problem in joind feature

[farzad ghavam]

Hi to all,
I have the some problem, please help me.

I do the following steps in my map in the MapGuide Studio:
  1.I create an odbc data connection (access database)
  2.load a sdf file and at the bottom of this page in "Join with other 
feature sources", create a secondry join with that odbc data 
connection.
  3.I create a layer by this resource(set the data resource in 
liberary and set the feature class and geometry)
  4.When I use in "Filter applied to data" by sdf properties it is 
correct and work very good, but when I use a filed of table(this field 
is in table on odbc connection) it is not work.
