Checkboxes in a combobox popup

I am displaying checkboxes in the popup of a combobox via custom cell
factory. Only problem is that a click on the checkbox actually hides the
popup, even before that checkbox was selected. As I can see, the
combobox skin has a MOUSE_PRESSED event filter which hides the popup.
Current workaround is:
- get the listview from the combobox skin
- set a MOUSE_PRESSED filter on its parent
- in the filter detect a click on a checkbox (sets a flag)
- override combobox.hide, ignore the hide if the flag was set before
The other workaround is to make listview think that the click was on a
scrollbar by adding "track" to the styleclasses of all checkbox skin
nodes. Then the listview would ignore the click, too.
Both options seem to be... less optimal. Any other idea?
