从Vaadin TextField中取消编辑/移除焦点

Question

Does anyone know how to cancel the editing state of a Vaadin TextField that's inside a Table? My concrete use case is that I have a table with multiple TextFields in it, that show different values when they are edited as opposed to viewed. The user clicks on a TextField, this makes the field display its editable content. If the user changes his mind and wants to stop editing the field (by pressing ESC) the field should cancel any changes the user might have made to its content and revert to displaying its view value.

So far I've been able to move the focus to another TextField but this is not what I ultimately want to achieve. Moving the focus to the parent Table would be acceptable, but doing so programmatically by calling table.focus() does not produce any visible results.

Thanks for your help,
