Cannot Resolve A Package Path

I have a parent package - Main.dtsx that calls a number of child packages. I also use configuration packages as I must deploy the application across multiple environments.

Main.dtsx contains a single Ccnfiguration file - Child_Packages.dtsConfig. This contains the connection strings for all the child packages.

Each child package contains a single configuration file - Main.dtsConfig that contains a superset of OLE DB connections. That is no single child package uses all of the connections contained in main.dtsConfig.

Each child package will execute independently without error. However, when called from Main.dtsx, I get the following errors:

Error: 2007-08-15 15:44:22.93

Description: The connection "CRM" is not found. This error is thrown by Connections collection when the specific connection element is not found.
End Error

Description: The package path referenced an object that cannot be found: "Package.Connections[CRM].Properties[ConnectionString]". This occurs when an attempt is made to resolve a package path to an object that cannot be found.
End Warning


I have seen discussions that suggest that these errors occur where the connection in the config file is not found in the child package. Is there any way of suppressing this ?

Are there any simpler methods that allow me to change connections in each environment?

I suspect I will end up having to tailor config files for each child package, but I live in hope.
