Hi
using RAP 1.0.1 sort on virtual table viewer works better :)
However there is still a problem when the amount of data showed in the
table can not be displayed at once (is more thant the visible part of
the table)
for this I have created bug no. 211790 it contains the steps and patch
to reproduce on demo application
Cheers,
Val
