After deleting a data series, the UI deletion cannot be called.

[16637142795]

Children: duplicate children added: parent = ListViewSkin$2@4e4efb64[styleClass=cell indexed-cell list-cell]'null'

Button delete = FromsUtil.getButtonNoborder("", ImageFactory.getImageView(ImageFactory.delete_svg), 32.0, 32.0);
Button deleteUI = FromsUtil.getButtonNoborder("", ImageFactory.getImageView(ImageFactory.delete_svg), 32.0, 32.0);
delete.setOnAction(event -> {
dataset.setNotify(false);
for (XYSeries series : seriesList) {
dataset.removeSeries(dataset.getSeriesIndex(series.getKey()));
}
dataset.setNotify(true);
});
deleteUI.setOnAction(event -> {
Platform.runLater(() -> {
layerListView.getItems().remove(this);
});
});

This is my test code. After deleting the data in the first step, delete the data in the layer corresponding to the UI and keep reporting errors

Be sure you are using recent versions of jfreechart-fx and dependencies. The message duplicate children added suggests a JavaFX problem; in particular, "A Node may occur at most once anywhere in the scene graph."

Thank you for your reply, the problem has been solved, when javafx vbox remove child node, because I use lombok @DaTa annotation, it overrides my hashcode method, so remove fails!
