How to prevent of selecting another row in TableView in JavaFX

Suppose, I would like to implement data validation in JavaFX TableView.

Once user have changed data in the row, I would like to check it when user is trying to change current row number. Once data is correct, I would like to allow row change, once data is incorrect, I want to disallow this.

How to implement this?

Currently, I am trying to add a listener

getSelectionModel().selectedIndexProperty().addListener(indexFromTableToModel);

but any operations inside it causes bad table view behavior. Using

Platform.runLater

makes situation better, but still imperfect.

Is there a convenient place, to perform row data validation and perform different operation depending on it?

You can write your own selection model that can be locked (if current value is invalid). In that case the model won't change the internal selected index.
