Hi,

I'm facing a problem with a new project I generate with the Xtext wizard from an existing Ecore metamodel. Actually, the generated project works as expected except that the grammar editor does not recognize the imported EClasses so there are lots of annoying false error markers and auto-complete does not work, what makes editing the grammar quite inconvenient.

The problem can be reproduced by importing the attached archive as existing projects and choosing organization.genmodel for the nex Xtext project. The entry rule should be OrganizationData.

I'm using Xtext 2.10 in Eclipse Neon. Any ideas why it goes wrong?

Thanks in advance!

Gábor

simply configure xtext nature to the project containing the ecore
(righclick, configure, convert to xtext project)

Great, thanks!

It would be useful if this requirement on the existing Ecore model were documented in the "EPackage Import" section of the documentation. Even the project wizard could check if the project containing the Ecore model has the Xtext nature and display a warning or show a dialog that asks whether I want to add the Xtext nature to that project.
