When using ValidField with a numeric validator, you must
set the type parameter of the ValidField to indicate the
Java type to convert to and from.
Example:
<component id="inputDouble" type="ValidField">
<binding name="validator"
expression="beans.doubleValidator"/>
<binding name="value"
expression="visit.doubleValue"/>
<static-binding name="displayName">Double
Field</static-binding>
<static-binding name="type">Double</static-binding>
</component>
