PsiElement.getContainingFile() is @Nullable

Hello Sascha,

PsiDirectory, PsiPackage

When would that typically happen? Can PsiElements exist without a file
and under what circumstances would I come across such an element?

Thanks,
Sascha

Thanks! (A little note in the Javadoc wouldn't hurt though ;))

Also, I believe I've seen it return null inside a completion handler.

Wasn't that about PsiElement.getContainingFile().getVirtualFile() == null vs.
PsiElement.getContainingFile().getOriginalFile().getVirtualFile() ?
