/**
|
|
* Represents a field in a form.
|
|
*
|
|
* A FieldList contains a number of FormField objects which make up the whole
|
|
* of a form. In addition to single fields, FormField objects can be
|
|
* "composite", for example, the {@link TabSet} field. Composite fields let us
|
|
* define complex forms without having to resort to custom HTML.
|
|
*
|
|
* <b>Subclassing</b>
|
|
*
|
|
* Define a {@link dataValue()} method that returns a value suitable for
|
|
* inserting into a single database field. For example, you might tidy up the
|
|
* format of a date or currency field. Define {@link saveInto()} to totally
|
|
* customise saving. For example, data might be saved to the filesystem instead
|
|
* of the data record, or saved to a component of the data record instead of
|
|
* the data record itself. Define {@link validate()} to validate the form field
|
|
* and ensure that the content provided is valid.
