The component produced by CheckBoxTableCell.forTableColumn(c) nicely renders checkmarks whenever c is bound to BooleanProperty having a value of "true". But when c is bound to ObjectProperty<Boolean> having a value of "true" it renders a blank check box. This is not very smart. The component should be clever enough to treat ObjectPropert<Boolean> simply as BooleanProperty, with a simple difference: When the value "null" there should be no (not even blank) check box getting rendered at all.
