populate: n00b error?

[cf_sarahk]

ARG[KEY] parameter to the set[Key] function was required but not
passed in.

I just started learning FW/1 along with MVC in general and OO in CF.
For trying to do it all at once, I think I'm making pretty good
progress;)

I'm not sure if I'm misunderstanding how populate works, or if I
simply have errors in how I'm referencing my objects. Are the
following two lines of code equivalent (or roughly so)?
<cfset dum2 = app.setAppId(Arguments.rc.appID) />
<cfset variables.fw.populate(app,"appID") />

The first seems to work, while the second throws an error:
ARGAPPID parameter to the setAppID function was required but not
passed in.

Before I started troubleshooting, I actually had the populate line as
<cfset variables.fw.populate(app) />
In that case it seemed to randomly pick a key to throw the error
about. One time I would test it and the error would be about appID and
another time about appTitle or any of the other keys. I did not notice
any pattern to the order in which it threw these errors (and it only
threw one at a time).

Thanks for any help you can give in either helping me understand
populate or in learning where to look to find the error.

The convention assumes that the argument to setFoo() is called foo.
Your setAppID() method should have a single argument named appID.

Perhaps if you could show code and the stack trace, we'd be able to
help you better?

I hate missing obvious stuff!! Your answer must have the words in a
different order than in the docs I've read over and over. I'm not
sure how I went down the wrong path to begin with, but I had the arg
in setFoo() named argFoo rather than foo. And then I guess I'd looked
at it for so long that I couldn't see the difference.

arrggh!!

and THANKS:)
