Description Mark Christiaens

2011-07-15 09:57:56 EDT

Build Identifier: 20110615-0604

When a clean build occurs then ResourceDescriptionsBasedContainer.descriptionsChanged(Event) receives deltas that have delta.getNew () == null.  That null enters the uriToDescription map.  That in turn causes getResourceDescriptions() to return an Iterable containing nulls.  That causes an NPE in for example  org.eclipse.xtext.resource.containers.FilterUriContainer.getResourceDescriptions().

Reproducible: Always

BTW, I'm trying to inject my way out of this but I notice I need org.eclipse.xtext.resource.containers.ContainerState to do so.  That class is package private.  Is that intentional?

No, the package private class is not intentional. Fortunately it's easy to implement (read: copy) the IContainerState on your own :-/
