I am joining a layer with a DBF on the field "ID", and am seeing this as =
a result of a query:

a.. Record 3663 (34): [[IDDBF]]
a.. Record 3663 (34): [[IDDBF]]

where IDDBF is the ID column in the DBF file. You can see from the query =
template below that the ID and RGE fields from the shapefile are coming =
across correctly, while the data from the DBF field is not appearing:

----- join.html -----
<li> Record [ID] ([RGE]): [IDDBF]<br>

According to =
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?MigrationGuide, this =
release was to have restored one-to-many processing.

My join template contains just the single line: [join_twps], where =
'twps' is the NAME of the join.

Has anyone worked this out yet?

Also, if the fields in the layer and the DBF are named the same, how do =
you differentiate the layer from the DBF field? Perhaps I am missing a =
part of the syntax that points to the correct data...

Thanks,
Chris
