 yep.  patch #16401 - don't use the cut-down version that the other
company who are doing "vala" bindings are using - use the version
that  i've worked on, until they support the "full" DOM bindings.
better yet, just grab the code from the git repository i'm maintaining
- http://github.com/lkcl/webkit/tree/16401.master

i do searches for the words "ajax" and "javascript" and "pyjamas"
using groups.google.com occasionally, and pick things up -
eventually :)

 it was - however i've since found three other projects (including
python-hulahop, the best other alternate candidate).
