Hi

I'd like to customize the error message concerning 'this' (and 'super'):
in my DSL I don't want to support neither of them, since basically,
internally, everything is a "static context". So, I'm happy with usage
errors being detected, but I'd like to customize such error.

I see that error is generated in
org.eclipse.xtext.xbase.typesystem.internal.FeatureLinkingCandidate.validate(IAcceptor<?
super AbstractDiagnostic>) which I guess is not meant for customization
(there's no injection there).

Would it be better to perform customization at another level, such as
scoping? If so, which class is ideal for such customization?

thanks in advance
Lorenzo

Hi Lorenzo,

we have plans to make it easier to customize xbase linking validation
but for now you may want to specialize the IDiagnosticConverter and
fixup the wording there.

Best,
Sebastian
