Configuration no longer available to FacetDecorator during initialisation

[Robert Matthews]

Guys

A few weeks ago I created a facet decorator to localize my object via a 
wiki.  I created a FacetDecorator that decorates the Named, DescribedAs 
and Help facets.  In the constructor I set up a couple of properties 
using the IsisConfiguration object, accessed from IsisContext.  This 
worked fine.

This evening I've update the code and now it fails to get the 
configuration object, and my system now won't start up.

Caused by: 
org.apache.isis.core.commons.config.IsisConfigurationException: No 
configuration available

What is the reason for the configuration object no longer being 
available? Should the decorators have a initialization process?
