extending grammar: error in generated Semantic Sequencer? [message #821890]

I have two languages, one extending the other.

When I regenerate the extending language there is an error in the generated AbstractExtensionSemanticSequencer.java.

Looking into the file, the error is because it references the sequencer from the base language incorrectly. Specifically, the generated file refers to

BaseSemanticSequencer

instead of

AbstractBaseSemanticSequencer

Manually changing the generated file throughout (i.e. to use AbstractBaseSemanticSequencer) removes the error. Of course the file is replaced next time the generator is run, re-creating the problem.

The base project appears fine (no errors/warnings, all unit tests run, can launch in runtime IDE). The extension project is similarly fine when the manual fixes are made.

Any suggestions appreciated...

Thanks.

Hi Scott,

you may want to set generateStub = false for the SerializerFragment to
true in the workflow that generates your language infrastructure.

Regards,
Sebastian
