Trinidad partial rendering not working correctly when used with Spring Faces

Trinidad's partial rendering features don't seem to be working correctly in combination with Spring Faces. A JavaScript error similar to the following is being raised in the browser when the response is returned:

["Invalid PPR response. The response-headers were:\nServer: Apache-Coyote/1.1\nPragma: no-cache\nExpires:..."]DebugCommon1_2_7.... (line 16422)
["Error ", TypeError: responseDocument has no properties message=responseDocument has no properties, " delivering XML request status changed to ", function()]DebugCommon1_2_7.... (line 16422

I was able to reproduce this in a simple Trinidad test project.
