Ability to clear "modified" state of a detail view

[knstvk]

On the detail view screen, there is an action that calls a Spring component where the entity is passed and modified. The data context listeners are triggered, and its state is changed to modified. Accordingly, if the user tries to close the screen, a dialog box saying "there are unsaved changes" will appear. If dataContext.evictModified() is called, it is expected that the dialog box will not appear anymore and the screen will close. However, there is a flag StandardDetailView#modifiedAfterOpen on the screen that is changed precisely because the listener in the data context was triggered, and it is not possible to change this flag.
