Attempt to delete view table results in ClassCastException

Created a View Model, then added an empty Table via the Create Table dialog.

then when I tried to delete, it nothing happened (didnt delete). I got the following exception:

!MESSAGE java.util.ArrayList cannot be cast to org.eclipse.core.resources.IFile
!STACK 0
