Hi Folks, Made some progress. I removed the "Foo" routine (it was the last call I made to Export()) and the "Ping" routine I added using the above routine worked. So it would appear that each call to Export() overwrites the last, thus it is not cumilitive as I had expected. Now I'm focused on

Hi Folks, I have been trying to implement godbus's Export function to no avail. Looking at server.go (under the examples folder) is not very helpful as an inspection of export.go contains what appear to be cheater functions that enable the example to work. Rename "Foo" to "Ping and it fails.
