Based on what you posted in another thread this is not a problem with data source extensions.  You mentioned in that other thread that you want to access one local database and one remote database.  To do that you can use two separate Entity Managers - one for the local DB and the other for the remote one.  There's a parameter called EntityServiceOption which you pass in the EM constructor to tell it whether it's going local or remote.  You can read more about it in the "Business Object Persistence - Advanced" chapter, but the signature looks like this:
 
public EntityManager(bool shouldConnect, String dataSourceExtension, EntityServiceOption entityServiceOption);
 
Next problem, about the error message you're getting - First, it says that a default IdeaBladeconfig is in use; this means that either the ideablade.configuration section wasn't found in the config file or it was invalid.  When a default IdeaBladeConfig is in use  - which means DevForce built one up dynamically, the connection strings which may have been present are ignored.  (We do have an open bug report for this, but the problem is easily worked around.)   The debug log will have more information on the config file probing, so I would look at both the log and the config file next to see what's up.

I’m using v 6.0.1 I cannot get an Entity manager to connect when using more than 1 database. It gives the below error:

IdeaBlade.EntityModel.EntityServerException was unhandled

  Message=Key 'GTDMENTITYMANAGER': Parameter 'connectionString' is not valid. String arguments cannot be empty.

Parameter name: connectionString A default IdeaBladeConfig is in use and does not contain either connectionStrings or EdmKeys. Ensure a valid configuration file containing connection information is present, or implement a custom IDataSourceKeyResolver.

 

Has anyone tested this in version 6.0.1?

This particular problem affected only Silverlight when using data source extensions.  If that's your situation then it could be the cause of whatever error you're seeing.  The problem was fixed in 6.0.2.

Is this also why I’m getting errors when trying to access a second entity manager?

 

I’m in desperate need of being able to do this.

Is the DataSourceKey functionality available in the current release of DevForce 2010?  My custom version of IDataSourceKeyResolver never seems to be passed the keyExtension parameter and anytime my silverlight app accesses an EntityService.svc file, it's never of the form EntityServer_Extension.svc/sl...it's always just EntityServer.svc/sl. 
 
I've looked through the help and it seems like the pertinent sections are either "Not Converted" or "Coming Soon".  This leads me to believe that this functionality might night have made the cut for the RC.  If that’s the case, when do you expect this functionality to be restored?
