[mapserver-users] getfeatureinfo problems

[DeDuikertjes]

List,

Thanks to Bart van den Eijnden the problem is solved.
I used a "using unique" clause on a column which was unique, but not 
integer.
So I now create my postgis tables with a CREAT TABLE .... WITH OIDS

and I use a "using unique oid" clause in the DATA statement.

As often, details do matter.

Thanks for all the responses and efforts.
