    text
    copied!<p>I am using Spring 3.0.2, Hibernate 3,5 (not sure) and JSP to create a web application. While creating a simple form (backed by pojo with simple attributes), everything works just fine. However now I am trying to create form like this:<br/></p> <ul><li>backing pojo is Person with let's say String name attribute</li> <li>Person has Set contacts attribute</li> <li>Contact pojo has String city and String phoneNumber attributes</li> </ul> <p>I would like to be able to edit all the information on one page which means editing name, specifying city and phoneNumber.<br/> Can any one of you direct me to the right path on how to bind nested collections?<br/> Should I create ModelAttribute("contactsForPerson") in the controller and pass it to the jsp and use this in my jsp?</p> <pre><code>&lt;form:form method="post" modelAttribute="person" &gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt;&lt;form:hidden path="idPerson"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Name&lt;/td&gt; &lt;td&gt;&lt;form:input path="name" value="${person.name}"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;c:forEach items="${contactsForPerson}" var="a"&gt; &lt;tr&gt; &lt;td&gt;City&lt;/td&gt; &lt;td&gt;&lt;form:input path="contacts.city" value="${a.city}"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Phone Number&lt;/td&gt; &lt;td&gt;&lt;form:input path="contacts.phoneNumber" value="${a.phoneNumber}"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/c:forEach&gt; &lt;/table&gt; </code></pre> <p> Question itself boils down to how to specity path attribute of Person so that set of Contacts is binded :)</p> <p>Thanks in advance for your advice</p>
