Issue: I am performing integer validation for a field which is bound to a backing bean field of type "int". For this field I have given integer commons validator tag (<val:integer/>). When I enter a non-integer value for this field and submit the form, I get a "Conversion error occurred" error message in the page instead of the specific error thrown from commons validator. It is because the JSF performs the conversion before validation and hence the conversion error is thrown. Can anyone suggest a way(if any) to overcome this issue and throw the specific error of commons validator?
