ApplicationHelper not available to views and models?

Everything I have read so far, states that the functions in the
"ApplicationHelper" module are available to all views in the
application. I guess they get loaded into the specific controller
automagically and public methods become "protected".

So, I put a function in there, and lo and behold my view cannot see it.
Grrrr.

However, if I put the function in the helper module specific to the
view, voila, it works. This must be the "rails" magic.

So, is something is wrong, or have I not read something important?
Is there a configuration variable for this?

I'm using Rails 2.1.0.

I don’t think there is any configuration variable for this.
Any method declared in ApplicationHelper module should be available to all views until and unless you have done something wrong somewhere.
