Whenever i try to open a components.e4xml file with the "E4 Visual Design Editor" i get the following class cast exception

java.lang.ClassCastException: org.eclipse.e4.ui.model.application.impl.ModelComponentsImpl cannot be cast to org.eclipse.e4.ui.model.application.impl.ApplicationImpl

The same exception is thrown when i create a new components.e4xml file using the "New Contribution Model" wizard. 

The components.e4xml can be opened with the "E4 WorkbenchModel Editor"

Visual Design Editor is a WYSIWYG editor. It can edit and visualize the entire e4 application. We have not investigated to edit in WYSIWYG way a component file.  

In the worst case, Visual Design Editor should enable to open the file without the WYSIWYG design capability. Outline view and properties view should work.

The bug needs to be fixed.
