IllegalArgumentException by Spring controller

I have a view(jsp) which use jquery to show/hide some field. I am using jquery to post data using ajax to the controller(spring mvc). Works good when I simply entered values in the page but if I click on a link to unhide 2 text boxes, input value into them and then send to the controller I got this exception. I have checked spring logs and I can see all properties were converted to bind with spring but soon after that exception was raised. Below is what I can see in the logs. I have checked all parameters multiple times and nothing is missing/misspelled in jsp/js/java. Any help would be much appreciated

A complete stack trace will be much appreciated. The problem could be, spring could not convert one of your method parameter. You should refactor that method, it has too many parameters. You could create a dto that wraps all of the parameters(except for those provided by Spring).

EDIT:

Instead of using a lot of @RequestParam annotations. You could wrap all your method parameters in one wrapper object (DTO).

Example: 

public class MyWrapperDTO {
    private String someStrValue;
    private String anotherStrValue;
    private int someIntValue;

    // getters/setters omitted
}

From here you could choose 2 options: using @ModelAttribute or @RequestBody

For the first one: 

@Controller
public class Controller {
    @RequestMapping(value = "/mypage/view")
    public ModelAndView viewPage() {
        MyWrapperDTO dto = new MyWrapperDTO();
        // you could provide default values for your form here
        return new ModelAndView("/mypage").
            .addObject("form", dto);
    }

    @RequestMapping(value = "/mypage/save", method = RequestMethod.POST)
    @ResponseBody
    public void doSomething(@ModelAttribute("form") MyWrapperDTO dto) {
        // process your ajax call here
        // do something
    }
}

Your jsp should look like this:

<spring:url var="myAjaxCall" value="/mypage/save" />

<!-- you should use spring form tag -->
<form:form commandName="form" action="${myAjaxCall}">
   <form:input path="someStrValue"></form:input>
   <form:input path="anotherStrValue"></form:input>
   <form:input path="someIntValue"></form:input>
   <input type="submit" value="Submit"></input>
</form:form>

Second option (@RequestBody), assuming you are sending a JSON object (this involves some jquery): 

@Controller
public class Controller {
    @RequestMapping(value = "/mypage/view")
    public ModelAndView viewPage() {
        MyWrapperDTO dto = new MyWrapperDTO();
        // you could provide default values for your form here
        return new ModelAndView("/mypage").
            .addObject("form", dto);
    }

    @RequestMapping(value = "/mypage/save", method = RequestMethod.POST)
    @ResponseBody
    public void doSomething(@RequestBody MyWrapperDTO dto) {
        // process your ajax call here
        // do something
    }
}

for your jsp: 

<spring:url var="myAjaxCall" value="/mypage/save" />

<script type="text/javascript">
   $(document).ready(function() {
      $(document).on('click', '#submit', function() {
          // not the best way to do it
          var data = {
            'someStrValue': $('#someStrValue').val(),
            'anotherStrValue': $('#anotherStrValue').val(),
            'someIntValue': $('#someIntValue').val()
          };

          // use jQuery.ajax
          jQuery.ajax({
              'data': JSON.stringify(data),
              'type': 'POST',
              'ur': '${myAjaxCall}',
              'success': function(data) {
                   // yehey!
               }
          });
      });
    });
</script>

<!-- you should use spring form tag -->
<form:form commandName="form">
   <form:input id="someStrValue" path="someStrValue"></form:input>
   <form:input id="anotherStrValue" path="anotherStrValue"></form:input>
   <form:input id="someIntValue" path="someIntValue"></form:input>
   <button id="submit" type="button">Submit</button>
</form:form>

Spring will handle conversion/binding to your wrapper object. The second option requires you to have jackson in your classpath.
