scale and query problems

Sun Feb 4 17:36:44 PST 2001

Daniel,
A few weeks ago I asked this question, but really didn't get around to
looking into the problem furthur until now.  However I am still have the
same problem as before.  I am sure that my layers are setup properly and
have included the mapfile that I am using below this message.

Your suggestions would be greatly appreciated.

Robert,

This probably has more to do with your .map layers setup than with
MapScript itself.  Are all the layers you want to query with STATUS=ON,
and do they all contain a QUERY object?

We've used queries with multiple layers before and I don't remember
noticing a problem... but a bug is always possible.  If you're sure that
your layers are setup properly, then please send me your .map file and
I'll try to reproduce/fix the problem.
