Ferret talk - Apr 2007 - strange behavior after switching to DRb server

After switching to the DRb server, I am experiencing strange behavior  
when sorting on score. My app was working as expected before the switch.

Both before and after the switch, my app sorts properly on other  
fields, such as date.

For sorting on score, I am using the following option  
find_by_contents option:

:sort => Ferret::Search::SortField::SCORE

Before switching to DRb, this worked very well. Afterward, I see the  
error below. (Resource is my model).

Any ideas?

Thanks (again...)
John

I had to build custom marshalling routines to support sort fields and it
seems I missed that one.

Adding this line:

return Ferret::Search::SortField::SCORE if string ==
''<SCORE>''

before line 142 in acts_as_ferret.rb should resolve the issue. Or get
the latest aaf from trunk.

Great, thanks Jens.
