المحلول

This solved my problem...

<s:if test="hasActionErrors()">
  <div class="errors">
   <s:actionerror theme="jquery"/>
   </div>
 </s:if>

نصائح أخرى

jqGrid submit the delete row action by ajax, while those hasActionErrors are not ajax operations so they cannot be caught. In order to catch these action error/messages, that should not be a ajax/json action.
