AssertionError from scala.tools.nsc.typechecker.SuperAccessors on Build
real branch : wip_exp_backport
scala version : 2.8.1.final
clean as no effect.
Same error after, fixing all errors repported by build from command line (maven), and restart the IDE
Same error but on an other part of the code if I comment the method with the code indicated.
As the build failed (presentation and builder), I've got a useless ide :

I would like to know if there is some possible workaround (suggestion), I can try to implement in nsc.interactive or in sdt.core ?
I import the "failing" project into my Test eclipse workspace for scala-ide. And was not able to reproduce (I've got other error).

Hubert, can you please have a look?

David, is there any chance I can also get the other sources that are needed to compile this code? (You import some other packages).

Yes, I just share the project into github https://github.com/davidB/reabuilder

I define one package or package object per file
