validation: how to make int and double validations work ?

[Boris Romashov]

Say I want to validate field number.

This is a snippet from MyAction-validation.xml

    <field name="number">
        <field-validator type="int">
            <message>qwe</message>
        </field-validator>
    </field>

There are 2 cases.
1) If number is field of class String then this validation doesn't work at all
2) If number is field of type int then this validation doesn't work also, but besides if I enter not a number then the following exception is thrown:

java.lang.NoSuchMethodException: setNumber([Ljava.lang.String;)

and instead of my text I see at the page:

Invalid field value for field "number"

So, in both cases int validation doesn't work. The same for double validator.
What to do ?

If the action property is a string then no, validating it as an integer won't work: strings and ints aren't the same things.

If the action property is an int then as far as I know the int validator works, I've been using it successfully for almost every S2 version. If you enter something that isn't a number then you're getting a type conversion exception. Type conversion messages are added to the field's errors via the "conversion" interceptor.

How can I handle this errors?
