+ <h3>Responsibilities</h3>
<p>A <type>FormController</type> is responsible for a <type scope="com::sun::star::awt">UnoControlContainer</type>,
and all controls therein.</p>
+ <p>Furthermore, a form controller is responsible for preventing invalid user input. That is, if the form
+ contains controls bound to a database, or to an external validator, then the form controller will
+ check their current value when the current record is to be saved to the database.</p>
+ <p>First, it will check whether any controls with an external validator exist. If so, those validators
+ will be asked to validate the current control content. If this fails, the message provided by the validator
+ is displayed to the user, the control is focused, and the update of the record is vetoed.</p>
+ <p>Second, the controls are examined for NULL values. If a control is bound to a database field which
+ is declared to be <code>NOT NULL</code>, no auto-increment field, but still <NULL/>, then an error
+ message is shown to the user saying that input is required, the respective control is focused, and
+ the update of the record is vetoed.</p>
+ <p>Note that you can precent the second check - for database fields containing <NULL/> values - on
+ a per-form and a per-database basis.<br/>
+ For the former, you need to add a boolean property <code>FormsCheckRequiredFields</code> to the form
+ (aka the <code>FormController</code>'s model), using its
+ <member scope="com::sun::star::beans">XPropertyContainer::addProperty</member> method, with a value
+ of <FALSE/>.<br/>
+ For the latter, you need to set the respective property of the data source's <code>Settings</code>
+ (also named <code>FormsCheckRequiredFields</code>) to <FALSE/>.</p>
