title: why updated values are not getting post in jqgrid
body: <p>I am implementing jqgrid using struts2-jqgrid-plugin. My problem is when I change a value of hidden field in form-element ,the updated values are not reflected when i post these hidden field with my jqgrid.</p>
  
  <p><strong>My form with jqgrid</strong></p>
  
  <pre><code>&lt;form name="adminFrm" id="adminFrm"&gt;
  &lt;div&gt;
  &lt;s:url var="remoteurl" action="adminJsontable"&gt;
      &lt;/s:url&gt;
      &lt;sjg:grid
          id="gridtable"
          caption="Issue-Summary"
          dataType="json"
          href="%{remoteurl}"
          pager="true"
          gridModel="finalGridModel"
          rowList="10,20,25,30"
          rowNum="10"
          rownumbers="true"
          width="1250"
          loadingText="Dashboard is being Loaded..."
          formIds="adminFrm" // here I am sending all form-elements
          gridview="true"   
       &gt;
          &lt;sjg:gridColumn  name="issue_id"  id="issueId"   index="id" title="Issue-ID" formatter="integer" formatoptions="{thousandsSeparator: ''}"  sortable="false" width="100"/&gt;
          &lt;sjg:gridColumn name="issue_status"  index="issue_status" title="Current Status" search="true" searchoptions="{value:':Any;Completed:Completed;Assigned:Assigned;Denied:Denied'}"             searchtype="select"/&gt;
  
      &lt;/sjg:grid&gt;
  
  &lt;/div&gt;
  &lt;s:hidden name="hidden_field" id="hidden_field" value="123456"&gt;&lt;/s:hidden&gt;   
    &lt;/form&gt;
  </code></pre>
  
  <p><strong>Here i am trying to update the hidden field value on some event</strong></p>
  
  <pre><code>function x()
  {
  $("#hidden_field").val("Value changed");
  }
  </code></pre>
  
  <p>But when <strong>jqgrid</strong> reloads, it still posting the previous value of hidden field i.e. 12345 instead updated value. I checked the hidden field using firebug ,that is also showing that the value of hidden field has been changed then why jqgrid is still posting the previous value to server(which i checked via firebug) which does not exist on page. how to solve this problem. for details you can refer this post <a href="https://stackoverflow.com/questions/15132873/issue-with-ajax-call-on-paging-in-jqgrid">issue with ajax call on paging in jqgrid</a></p>
