Hi there: Since some weeks ago we are experimenting some exception randomly: https://issues.apache.org/jira/browse/WAVE-307 (see RemoteWaveViewService.getServerVersion) that makes WIAB very unstable/unusable because we cannot edit or reply some waves, or we lost editions, or access to that wave with the message "No conversations in this wave".
I'm very lost looking in the code and logs, also because I cannot reproduce it in my development workspace. Can anybody more experienced help on this, giving some info, advice, reasons for that exception, etc? Maybe someone is looking already on it... Thanks, Vicente
