[Pywps-dev] Can't get XML output's execution ( pyWPS + Owslib )

Thu Jan 7 00:46:32 PST 2016

Mariano,
yes, the target XML shoule be updated (and always was) ... to debug assync
mode, it was always little bit tricky. First step is to make sure, your
process is really running in sync mode - is that your case or are you
facing some logs in error.log?
