Liferay versione 6.2.0 CE GA2
When we mount a CMIS repository that doesn't support document versioning Document Library throw a nullpointer that block folder navigation.
1) In a different tomcat deploy chemistry-opencmis-server-fileshare-0.11.0.war downloaded from chemistry site
2) As described in the documentation  set login by screenname and session store password property
3) Logout from Liferay if you have login at startup by email address instead of screenname
4) Add the repository using AtomPub (the password of liferay user test need to be "test" because the default password for chemistry is "test".
