Statusbar question

I'd trying to configure separate, different statusbars on each of my two
screens. I use statusbar_workspace, and want it to display each screen's
workspaces on that screen.

I added a create in my cfg_statusbar.lua, so it looks like:

------------------------------------------------------------------------------
mod_statusbar.create{
     screen=0,
     pos='bl',
     fullsize=false,
     systray=false,
     template="[ %date || %workspace_pager ] %filler%systray",
}

mod_statusbar.create{
     screen=1,
     pos='bl',
     fullsize=false,
     systray=false,
     template="[ %workspace_pager ] %filler%systray",
}
------------------------------------------------------------------------------

The problem is, the workspace_pager that's shown on the screen1 is
actually a copy of screen0's pager, and is therefore useless. How do I
fix this?

Thanks much in advance!
