Observers not working because of AR Plugins? (Rails = 1.2.3)

Hi list,

I've tried to implement a simple Observer to log changes to my objects. Whenever I try to enable the observer in my environment.rb, my application refuses to start.

Here's what's in my environment.rb:

Rails::Initializer.run do |config|    config.active_record.observers = :audit_observer end

It seems, that rails can't find the plugins used in the observed models. This was a problem in older rails version (see http://dev.rubyonrails.org/changeset/4684), but I'm using rails 1.2.3, so this is already included.

As nearly all my models ar using some plugins, what can I do to get observers working?

Here's the mongrel output:

ok, I was looking into the wrong version of environment.rb.

It looks like this:

Rails::Initializer.run do |config|   config.plugins = ["engines", "*"]   config.active_record.observers = :audit_observer end

I really wonder, why config.plugins = ["engines", "*"] is causing the error? Shouldn't all plugins get loaded before the observer gets activated?

When I put all plugins into that config.plugins Array, it seems to work. So, why does "*" does not work?
