Why can't i select JFXTextfield in scenebuilder and add it

Question

JFTTextArea and JFXButton works but why not the JFXTextField?

I have added foenix Library so I have got all the JFXTextField But i am not able to place JFXTextField in the SceneBuilder !!

Here I have added the library in the project structure.

If i forcefully add JFXTextField in the sample.xml in the text mode, It doesn't show compiler error But instead shows

Unable to make boolean java.lang.reflect.AccessibleObject.setAccessible0(boolean) accessible: module java.base does not "opens java.lang.reflect" to module com.jfoenix

The complete Error looks like:

I even Tried with this link Stack OverFlow: Reflection error But couldn't very well connect :(

My sample.xml goes like so:

<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/11.0.2" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sample.Controller">

Answer 1

I have the latest version of java and I am using the latest version of JFoenix and I am getting the same InaccessibleObjectException as you. There seems to be a problem on their side, I have just contacted them and we will have to wait until they fix it. Link to the issue: Not able to add JFXTextField in Scene Builder 16.0.0 #1205

Answer 2

Please use jfoenix 9.0.1 and not 9.0.10 from marven for any jdk/scenebuilder version. It worked for me

Answer 3

I had the same problem while using SceneBuilder 16.0 and JFoenix 9.0.10. The solution I tried is using an earlier version of SceneBuilder, I downloaded SceneBuilder 11.0 and it worked.

This bug has not been corrected by JFoenix yet.

Answer 4

downloaded SceneBuilder 15.0.0 and use JFoenix 9.0.10 and use java-sdk-15.0.1 and java jdk 15.0.0 or jdk 15.0.1 and add the following settings in your arguments VM :

--add-exports javafx.graphics/com.sun.javafx.scene=com.jfoenix --add-exports javafx.controls/com.sun.javafx.scene.control.behavior=com.jfoenix --add-exports javafx.controls/com.sun.javafx.scene.control=com.jfoenix --add-exports javafx.base/com.sun.javafx.binding=com.jfoenix --add-exports javafx.base/com.sun.javafx.event=com.jfoenix --add-exports javafx.graphics/com.sun.javafx.stage=com.jfoenix --add-opens=java.base/java.lang.reflect=com.jfoenix
