--------------------------------------------------------------------------
Key: NXP-4700
URL: https://jira.nuxeo.org/browse/NXP-4700
Project: Nuxeo Enterprise Platform
Issue Type: Bug
Affects Versions: 5.3 GA
Reporter: Anahide Tchertchian
Assignee: Anahide Tchertchian
Fix For: 5.3.1
After errors, core session can be invalidated and null => use safer code in tag
templates to handle this case, see stack trace.
