>Another Question: <strong>Is there any way that to visible = "false" , similar property for select tag?</strong></p>
  
  <p>Thanks.</p>
