Answer 1

As you mentioned, you need a user-friendly message in messages.properties. You can use one of the following message codes (with different levels of selectivity):

• typeMismatch.section.value
• typeMismatch.value
• typeMismatch.int
• typeMismatch

Also, when you don't know message code, you can simply print the BindingResult - its toString() returns the full description of the binding errors.
