Pessimistic Locking Plugin Breaks ActiveRecord::Base.count()

Rails
1

After installing the PessimisticLocking plugin I noticed that
ActiveRecord’s count method no longer works (see below). If I remove
the plugin it resolves the problem.

I need both. Any ideas?

I have also read that Pessimistic Locking is now baked into ActiveRecord
in Edge Rails. I have tried Rails 1.1.2 and 1.1.4 and that doesn’t seem
to be the case. Any idea when it’ll be in a production release?

Hi Don,
No ideas about the issue itself.

Edge Rails contains latest bleeding edge love to Rails and is the
target of new improvements. The 1.1.* series are instead a STABLE
branch of Edge Rails to which only bug fixes and minor non-backward
incompatible changes are committed.
From the RoR weblog: "All of the new features we’ve been working on
over the last couple of months will become available in 1.2.0, which
is scheduled for “soonish”.
Cheers.
