Paint problem with ScrollPane Accordion panel that has a columnHeader.
I have an accordion that includes ScrollPanes as panels. The ScrollPanes
has a column header with some checkboxes and a TreeView as the view. If
I scroll the view vertically, the background of the column header gets
painted with the information from the treeview that was supposed to be
scrolled out of view. When I hover the mouse over it, some parts gets
repainted correctly, but not all. Kind of hard to explain, so I created
a small screencast:

Am I doing something wrong or could this be a bug? Seems the mic on my
notebook is toast, the sound dissapears some places, but the video
illustrates the problem :)

Yeah absolutely, the workaround is good enough for me. I'll create a
minimal test app and submit a ticket as well :)

I haven't looked at any of the code, but it does look like a bug in the
screen cast.
Some components (or renderers?) allow the background colour to be set to
'null' which results in no background being painted.
It sounds like that might be the case here. Hopefully the workaround of
setting a background colour is OK for now.
Feel free to create a JIRA ticket - but please attach a small app
demonstrating the problem.

Setting the backgroundColor in the header seems to fix the problem:
getStyles().put("backgroundColor", Color.WHITE);
But still - the view isn't supposed to paint where the column header is
anyway, right?
