Java Development Tools

Question for Product Team:

When using a tableSelectMany component the developers guide does a good job of explaining how to get the selected rows using the getKeySet() method - ex:

Set keySet = getSearchTable().getSelectionState().getKeySet();

I have had to programmatically work with this Set and combine it with another set along with some business logic. I notice that the key values returned by getKeySet() are in the format:
"oracle.jbo.Key[keyvalue]"

I am using string functions to extract the keyvalue out of the KeySet. My question is whether the result will always contain the "oracle.jbo.Key[]" part since my code is now dependent on it. Or, maybe there is a better way to just get the keyvalue?
