Is it possible to use Sirius without generated java code? [message #1719077]

Hi,

I am writing a research paper and I need to confirm something. Some editors, such as the reflective EMF tree editor, are able to work with Ecore models that have no generated model code. I want to know if this is possible with Sirius, or if the model code generation step is necessary.

I know it is possible to load an .ecore file from the workspace using the 'Load Resource' action, but it throws an error telling me that one of the classes does not exist:

Toggle Spoiler

The error goes away if I generate model code and load it into a new Eclipse workbench.

I am unable to find any information on whether this is supposed to be possible or not. If anyone knows for sure or has a source confirming whether it is, then it would help me out a lot. Thanks.

Version details:
Eclipse Modeling Tools

Version: Mars Release (4.5.0)

What happens if you deactivate live validation and try to run it?

You need to generate java code to open an EMF model with your own type
EMF provides the Reflexive editor to edit .ecore models. If your ecore
model contains only instance of the Ecore metamodel you should be able
to open it without error with the reflexive editor

It doesn't show up in the Viewpoints Selection dialogue so I was unable get any farther than this.

Thanks, that's good to know.
