<Error>: CGAffineTransformInvert: singular matrix in JFXSlider

[guoyiteng]

When I try to use JFXSlider in fxml, the console prints out this error. (macOS)

This error does not appear in Windows.

it's hard to tell whats causing the problem, if you provide more details about your code, the fxml controller, and java stacktrace we might be able to help.

Besides the error message, was there any issues using these controls?

Same issue here.
The slider works fine but having the error appear in the log every time I adjust the slider is annoying.

If I have just a simple slider like so, the error is still present

<?xml version="1.0" encoding="UTF-8"?>

<?import com.jfoenix.controls.JFXSlider?>
<?import javafx.scene.layout.AnchorPane?>


<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/9" xmlns:fx="http://javafx.com/fxml/1">
   <children>
      <JFXSlider layoutX="230.0" layoutY="184.0" />
   </children>
</AnchorPane>

I still get the error message

P.S. I'm a massive fan of JFoenix, thank you very much.

Hi,
I'm not sure what's causing this exception, can you provide more details about the environment you are using?

it seems that this issue is somehow related to Mac OS (still looking into it, not sure though)

Hi there, I have the same error upon moving the JFXSlider, with no stack trace.

Also, I'm using Scenebuilder and loading an fxml file, on which I get the error message twice for one slider. And yep, I get it on macOS 10.12.6 but not on Windows 7 SP1. No other effects though, it's working just fine - and another big thank you for JFoenix!

Any help in debugging this issue is appreciated, as I don't have MacOS :s so it's somehow impossible for me to track down.
