Exception thrown when starting mapping from scratch in VS Code #147

Closed tpluscode closed 6 months ago

tpluscode commented 11 months ago

I found that it was impossible to start a fresh mapping in a project. When I added the first .xrm file the xtext server would crash. I could fix this by adding any content to the mapping and restarting the IDE
