thanks stepahn for your answer
i´ve replaced all the osgViewers by osgViews, but the problem is still there,
the databasepageloader goes away anytime we call the removeview method of the
composite viewer.
anyway, cloning the databasepageloader and then assigning it to the rest of the
views is working fine... maybe it´s not the best way, but it works and we are
under a lot of time pressure now.
what i find interesting is that there is no need to use the viewer for our
application, the view does the same thing for us. Our team hopes that there
will not be so much time pressure in 2-3 weeks and then i´ll test it deeply to
see if i can get rid of this little tricky method of cloning the dbpl using
views instead of viewers
thanks again for the reply
cheers
