      Exception
      java.lang.IndexOutOfBoundsException: 2 out of 0..1
      at org.zkoss.zul.Radiogroup.getItemAtIndex(Radiogroup.java:140)
      at org.zkoss.zul.Radiogroup.getSelectedItem(Radiogroup.java:215)
      at org.zkoss.zul.Radio.fixSiblings(Radio.java:174)
      at org.zkoss.zul.Radio.service(Radio.java:258)

      Expected Result

      No exception

      Debug Info

      Only happen if the radio are descendant, but not direct children of the radiogroup
      case 2 (direct children) doesn't show the issue

      Root Cause

      _jsel is not updated when removing a descendant radio
      possible additional safety after fix: check if _jsel < radiogroup.getItemCount() in getSelectedItem()

      Workaround

      attached RadioGroup override class for ZK 8.5.0
