--------------------------------------------

Hello Chunrong.

Could you try your reproducer on new Harmony build. I easy reproduced that issue on build r563769, but that issue doesn't reproduce on r566078.

Thanks,
Igor

>  The ScrollPane can not be displayed unless an extra valid event happens. For example, some keyboard events,  mouse moving in, etc.
