I have select box which reads the value from the property file. When there are validation errors, i am trying to regenerate the page, but i am getting this error.
BeanUtils.populate: java.lang.IllegalArgumentException: argument type mismatch

Why am I getting this, onload works fine, it brings the dropdown values from the property file, but when the form is being validated , it give me mismatch error.

The value of the dropdown is generated in
MainAction,Mainform and calls the InputAction and Inputform.
On error I am redirecting to Mainform,but gives error.
