Ok. But I don't think that is the issue here is it? For this case (as I understand it), the thing that is building the BeanMetaData just needs to do: builder.addInstallCallback(method, someGeneratedName); The part I don't understand is why it has to get more complicated? Why do we need lots of new interfaces or methods when the thing creating the BeanMetaData is the one that knows what the generated names are? Like I said above, if you don't know what the generated name is how are you going to uninstall it when it is no longer required?
