    copied!<p>I have a form which contains some datafields and I have to pass some corresponding objects to be updated all together in a Spring controller. I'm not achieving to do it due to Spring thrown errors in matter of "Field error in object [parentObject] on field [nestedObject]".</p> <p>For what I imagine that I'm not dealing with these objects correctly. How can I manipulate this objects in order to Spring MVC recognize and manage it properly?</p> <p>Here goes the codes:</p> <p>Corresponding piece of JSP page:</p> <pre><code> &lt;form id="fmActivity" method="post" accept-charset="iso-8859-1,utf-8" novalidate&gt; &lt;div class="fitem"&gt; &lt;label&gt;Description&lt;/label&gt; &lt;textarea id="description" name="description" class="easyui-validatebox" required cols="40" rows="5"&gt; &lt;/textarea&gt; &lt;/div&gt; &lt;div class="fitem"&gt; &lt;label&gt;Comments&lt;/label&gt; &lt;textarea id="comments" name="comments" class="easyui-validatebox" cols="40" rows="5"&gt; &lt;/textarea&gt; &lt;/div&gt; &lt;!-- HERE ARE THE PROBLEMS: PROJECT, EXECUTOR AND DATETIME FIELDS ARE NOT PROCESSED BY SPRING &lt;div class="fitem"&gt; &lt;label&gt;Project (it would be hidden)&lt;/label&gt; &lt;input id="project" type="hidden" name="project" class="easyui-validatebox" required value="${project}"&gt; &lt;/div&gt; &lt;div class="fitem"&gt; &lt;label&gt;Executor (it would be hidden)&lt;/label&gt; &lt;input id="executor" type="hidden" name="executor" class="easyui-validatebox" required value="${executor}"&gt; &lt;/div&gt; &lt;div class="fitem"&gt; &lt;label&gt;Date/Time&lt;/label&gt; &lt;input id="dateTime" class="easyui-datetimebox" required name="dateTime" style="width:150px"&gt; &lt;/div&gt; --&gt; &lt;div class="fitem"&gt; &lt;label&gt;Tag&lt;/label&gt; &lt;input name="tag" class="easyui-validatebox" required&gt; &lt;/div&gt; &lt;input id="button1" name="button1" type="submit" value="submit"&gt; &lt;/form&gt; </code></pre> <p>The JQuery code to process the button click:</p> <pre><code>$('input#button1').click( function() { $.ajax({ url: 'ActivityUpdate', type: 'post', dataType: 'json', data: $('form#fmActivity').serialize(), success: function(data) { alert(data); }, error: function(errobj, str, errt){ alert(str + " " + errt); } }); }); </code></pre> <p>And the MVC Controller:</p> <pre><code>@RequestMapping(value = "/ActivityUpdate") public String update(Activity activity, HttpSession httpSession) { Session sess = (Session) httpSession.getAttribute("hibSess"); ActivityDAO actDao = new ActivityDAO(sess); actDao.persist(activity); return "forward:ActivityList"; } </code></pre> <p>When I try to do the processing without the objects PROJECT, EXECUTOR and the DateTime, it works. Can you help me? Thanks!</p>
