*
* Added two new attributes: hidden and overrideValue
*
* hidden : Determines if the text field should be hidden or
displayed.
* overrideValue : Defines the text field's default value. When this
attribute is set, the value retrieved
* from the database is ignored.
*
* These attributes where added to allow a developer to:
* - set a field's default value (Insert mode)
* - override a field's value with a developer defined value (Update mode)
* - hide a field, set its value (Insert and Update mode)
*
* Example:
*
* From within a given JSP page, a developer is required to set the SOLD
field to 'true' when the user clicks
* the updateButton. The SOLD field should not to be displayed on screen.
*
* <db:textField fieldName="SOLD" hidden="true" overrideValue="true"/>
* <db:updateButton caption="OK"/>
