Subject: Add 'no messages available' to empty inbox
X-Git-Tag: 2.0.99~65^2
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F98%2F68198%2F1;p=laas.git

Add 'no messages available' to empty inbox

Added a simple check to see if the list element had no children,
and if so, it would add a simple message saying that no messages
are available.
