java - Spring SimpleFormController onSubmit request parameters -

-

I am using SimpleFormController in my application to handle form submisions. One thing that I am missing is the request object which has passed onSubmit (request, response ..) is different from the initial request object which is received by formBackingObject (..) Happens . Obviously because this is the new request from the web once again.

I want to use the same parameters from the requested object in submit (..) formBackingObject (..) .

It may be possible that I can collect them from the hidden areas by jossi, but I am trying to get some elegant perspectives.

Is there any way to do this?

Edit:

I'm overriding 

  formBackingObject (HTTPSArlet Request) `

and

<<>

Methods in my class.

> Formbacking object (..) will be called for intent view and I will have some variables from the request object if the user forms If I am called onsmember (..) , then I have another request that is different from the object which I received in formbackingObject (..) .

What I am asking, is there any way to catch the initial 'request' parameter (like request.getParameter () ), so that I can use them You can send onsite (..) to send them back & amp; Through hidden areas? '

formBackingObject () The method is being called when the user starts the initial form Requests for the scene. This is a completely different HTTP request when a user submits the form on which the onsmitt () method is called.

If you want to save the state with the first HTTP request, it is available in another HTTP request, your best option is to save it in an HTTP session.

Example: In your formBackingObject () method: 

  http session session = request.getSession (); Session.setAttribute ("param1", request.getParameter ("param1")); Session.setAttribute ("Ultimate 2", request.getParameter ("param2"));

and your onSubmit () method: 

  http session session = request.getSession (); String Param 1 = (string) session.getAttribute ("param1"); String param2 = (string) session.getAttribute ("param2");

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
