Hey all,



I ran into a strange problem with the StrataFrame Business Object Mapper. When I try to configure my business project by clicking on the "Configure Project" link, I get an error message that says "Invalid column name 'proj_db2connstring'." Before going into the Business Object Mapper, I had debugged the project and set the application's database settings there with no problem. Indeed, I don't see any such column in our StrataFrame database. Any ideas what could be wrong? Here's the entire stack trace of the error if it helps any, and thanks in advance.



SqlException

Invalid column name 'proj_db2connstring'.
