* 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.
