Paginator, like the name sort of suggests, creates page links (e.g. 234 5 678) between prev and next page links.

Oh jeez, my bad, I just figured out how this is supposed to
work, I didn't realize it did most of the work for you.
What's the paginator all about?

Ok,
I tried it by binding like so:
pageCountVar="#{myBean.pageCount}"
pageIndexVar="#{myBean.pageIndex}"
Both Integers, but I get this.

Can someone explain how those are supposed to work? My
assumption is that they are just like sortBy and ascending in
x:dataTable where if I click on it, those variables get set
appropriately. For example, if i click on forward one in the data
scroller, I would expect the pageIndexVar to be incremented by one. Is
this not the case?
The classcast is here, because it's expecting a string.
if (_pageIndexVar != null) return _pageIndexVar;
ValueBinding vb =
getValueBinding("pageIndexVar");
return vb != null ?
(String)vb.getValue(getFacesContext()) : null;

I haven't tried pageCountVar, and I don't see
how binding it to a
property would be useful, as the bean should
already be the source of
the table data and thus should know the count,
but I'm using
pageIndexVar exactly like that and I don't need
to guess; I *know* it
works.

And it works? i guess it does't. To
reset the dataTable to
the first page, or any page, there is
the "first" attribute
for the dataTable which can be bound to
a bean property.
The attributes "pageIndexVar" and
"pageCountVar" of the
dataScroller are like the "var"
attribute of the dataTable,
you can use the value of them inside the
dataScroller.
<x:dataScroller id="scroll_2"
for="data"
pageCountVar="#{myBean.count}"
pageIndexVar="#{myBean.index}">

Is there any reason pageCountVar
and pageIndexVar
can't be
bound to a value like sortColumn
and sortAscending
are in the
x:dataTable ? for
example:
<x:dataScroller id="scroll_2"
for="data"
pageCountVar="#{myBean.count}"
pageIndexVar="#{myBean.index}"
