Model attributes calling helper function?!

I have a totally wacked problem going on.

I have a model attribute with the same name ("content") as a helper
function, and when I call "model.content", it's calling the "content"
helper function instead of the model's attribute.

This, of course, causes severe problems.

In our master branch, this is only reproducible on our production
(Rails 2.1.1) machine, which sucks as far as trying to track it down.
I'm working on my dev machine in a Rails 2.3.x branch, in which I can
reproduce the problem with a test. Unfortunately, our code is large
and complex, so I can't easily tell if it's something we're doing, or
an issue with Rails, or what.

Here's the test result:
test_get_new(MessagingControllerTest):
NoMethodError: undefined method `content_tag' for "#<Letter:
0x5dc2ddc>":Letter
    app/helpers/our_ui_helper.rb:734:in `our_content_tag'
    app/helpers/our_ui_helper.rb:74:in `content'
    test/functional/messaging_controller_test.rb:122:in `test_get_new'

The failing line of the test is
    assert @reply.content.include?(@original.content), expectation

where @reply is a Letter object, which contains a "content" attribute.
our_ui_helper.rb has a "content" method that's used by templates.

Why in the world would "model.content" ever call a helper method?

Thanks,

is something including your helper module into the model ? (you could
stick some logging in that module's self.included) Does it only happen
with your helper method or also the names of other helpers ?

There was another model that was including ApplicationHelper for some
godforsaken reason. Taking that out fixed the problem.

I'm still unclear why and how this was happening.
