Since this is similar to JTable where issue is not seen and the cellrenderer and editors are used, I guess we should follow the same approach as it is being done in JTable as below and set the renderers and editors before the UI..

https://github.com/openjdk/jdk/blob/49176e322bbb9ed1ef2f534b949b937770b54162/src/java.desktop/share/classes/javax/swing/JTable.java#L3697-L3727

Other which does not use this renderers and editors we can skip setting UI after for the timebeing..
