Hi Frank,
If it worked with an older Version, my guess is that you generated the
token resolvers and afterwards changed the type of an attribute in the
Ecore model. Maybe... its hard to tell without having the full projects.
But if it is working for you now it should be fine. :) If you find out
what caused the problem let us know.
In general everything in your 'resource' and 'ui' projects is
overridden. So you do not have to delete them.
Exceptions are all classes in the 'src' folder (in which token resolvers
are placed by default). Other artefacts can be marked as not-override by
using the 'override<ArtifactName>=false' options.
This is also explained in the EMFText User Guide.
Cheers
Jendrik
