Hi

in Xtext 2.0 error and warning methods which used to get an integer
representing an EStructuralFeature now require an EStructuralFeature
(and this can be dealt with by using the Literals of the generate EPackage).

(by the way, the documentation concerning Validation has to be updated I
guess, since it still uses integers).

However, what If I don't want to specify any EStructuralFeature, but
only an EObject? In Xtext 1.0 there used to be such error/warning
overloaded method but this is not available anymore in Xtext 2.0.

thanks in advance
Lorenzo

Hi,

wasn't it always necessary to provide the "int" for the feature, only that you could put there what you wanted?

As a workaround for your use case (which I don't quite understand as I'd rather not mark too much) you could make the container of the object X the error source and use feature that contains X as the required feature.

Hi Alex,

the validator handles 'null'-features gracefully.

Regards,
Sebastian
