Class FieldRef

java.lang.Object
fc.web.forms.FieldRef
public final class FieldRef extends Object
Keeps track of a set of related/grouped fields in a form.

A fieldref is is useful when a set of fields are created programmatically from a database table and need to be retrieved from the form (but we don't know the names of those fields since they were created dynamically -- however, those fields can be added both to the form and to a fieldref and obtained via then the name of the fieldref (whose name we do know.)

Note: Any fields contained in this object must also be added directly to the form.
