There is couple of issues with renaming source model that is referenced in some view model.

I am using project Dataroles_project.zip (attached)

1. I tried to rename Products_source.xmi to Products_source1.xmi

• this generates some error in log but it works...

2. Rename Products_source1.xmi to Products_source2.xmi

• this fails to rewrite the reference in view model
• I changed the references manually

3. Remane Products_source2.xmi to Products_source3.xmi

• this deletes tables from view model

This problem occurs only on Windows, Linux is fine...
