How to provide a different error message for 'Couldn't resolve reference to..' error [message #957897]

Hello,

I have a grammar that specifies how a Statemachine should be defined. It should contain only one start state.

In the dsl generated, if a start state is given a value 'dummy' which is not the name of any of the states within the statemachine, an error 'Couldn't resolve reference to start state dummy' is displayed.

I want to change this error message generated by Xtext in the dsl and provide custom error message. How do I do that?

Please help..

Thanks in Advance,
Latha

Hi Latha,

subclass org.eclipse.xtext.linking.impl.LinkingDiagnosticMessageProvider and bind it by overriding bindILinkingDiagnosticMessageProvider() of your runtime module.

Kind regards,
~Karsten
