    <p>I have a list containing users. I am trying to print it in JSP but some how I am not able to get it to print it. Getting this exception <code>HTTP Status 500 - javax.servlet.ServletException: javax.servlet.jsp.JspTagException: Neither BindingResult nor plain target object for bean name 'users[0]' available as request attribute</code></p> <p>Code in JSP</p> <pre><code>&lt;c:forEach items="${users}" var="user" varStatus="status"&gt; &lt;spring:bind path="users[${status.index}].name"&gt; &lt;c:out value="${status.value}" /&gt; &lt;/spring:bind&gt; &lt;/c:forEach&gt; </code></pre> <p>Controller</p> <pre><code>ModelAndView modelAndView = new ModelAndView("go_some_JSP_page"); List&lt;UserEntity&gt; users = userManager.getAllObjects(); modelAndView.addObject("users", users); </code></pre> <p>BTW, UserEntity has name field. If I remove the binding and try to print the <code>user.name</code> using <code>&lt;c:out value="user.name" /&gt;</code> it prints the value</p> <p>Where am I going wrong and what do I need to do? Thanks</p> <p>Not working code below. [I have to invoke formatting on field @NumberFormat so have to try it using <code>status</code> variable]</p> <pre><code>&lt;spring:bind path="user.name"&gt; &lt;c:out value="${status.value}" /&gt; &lt;/spring:bind&gt; </code></pre> <p>Gets this error --> <code>javax.servlet.ServletException: javax.servlet.jsp.JspTagException: Neither BindingResult nor plain target object for bean name 'user' available as request attribute</code></p> <p>So added a bean binding and then I get empty table :(. I believe thats because the instance is empty. So this does not seems like a right approach.</p> <pre><code>@ModelAttribute("user") public UserEntity userEntityBinding() { return UserEntity.newInstance(); } </code></pre> <p>A working code exists at <a href="https://github.com/hth/StatusInvoke.git" rel="nofollow">https://github.com/hth/StatusInvoke.git</a></p> <p>Let me know if you face any problem deploying it. </p> <p>This question has been solved. Thanks for looking at it.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
