No method found when submitting form

[Lyc1]

Hello,

When I try to submit a form build with Springlayout, I have to following error :

net.sf.springlayout.web.controller.NoSuchControllerMethodException: No public method in controller with name 'No Method Specified' in class 'eu.b2i.telematic.rus.server.presentation.controller.TestController'
    at net.sf.springlayout.web.controller.AbstractBaseFormController.onSubmit(AbstractBaseFormController.java:282)
    at org.springframework.web.servlet.mvc.SimpleFormController.processFormSubmission(SimpleFormController.java:267)
    at net.sf.springlayout.web.controller.AbstractBaseFormController.processFormSubmission(AbstractBaseFormController.java:1038)

    at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:755)
...

It seems that the "method" parameter is not found. But if I check HTTP request sent to the server, I can see that :

...
Content-Type: multipart/form-data; boundary=---------------------------4122892432213
Content-Length: 1705
-----------------------------4122892432213
Content-Disposition: form-data; name="e"

1
...
-----------------------------4122892432213
Content-Disposition: form-data; name="method"

save
-----------------------------4122892432213--

I don't think that this notation can be considered as HTTP parameter declaration.

So what's wrong with my configuration ?

Thanks

Hi Damien,

When submitting a form using SpringLayout you need to have a parameter named 'method' in the parameter map. The value of this parameter is the name of the method in your controller which will be called. For instance if the value 'modify' is given, the method:

public ModelAndView modify(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception
   {
    ...
   }

needs to exist in your controller and will be called on post. SpringLayout provides a convenience javascript method:
performAction(formName, methodName); which will create the parameter 'method' and populate it with the value provided in methodName and post the form.

I found the problem.

I did a test thanks to theses examples :
http://springlayout.svn.sourceforge.net/viewvc/springlayout/trunk/src/main/webapp/test.jsp?revision=20&view=markup

The form is configured with enctype="multipart/form-data", which can't work in the controller (request.getParameter("method") doesn't work form multipart form)

I think something else must be configured in my bean to handle multipart form request. Anyway, it works as-is with classical form.

I think you might find that this isn't the problem. I have a number of controller examples where the form is using enctype="multipart/form-data" and they work correctly, the method parameter is recovered just fine.

Do you have a MultipartReslover configured?

[Lyc1]

Ok,I understand now.
MultipartResolver was a part of Spring that I didn't know.

It works as expected know.

That's for your help
