Description Kenn Hussey 2010-04-15 13:06:42 EDT

Attempting to create a new file (e.g., an Ecore model) without first selecting a container (project or folder) now results in a null pointer exception. This is because the new isFilteredByParent() method in WizardNewFileCreationPage does not guard against the possibility that 'containerPath' might be null.

Here is a representative stack trace:
