I created a bug for this
http://www.openlaszlo.org/jira/browse/LPP-6668
What is really weird is that I put some tracing in, and the bug is
happening on the failing datapointer
because when it sets is xpath to "ds1:/persons", the name
canvas.datasets['ds1'] is unbound,
(but canvas['ds1'] is bound!). How can that be? Why is the other
dataset, ds2, behaving properly?
Who is responsible for setting canvas.datasets[DSETNAME] ? Why would
it be getting set
in one case but not the other?
