IIRC, an NPE from tableRowsIterator is often due to referencing an
attribute of a related object in OGNL (e.g.
ognl:customer.address.street) when the related object (e.g. address)
is null.
HTH. If not, as Karthik said, please post the relevant source code,
page or component specifications and HTML.

Hi
I'm fairly new to tapestry and am trying to create an
implementation of the
IBasicTableModel interface so that I can paginate results and get
results
(from Hibernate via Spring) when I need them.
I've written my component but whenever I load the page I get a
ognlException
on the tableRowsIterator which seems to stem from a
nullPointerException
from getCurrentPageRows.
Does this mean that there's no data being loaded into the table
component to
be displayed? I must admit I'm not entirely sure what approach to
take to
try and solve the problem.
If anyone could shed any light on what's happening, or could give
me an idea
of where to start debugging this I'd be most grateful!
