Description

Since today I've faced this NPE for a second time:

java.lang.NullPointerException
at org.apache.isis.applib.services.exceprecog.ExceptionRecognizerComposite.injectServicesIfNecessary(ExceptionRecognizerComposite.java:120)
at org.apache.isis.applib.services.exceprecog.ExceptionRecognizerComposite.recognize(ExceptionRecognizerComposite.java:79)
at org.apache.isis.viewer.wicket.viewer.integration.wicket.WebRequestCycleForIsis.errorPageFor(WebRequestCycleForIsis.java:184)
at org.apache.isis.viewer.wicket.viewer.integration.wicket.WebRequestCycleForIsis.errorPageProviderFor(WebRequestCycleForIsis.java:157)
at org.apache.isis.viewer.wicket.viewer.integration.wicket.WebRequestCycleForIsis.onException(WebRequestCycleForIsis.java:148)

It is because org.apache.isis.applib.services.exceprecog.ExceptionRecognizerComposite#container is null and it is not possible to inject the dependencies of the delegates.
