Ok, this is different then, you have my full attention. So lets recap:
- you use Squeak 3.9, correct?
- you use SeasideInstaller from SqueakMap, which version, 2.8beta?
- you use WAKom
- /seaside/tests/alltests the "Encoding" tests fails?
Anything else? I just did all this for Windows XP and a 3.10.6 VM and
the tests work. Can you confirm that you have KomHttpSever-pmm.2 and
Seaside2.8a1-pmm.476? This is configuration that is really supposed to
work. If this really doesn't work for you then I need your image
because otherwise I'm not able to reproduce this bug.
Cheers
