Duplicating a table column crashes SceneBuilder

[ghost]

To replicate: create a new scene, add an anchor pane, add a tableview, right-click the column in the tableview, select duplicate, then crash.

Note: This only seems to crash SceneBuilder when launched from IntelliJ IDEA (Ultimate in my case, Community untested). However, it seems that an NPE might be thrown regardless of how SceneBuilder was launched, but that it does not cause a crash when launched independently from IntelliJ.

To encircle the possible error I attempted to reproduce the error. As of now, I was not able to successfully reproduce the issue. Could you pleas provide more boundary conditiosn?

Which Java version? Which SceneBuilder version? Was it the SceneBuilder provided by IDEA or was the SceneBuilder separately provided and configured in Idea accordingly? Is it possible to reproduce using a provided FXML file?

Tested with:

Version	OS	Package	Java Runtime	Observation
8.5	Windows 10	Standalone	1.8.0_171-b11, Oracle Corporation	works, no crash
15.0.1	Windows 10	MSI Installer	15.0.2+7, AdoptOpenJDK	works, no crash
11	Windows 10	IntelliJ 2020.1 Ultimate, 201.6668.121	11.0.6+8-b765.25 amd64, JetBrains	works, no crash

Hi,

I managed to reproduce it by launching scene builder from IntelliJ coummunity edition 2020.2

Is the issue solved? This problem is reproduced here. BTW, I am using NetBeans and still this occured.

[Oliver-Loeffler]

Well, If it reproduces in Linux, I will also try again and also try to catch the thing with the debugger.

Reproduced on Windows 10 with latest SB build:

java.lang.NullPointerException: Cannot invoke "javafx.scene.control.TableView.getSkin()" because the return value of "javafx.scene.control.TableColumn.getTableView()" is null
	at javafx.scene.control.TableColumn.getStyleableNode(TableColumn.java:646)

	at com.oracle.javafx.scenebuilder.kit.editor.panel.util.AbstractPanelController.lambda$new$5(AbstractPanelController.java:232)

Looks like when the column is duplicated, the table view is not added to it.

I cannot duplicate this using Scene Builder 19 on macOS 12.0.1.
