Форуми / Cotonti / Support / Default value in extra fields for pages not working?

I've submitted a ticket for this issue. I'm investigating it also but haven't found the problem so far.

Update: I've released a fix for this. See changeset 1235.

The problem was with the page being redirected after a failed submission, so any request variables were lost. All other (default) fields are getting their values from the import buffer, but the extra fields were not.
