David,
Looking at the xml, you have added a "clean_command" to all the
properties which is "RemoveAllInputs". CleanCommand is called before a
property is pushed. So before each property value is pushed all other
inputs are removed. And hence the error.
If your filter only takes 1 connection per input port, then simply
replace all AddInputConnection commands by SetInputConnection and
remove the clean_command attribute all together. I've attached a
modified xml.
