Hi ara (Ara, a, ... which is the best salutation?),

There appears to be an incompatibility between arrayfields and active
record dynamic finders.

I've filed a bug report here:

http://rubyforge.org/tracker/index.p...1024&atid=4025

but I'm also posting it here to get a wider audience.

I'm using rails 1.2.3. After loading arrayfields 4.1.0 the active
record dynamic finders "find_by_ ..." are broken.

Here's a simple test showing the dynamic finder working, requiring
arrayfields, and then the dynamic finder stops working.

$ script/console
Loading development environment.
