I found I had to use the <s:set> tag to set the object in the request
scope before displaytag could "see" it, since displaytag doesn't know
about the Value Stack (maybe it should?). Confusingly, displaytag
gives you that message if it can't see the variable you're
referencing, as well as if the variable is empty.
eg. <s:set name="items" value="items" scope="request"/>

<display:column property="prize" />

the result is:
Nothing found to display.

It pays to really spend some time looking over existing
documentation;
it's
often quicker than waiting for someone on a list or forum to
answer.

jim,
I found this example
http://displaytag.homeip.net/displaytag-examples-1.2/example-paging.jsp?d-49653-p=1
it says "Ok, you have made a query that returns you back a
list of 120
elements, but you don't want to show the user all 120 items at
once,
you
want to allow them to page through the results (pretend 120 is
really
1200
or 12000)."
they are iterating through a long 12000 record list and then
just
putting
that into pages. What I was looking for was something that
would show
50
results of 12000 on first page then when NEXT is cliked, it
against
goes
to
DB to get next 50 records.

Note that the contents of this page are actually fairly
freakin'
horrible
and should not be done on a grownup application. But the
instructions
are
right there and easy to find.

then again I go to the DB to fetch next set of 50 records.
