ObservedComponentFactory.newInstance() should return a default implementation
when the observed path doesn't exist yet
----------------------------------------------------------------------------------------------------------------------
Key: MAGNOLIA-3011
URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-3011
Project: Magnolia
Issue Type: Improvement
Components: core
Reporter: Grégory Joseph
Assignee: Grégory Joseph
Fix For: 4.3
ObservedComponentFactory.newInstance() currently returns null when the observed
path doesn't exist yet. It should return a default implementation (to be
configured) or some form of null proxy (see for example [Proxytoy's null object
proxy|http://proxytoys.codehaus.org/apidocs/com/thoughtworks/proxy/toys/nullobject/package-summary.html])
so that client code can always keep a reference to the observed singleton
without having to care about it's state on the repo, thus making the
observation/factory system entirely transparent.
