Done: issue 82722 http://www.openoffice.org/issues/show_bug.cgi?id=82722

Well... I remember that I had crashes with a complex
implementation
(different listeners for a FilePicker with image preview) on
Winndows XP
using OOo build and "css.ui.dialogs.FilePicker" as
service name: the
user was using the system dialogs, and listeners seemed to
be crashing
OOo. So I decided to use ALWAYS
"css.ui.dialogs.OfficeFilePicker" as
service name.
For my experience, it seems like complex manipulation fails
if you don't
use OOo dialogs (OfficeFilePicker), and this even with OOo
builds, under
Windows!
Bye and thanks,
Ariel.
