Handle UnsupportedOperationException for User implementation within the
Freemarker model/wrapper
------------------------------------------------------------------------------------------------
Key: MAGNOLIA-3037
URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-3037
Project: Magnolia
Issue Type: Improvement
Components: core
Reporter: Grégory Joseph
Assignee: Grégory Joseph
Fix For: 4.3
When Freemarker templates attempt to output properties out of
{{info.magnolia.cms.security.User}} instances which throw
{{UnsupportedOperationException}}s (typically
{{info.magnolia.cms.security.ExternalUser}}), this results in ugly exceptions
thrown all over the place. Since templates should anyway be aware of this and
provide fallback behaviour, our Freemarker wrapper for User could handle those
exceptions, giving templates the chance to handle absent properties. They
should be able to do {{user.myProperty!'default value'}}, for example.
