Hi,
The problem is, I guess, with TableScrollPane repainting method. As far as I
know it keeps it's last visible area in an Image object in JViewport, at
least when appropriate option is set.When I open one of my application's
windows, I get an NullPointerException (given below). Strange thing is, that
this happens only in one window ( and there are about 40 others) and only on
Windows 98 OS. I haven't noticed it neither on Windows NT 4.0 nor Windows
2000 Pro.
Even when I changed that repainting option to the one not using Image to
cache it's visible area, I got the same exception. Than what is the
solution?
ANY help would be appreciated.
Here is that exception:
