Got the solution!
For all other ComboBoxes, the declaration involved the respective value object.
For example:
@FXML // fx:id="projectComboBox"
private ComboBox<ProjectVO> projectComboBox; // Value injected by FXMLLoader
But, nameComboBox
was simple declared as:
@FXML // fx:id="nameComboBox"
private ComboBox<?> nameComboBox; // Value injected by FXMLLoader
Added NameVO
at the place of ?
and got rid of the problem.
