Spring tiles2 form submit

[Bjorn121]

I've been struggling with this for a very long time, so I hope that someone here can help me.

I have a simple test application, which contains a form to add delivery addresses. It's possible with Javascript to add rows to the table and bind them to a User object. I've only added a field to add a street and the number (String and Integer).

The problem is, everything works fine when I don't use Tiles. I can add rows to the table, bind them to the objects and submit the form. When I add Tiles to the application, nothing works anymore.

Some excerpts of the code:

    <bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
        <property name="definitions">
            <list>
                <value>/WEB-INF/tiles-def.xml</value>
            </list>
        </property>
    </bean>

    <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="order" value="1" />
        <property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView" />
    </bean>
    
    <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <value>
                /welcome.html = welcomeController
                /changeaddress.html = changeAddressController
                /changeaddress.form = changeAddressFormController
            </value>
        </property>
    </bean>

    <bean id="welcomeController" class="org..controller.WelcomeController" />

    <bean id="changeAddressController" class="org.test.controller.ChangeAddressController" />

    <bean id="changeAddressFormController" class="org.test.controller.ChangeAddressFormController" />

Tiles-definition:

    <definition name="template" template="/WEB-INF/jsp/template.jsp" />

    <definition name="welcome" extends="template">
        <put-attribute name="content" value="/WEB-INF/jsp/welcome.jsp" />
    </definition>

    <definition name="changeaddress" extends="template">
        <put-attribute name="content" value="/WEB-INF/jsp/changeaddress.jsp" />
    </definition>

    <definition name="addresschanged" extends="template">
        <put-attribute name="content" value="/WEB-INF/jsp/addresschanged.jsp" />
    </definition>

JSP:

        <h4>Change addresses</h4>

        <form method="post" action="${pageContext.request.contextPath}/changeaddress.form">
            <table>
                <tbody id="addressTable">
                    <tr>
                        <td>First name:</td>
                        <td><s:bind path="user.firstName"><input type="text" size="20" name="firstName" value="${status.value}" /> ${status.errorMessage}</s:bind></td>
                    </tr>
                    <tr>
                        <td>Last name:</td>
                        <td><s:bind path="user.lastName"><input type="text" size="20" name="lastName" value="${status.value}" /> ${status.errorMessage}</s:bind></td>
                    </tr>
                    <c:forEach items="${user.deliveryAddress}" var="deliveryAddress" varStatus="state">
                        <tr>
                            <td>Address ${state.index + 1}</td>
                        </tr>
                        <tr>
                            <td>Street:</td>
                            <td><s:bind path="user.deliveryAddress[${deliveryAddress.key}].street"><input type="text" size="20" name="${status.expression}" value="${status.value}"/></s:bind></td>
                        </tr>
                        <tr>
                            <td>Number:</td>
                            <td><s:bind path="user.deliveryAddress[${deliveryAddress.key}].number"><input type="text" size="3" name="${status.expression}" value="${status.value}" /></s:bind></td>
                        </tr>
                    </c:forEach>
                </tbody>
            </table>
            <button onclick="addRow();">Add row</button>&nbsp;<input type="submit" value="Submit" />

            <script type="text/javascript">var counter = ${state.index + 1}</script>
        </form>

Controller:

public class ChangeAddressFormController extends SimpleFormController
{
    @Override
    public ModelAndView onSubmit(Object command)
    {
        User user = (User) command;

         for(Integer i : user.getDeliveryAddress().keySet())
        {
            Address u = user.getDeliveryAddress().get(i);

            System.out.println("Street: " + u.getStreet());
            System.out.println("Number: " + u.getNumber());
            System.out.println("******************************");
        }
       return new ModelAndView("addresschanged");
    }

    protected Object formBackingObject(HttpServletRequest request) throws ServletException
    {
        return new User();    
    }
}

When I submit the form, I get the following stacktrace:

org.apache.tiles.impl.CannotRenderException: JSPException including path '/WEB-INF/jsp/changeaddress.jsp'.

Remove the spring tags & use ajax jquery for form submitting
