Hi Eric,
If you are using an official JastAdd release it is highly unlikely that
this is caused by a problem with the JastAdd2 version you are using,
since the last release was a couple months ago and you should have seen
the same error before now if nothing has really changed in your code.
The error reporting by JastAdd2 can obviously be improved here, so I
have jury rigged a JastAdd2 jar that prints improved error messages for
specifically multiple declarations of inherited attributes. Try to
compile with this JastAdd2 version and hopefully we can shed some light
on this mystery!
