First, I don't understand why datascroller is rendered so:

|<< <<|<<| this is blank but works as prev button |1|2....

why the prev is rendered as blank cell??
This happens in my test but also in the online demo..

Another thing is that renderIfSinglePage="false" doens't work (it always render the datascroller) .

The last question is..how to hide the next button the user is on the last page, for example?
