[tlg]

application can access formBackingObject of SimpleFormController , but it cann't call onSubmit, and directness call "successView":

<bean id="nationValidator" class="system.nationValidator"/>
<bean id="nationaddFormControllerid" class="system.nationFormController">
<property name="sessionForm"><value>true</value></property>
<property name="commandName"><value>nationbean</value></property>

<property name="formView"><value>system/test/nationInsert</value></property>
<property name="successView"><value>system/nationdo2</value></property> <property name="nationbeanManager">
<ref bean="nationbeanserverid"/>
</property>

I have find the error: it cann't use "public ModelAndView onSubmit(HttpServletRequest request,HttpServletResponse response,Object command,BindException ex) throws ServletException { " ,
must use "public ModelAndView onSubmit(Object command)
throws ServletException { "

if i have some other parameter .e.g <input type="hidden">, How to get it.

use:

protected void onBind(HttpServletRequest request, Object command) throws Exception {
tjj1 = request.getParameter("tjj1");
}

or

protected void initBinder(HttpServletRequest request,ServletRequestDataBinder binder) throws Exception {
tjj = request.getParameter("tjj");
}

up method is in reason?? if have any other way to get these values ??
