Everything started when I updated my JavaFX version:

When I click on "Make Controller" option in my FXML file, there are some kind of "extra updates", which cause that after 2 times I click on this option I get something like:

<AnchorPane fx:id="anchorWarrning" prefHeight="356.0" prefWidth="600.0"
xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2"
fx:controller="GUI.Addons.Alerts.WarrningGUIController"
fx:controller="GUI.Addons.Alerts.WarrningGUIController"> <---- 2 TIMES! :(
<children>

Additionally there is no .bak file which was automatically created next to my FXML file when was modyfing it in Scene Builder.

Could someone could tell me what is happening?
