A Long Range validator is used to validate that the value
of a component does not exceed the standard range of the Java
long
data type. This data type is a signed integer
that ranges from -263 to 263-1, or
-9223372036854775808 to 9223372036854775807. Typically, the
way you add a validator to a JavaServer Faces component is to
edit the component's validator property, which provides a drop down list from
which you can select a validator.
