no we have no dual slider out of the box.
b.t.w. you could specify more clearly the functionality you need and we could check if this could be done for example with components composition in some custom facelet.
The dual slider is like a min and max slider.
We can get the data range between the two slider edges.
The one slider indicates the minimum data value and another one slider indicates the maximum data value.
No it could not be achieved using just composition. So you could
1) vote for such component in our wiki
2) try to checkout our slider from SVN and customize it by yourself to your functionality
