Thanks for the reply (sorry: managed to reply twice). It's IB v2.
An older version of IB sounds feasibly yet we have sql maps that use similar
constructs, i.e <isnull> nested within <iterate> elements and accessing
properties on instances stored in maps. Most perculiar. I cant get it to
work and will probably have to resort to tortuous SQL to get the results I
need
