Inconsistency between Data Source Designer and underlying code

I have 2 data sources that have recently been updated from SQL Express to full versions of 2005. The connection strings have been changed, and the changes appear in the code, but the data source designer still shows the SQLExpress portion of the connection string. This seems to be fouling up SSIS packages that are using these data sources. Has anyone else encountered this? If so, what can I do to fix this issue?Can you recreate them?|||Are you using configurations? If so, have you updated them to reflect the right connect strings?|||Turns out the problem was this: the project was checked out by the person who created the datasources. When he checked the datasources in, he did NOT check the project back in. The project's definition contained the incorrect connection strings. Once the project was checked in, that issue was resolved. Thanks for your responses.
