Integer parameters in URLs don't work

[ebroder]

...or at least, I think that's what's going on.

The "Version" parameter for GetTrafficPolicy is encoded in the URL (the path is /2013-04-01/trafficpolicy/{Id}/{Version}). However, Version is specified to be an integer. It seems like any version number I pass in gets coerced to an integer, which in turn causes an exception when the REST handlers attempt to escape the version before interpolating it into the URL.

This appears to happen regardless of whether I pass a string or an integer for the version parameter:
