Steps to Reproduce
1. Add a new Organization
2. Open JXplorer
3. Expand "Communities" and then the Organization that was just created
4. Assert "com.liferay.portal.NoSuchGroupException: No Group exists with the key" thrown in the Liferay logs and JXplorer states "Unable to perform Read entry operation."
The issue seems to be that it is searching for a group with a key of "test" but since it is an organizational site, the key is "test LFR_ORGANIZATION".
