Long story short:
I have a BDC application definition in my sharepoint 2007 server, which is pulling data from a SQL server.
Some of this data is the Employee Name.
What i'm trying to do, is that when a user is writing a portion of the employee name in the BDC column (in the custom list) and then clicks 'Check Names', it will show him a list of the available names it found. (Like this user column type:) http://img577.imageshack.us/i/goodj.png/
now, what happens in real life when using BDC, is that i dont see the list of available users.
Any help solving this issue would be greatly appreciated!
