Quickfix for syntactical errors [message #1741766]

Hi,

I have customized the generated error messages for my language via ISyntaxErrorMessageProvider by the following:

public static val INVALID_VAR_IDENTIFIER = "INVALID_VAR_IDENTIFIER"

override getSyntaxErrorMessage(IParserErrorContext context) {
	val unexpectedText = context?.recognitionException?.token?.text
	if ( !(GrammarUtil::getAllAlternatives(grammarAccess.getGrammar()).contains(unexpectedText))) {
		if (context.currentContext.eClass.name == "Dcl_var") {
			return new SyntaxErrorMessage(
				"Identifiers for variables have to start with a lower case!",
				INVALID_VAR_IDENTIFIER
			)
		}
}

Now I want to add a quickfix for this, but I'm getting the error "The annotation @Fix is disallowed for this location."

@Fix(CeuSyntaxErrorMessageProvider.INVALID_VAR_IDENTIFIER) { }

how can I now add a quickfix for this IssueCode if this is not working? I haven't found any help on the documentation..

It's within the QuickfixProvider class

class CeuQuickfixProvider extends DefaultQuickfixProvider {
	@Fix(CeuSyntaxErrorMessageProvider.INVALID_VAR_IDENTIFIER) {
		
	}
}

@Fix(MyDslValidator.INVALID_NAME)
def capitalizeName(Issue issue, IssueResolutionAcceptor acceptor) {
acceptor.accept(issue, 'Capitalize name', 'Capitalize the name.', 'upcase.png') [
context |
val xtextDocument = context.xtextDocument
val firstLetter = xtextDocument.get(issue.offset, 1)
xtextDocument.replace(issue.offset, 1, firstLetter.toUpperCase)
]
}
