SSAS, C#, and AMO: Creating Linked Measure Groups

Hi,

I'm using C#, SQL Server 2005, and AMO to create a series of cubes. Then I want to create essentially what whould be a "Parent Cube" that would contain linked measure groups from all the cubes I previously created. I can create the linked measure groups, and when I browse my "Parent Cube" in the immediate window in Visual Studio 2008 I can see all my linked measure groups. However when I go to Update() the cube with the linked measure groups I get an error stating that my cube contains no measure groups. So I'm confused because I can browse them in the Immediate window and through the watch window.

Here's the C# code I'm using to generate the linked measure groups:

        public void CreateLinkedMeasures(string[] cubeSuffixes, string cubePrefix)
        {
          
            foreach (string suffix in cubeSuffixes)
            {
                string childCubeName = cubePrefix.Replace("_LINKED", "");
                Database localDatabase = _server.Databases.FindByName(childCubeName + "_" + suffix);
                //_cube has the measure groups I want to link to.

                _cube = localDatabase.Cubes.FindByName(childCubeName);
               

                foreach (MeasureGroup mg in _cube.MeasureGroups)
                {
                    string name = "BASE_" + cubePrefix + "_" + suffix;
                    MeasureGroup lmg = _linkedCube.LinkMeasureGroup(mg, localDatabase.ID, name);
                    lmg.Source.CubeID = _cube.ID;
                    lmg.Source.Persistence = PersistenceType.Metadata;
                }
            }
         
        }
       

This method appears to work because I can see them added to the _linkedCube, but when I run _linkedCube.Update(); I get an error stating that _linkedCube has not measure groups.

Any clues on what I'm doing wrong?

Thanks!
