exception when nesting rich:dataTables
i'm not sure if this is something i'm doing wrong, or if this is an actual bug. i'm trying to nest two rich:dataTables, one of which has a rich:datascroller attached to it. after a couple of clicks on the scroller my application crashes with an exception.
my jsp page:

my backing bean, pretty simple:
import java.util.ArrayList;
import java.util.List;
public class TestbedBean
{
public List getOuterTableRows()
{
ArrayList<String> retval = new ArrayList<String>();
for(int i=1; i<=30; i++)
{
retval.add(Integer.toString(i));
}
return retval;
}
public List getInnerTableRows()
{
ArrayList<String> retval = new ArrayList<String>();
retval.add("inner row");
return retval;
}
}
the exception (some stuff removed):

1. this problem goes away if i use an h:dataTable as the inner table. this is a viable solution for me, but i'd really prefer to be able to use two rich:dataTables.
2. this seems unrelated to my web.xml configuration. i've stripped out any richfaces parameters in my web.xml and it seems to have no effect.
3. the page renders fine initially; it only crashes when i try to scroll through the outer table. oddly enough, it will sometimes allow me to scroll once, but not a second time.
i'm using JBoss 4.2.2 GA, JSF RI (Mojarra) 1.2_08-b06-FCS, RichFaces 3.2.0.SR1, and Firefox 2.0.0.14.
i'm pretty stumped by this and i suspect that i'm doing something wrong, but i have no idea what that would be. pretty much everything else in my application works great, until i try nesting rich:dataTables. any and all suggestions would be greatly appreciated. thanks!
