Come on :)
I'm using rich:dataScroller because t:dataScroller produced exception when using "back" in a specific case, which is avoided in richFaces. Maybe I can disable ajax processing "somehow" ?
try please to use ignoreDupResponces="true" on dataScroller. ;)
This indeed helped a bit, but the problem is still there.
Also when trying to reproduce the problem I once encountered an ArrayOutOfBounds (getting incorrect row) exception, which normally (normal clicking) is not there. Couldn't reproduce that one though...
