Specified by:

fetchYourValueFromRequest in class MustInputField

Parameters:

request - the current request

destroy

public void destroy()

Description copied from interface: Markupable

Destroys the markupable. Useful to release e.g. static references which prevent the garbage collector from finalizing. For example HalfDataComboBoxes add s as Listeners to database changes. These listeners are registered statically. Thus, these listeners cannot be removed by the garbage collector, they have to be removed manually. This may be done by calling this destroy method.

Specified by:

destroy in interface Markupable

Overrides:

destroy in class MustInputField
