When setting the "model" attribute of a property edition element, if the "model" attribute of the property edition component has not been set, I get the following exception:

The Eclipse EEF team has worked over the past few months on a brand new runtime using a reflective approach which can be used more easily with Eclipse Sirius. Since we do not plan to continue to work on the old runtime and its code generation approach, I will close this issue for now.

If you want to contribute, you can reopen this issue and submit a contribution to the project thanks to our Gerrit: https://git.eclipse.org/r/#/admin/projects/eef/org.eclipse.eef
