Is the DatePicker component correctly visualized? Is everything working?

[malintha-induwara]

Yes its correctly visualized and everything is working fine except that exception. It seems like the exception isn't affecting anything it's just being thrown.

I created a simple JavaFX application and used DatePicker to record following demo. hope it helps you.

It does impact functionality. If you default the value of the date programmatically and click the icon, the calendar does not display the value of the defaulted date, instead it displays the current date. If you click the year dropdown, you will get this IndexOutOfBoundsException. If you select the year and month of the defaulted date, it will show the date is actually set. If you change the date using the UI, then it will jump to the correct date when the icon is clicked.

Unfortunately, there's nothing I can do right now.
All controls using VirtualizedFX 11.x.x should be ported to the new 21.x.x version to work properly
