Java Spring Controller mapped properly, but server returns 302 instead of 200

Question

I have following controller

@Controller
@RequestMapping("/adwords")
public class AdwordsController
{
    @RequestMapping(method = RequestMethod.GET)
    public ModelAndView showForm(@ModelAttribute(Const.ADWORDS_COMMAND) AdwordsCommand adwordsCommand, BindingResult result)
        throws HttpSessionRequiredException
    {
        this.checkSessionExpired();

        ModelAndView mav = new ModelAndView("adwords/adwordsRequest");

        if(adwordsCommand == null)
            adwordsCommand = new AdwordsCommand();
        User user = this.getUser();
        adwordsCommand.setEmail(user.getEmail());
        mav.addObject(Const.ADWORDS_COMMAND, adwordsCommand);

        return mav;
    }
}

That is mapped properly:

13:17:49,276  INFO RequestMappingHandlerMapping:185 - Mapped "{[/adwords],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public org.springframework.web.servlet.ModelAndView pl.ifirma.domeny.controller.adwords.AdwordsController.showForm(java.lang.String,org.springframework.validation.BindingResult) throws org.springframework.web.HttpSessionRequiredException

But when I type URL in browser I get 302 code and server redirects immediately to main page of application. Can anyone help? Why server does not return 200 or at least 404?

@Comments: Such code acts exactly the same.

@Controller
@RequestMapping("/adwords")
public class AdwordsController
{
    @RequestMapping(method = RequestMethod.GET)
    public ModelAndView showForm(@ModelAttribute(Const.ADWORDS_COMMAND) AdwordsCommand adwordsCommand, BindingResult result)
    {

        ModelAndView mav = new ModelAndView("adwords/adwordsRequest");

        if(adwordsCommand == null)
            adwordsCommand = new AdwordsCommand();
        User user = this.getUser();
        adwordsCommand.setEmail(user.getEmail());
        mav.addObject(Const.ADWORDS_COMMAND, adwordsCommand);

        return mav;
    }
}

I wonder if this weird redirection could be caused by some spring configuration, but where to check it? And it is only place in project where problem occurs.

Solved. There was a hidden redirect in a view...
