Hello,
I'm using Struts 2.0.11.
I have an HTML table. Each row in the table represents a Person object.
Each column in the table has an input box for properties about the
person, such as firstName, lastName, etc.
My Action has a Persons property that is a List<Person>. Each input box
in the HTML table is indexed so as to populate the correct Person, for
example:
<input type="text" name="persons[0].firstName" value="Fred" />
When the user posts the form, Struts 2 will populate the Person objects
appropriately. So far so good. However, I want to apply validations to
the input. For example, firstName is required. I want to use
annotations for these validations as that is how I've done it elsewhere.
I added this annotation to the method in the Action:
@Validations(
requiredStrings={
@RequiredStringValidator( type=ValidatorType.SIMPLE, fieldName =
"persons.firstName", message = "person.firstname.required" )
}
)
Hoping that the firstName property of each Person within List<Person>
would be checked to see if a value is provided. However, it doesn't
seem to work; it always reports an error, even if all of the firstName
input boxes are filled in.
How can I validate the contents of objects within collections using
annotations?
Thank you!!!
