OLAP API 10G Source objects - drilling

Question

I have a block of code that works in 11G to set a point in a dimension and then lists its children
StringSource top = (StringSource) mdmDim.getSource();
Source topp = top.selectValue("TOTAL_CHAMPION_HIER::TOTAL_CHAMPION::62404");
//Source foo = dim.join(hier.getSource());
Source foo = hier.getSource().selectDescendants(topp,hier.getParentAttribute().getSource());
// Create a Cursor for the query.
Source bar = foo.join(foo,mdmDim.getValueDescriptionAttribute().getSource());
But when i port this code over to 10G, it compiles just fine and the docs make it look like all the calls do the same thing, but no i am getting a mismatched dimension when i create the cursor, it says my Dim is unmatched and i think that is because my topp Source is coming out with no data.
Any clues?

AH replying to my own thread, tacky
Here is the gist of what i want to do in 10G through the API.
I have a short key ie "Y2005" instead of "CALENDAR::YEAR::Y2005",
i have the MdmHierarchy and MdmDimension and i want to produce a Source objetc that will tell me the children of "Y2005" in my MdmHierarchy, which is a MdmLevelHierarchy. And returning the shortdescription would be nice. That is what i am trying to do above.
