Creating a New Feature Join

[Sacha Genoud]

In Mapguide Studio-Manual there is a Section 'Creating a New Feature 
Join'. But in the Application you don't have this as
it is described in the manual. When i use 'Join with other feature 
sources (optional)' in the 'SDF Feature source' Tab to ODBC
Access Database i get an error: 'Unhandled exeception has occoured......'

Do i something wrong or is it bug?
