Jeet,

Try annotating your controller with @Controller

Hi ralscha,
first, I think you did a great job!

Now, I'd like to modify the HttpServletRequest for each of my remoted methods in a central location, eg. within an extended controller or with a handlerAdapter... whatever.
Is it possible to register an own Controller (which extends RouterController) or something like that?

Another question (maybe you know something about): Is it possible to work with generics/abstract classes using jackson?

Best regards,
Alina

Spring has this HandlerInterceptors. http://static.springsource.org/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-handlermapping-interceptor
I'm wondering if this helps with your problem. Don't know if and how this works because I have no experience with that.

I use generic collections with jackson (store methods). That works well. I have no experience with abstract classes.

Hi Ralph,
thanks for your immediate response!

Do you know a proper example how to configure Jackson properly? I do not really get the point how to do...
Besides, does Ext.Direct Spring provide *any* hook to add custom behaviour? Haven't seen any by now!

Thanks, Alina

You don't have to configure Jackson. Just add the jackson jars to the classpath and Spring will pick it up.

You can configure the ObjectMapper if you want. Create your own MappingJacksonHttpMessageConverter set the property objectMapper with the configured ObjectMapper. Here is the description how to configure the Converter

Hello,
we are migrating Ext JS 3 to Ext JS 4.
i am wondering does ExtDirectSpring support Ext JS 4?
i found that in google code the message:

Ext.Direct Spring is a library that implements the Ext.Direct specification with Spring 3 and Java. The library supports all the features of Ext.Direct

[ralscha]

Yes it's working with ExtJs4. There are a couple of demos on this page:
http://extdirectspring.ralscha.ch/demo/
Also named parameters (new feature in extjs4) is supported.

Thanks a lot~
now we can focus on other parts...

How can I send JSON data to extdirectspring? I want to manually create an additional parameter to hold grid values and add it to the submit. Currently, I am doing it like this:

var gridItems = myStore.getRange();
var myValues = [];
for (var i in gridItems) {
    myValues.push(gridItems[i].data);
    }
    myForm.getForm().submit({
    params : {
        action : "update",
        myList: Ext.JSON.encode(myValues)
    }
});

However, only the myList is json Encoded and is thus not understood by

@Transactional(propagation=Propagation.REQUIRED)
@ExtDirectMethod(ExtDirectMethodType.FORM_POST)
@ResponseBody
@RequestMapping(value = "/updateMyForm", method = RequestMethod.POST)
public ExtDirectResponse updateBasicInfo(Locale locale, HttpServletRequest request, MyValueObject vo, BindingResult result) {

    if (vo.getMyList() != null)
    {
        log.debug("Not null");
    }
    else {
        log.debug("Null");
    }

    ExtDirectResponseBuilder builder = new ExtDirectResponseBuilder(request);
    return builder.build();
}

in my Controller.

The problem is that the names of the parameters on the client side have to match the method parameter names on the server side. In your code there is no parameter with the name action or myList

@RequestMapping(value = "/updateMyForm", method = RequestMethod.POST)
public ExtDirectResponse updateBasicInfo(Locale locale, HttpServletRequest request, @RequestParam("action")String action, @RequestParam("
myList
") String 
myList
) {
....
}

This should work and myList should contain the json string.
The next thing you could try is not encoding the parameter on the client side:

 params : {
        action : "update",
        myList: myValues
    }

and then use a parameter like this:

@RequestParam("
myList
") List<String> myList

Not sure if that works.
