este doplnim, tu je cely problem celkom pekne popisany:
http://opensource.atlassian.com/confluence/spring/display/DISC/java.lang.Integer+properties+of+Command+objects
kde je popisane aj nasledovne: "Spring provides a CustomerNumberEditor^
<http://www.springframework.org/docs/api/org/springframework/beans/propertyeditors/CustomNumberEditor.html>
for converting Strings to Numbers, such as java.lang.Integer. Note that
CustomNumberEditor will convert to all subclasses of java.lang.Number.
Spring does *not* wire this property editor automatically because it is
meant to be configured with a Locale. Each web request may provide a
different Locale (depending on the client), which forces the setup of
CustomNumberEditor to be performed at request time."

vygooglil som zatial toto:
I have some default binding error messages configured for scenarios
where a form values can't be bound. For example, when a string in the
form can't be bound to a Long value. A subset of my
messages.properties looks like:
typeMismatch.java.lang.Integer=Must specify an integer value.
typeMismatch.java.lang.Long=Must specify an integer value.
typeMismatch.java.lang.Float=Must specify a decimal value.
typeMismatch.java.lang.Double=Must specify a decimal value.
takze v resource bundle (messages.properties) staci prepisat tieto
hlasky ako potrebujem. vyskusal som a funguje.
property mam typu Integer.

Jen tak od boku; Tohle se mi stava pri validaci, kdyz property je typu
"int" nikoliv java.lang.Integer (nebo setAge(Integer age) vyhodi vyjimku
NullPointerException)
Failed to convert property value of type [java.lang.String] to
required type
[java.lang.Integer] for property age; nested exception is
java.lang.NumberFormatException: For input string: "aaa"
