cg-rollback

Arguments: &key (confirm t) window

This function is called by the :rollback-button widget of an object-editor dialog (see command-buttons), and may also be called directly by application code.

It calls db.ac:rollback if the user confirms in a modal dialog, and displays a couple of status-bar messages in the specified window if one is passed. The confirmation dialog is skipped if the confirm argument is passed as nil.

It then ensures that any object-editor dialogs and class-grid widgets in the environment are brought up to date, by calling uncache-instances-with-pretty-names with the :all argument, and then calling update-all-class-interface-widgets. It is strongly recommended that any application that uses object-editors and/or class-grids call this function rather than calling db.ac:commit directly, or else to call those two exported functions that cg-rollback calls. Otherwise the interface objects may be left in a broken state.
