问题 Is there any simple approach to let the TreeTableView (or TableView) try to commit values on focus lost? Unfortunatly I didn't succed with any default-implementations of javafx TableCellFactories, which is why I tried my own TreeTableCell implementations and also some different tableCell implementations like the one from Graham Smith, which seemed the most straight forward, since it already implemented a hook for focus lost, but nevertheless the value is never committed and the userchanges
