public class NullCapableFieldPrompt
extends Object

Class NullCapableFieldPrompt: Provide a widget which combines a Text entry field with a trailing button to toggle a null value state for the field, disabling (and blanking) the text part when null. For prompting for database fields with ALWNULL DDS keyword. It was simpler to setup this class for both standard fields and ALWNULL fields, from the point of view of the callers. Further decided to link in the the ISeriesDataTableColumnAdapter instance, to be able to directly link to it's data type validation from calls to here. Further decided to link in the Dialog instance calling this, so that the validity checks here and on column adapter can call the setErrorMesage() and setPageComplete() in the dialog. (And set up the common parent dialog class ISeriesDataTableViewPromptDialog for the 2 dialogs which use this class.)
