Asif this is the correct behavior. When the request doesn't contain a request parameter, then the value of a parameter is null. If the request parameter exists, and has no value, then it is equivalent to an empty string. I think to avoid this, you must use the requiredstring-validator or implement your own parameter interceptor but the former would be the correct way of doing this...
