Cfc error when using Flex and RemoteObject (cross post)

Question

I have Flex 3.0.214193 and CF 8,0,0,176276 and Oracle
10.2.0.3.
I've been search for several days for an answer to this one.
There is very little out there about this type of error, but then
there is very little about any problems with Flex and ColdFusion.
In Flex, I have two comment fields. the .cfc has two update
functions that update the comments, because they are in two
different tables. The first update works like a champ. The second
one consistantly shows this error in the CF application log: The
NEWENGREMARK parameter to the updateEng function is required but
was not passed in. I've used the Alert.Show to verify that Flex
does have a value in that variable when it calls the .cfc. I've
even tried passing the first variable that worked in the first
update, and even a litteral value. Everything yields the same
cryptic error message. I must be looking at the wrong thing.
The only things I've found on the web about this, say the
variables should have a scope (is that a scope in Flex or in the
.cfc) and the column names should be in upper case (because it's
Oracle).
Here's the .cfc code (is that where the error is, or is it in
Flex?). The UpdateDescription function works, but the UpdateEng
doesn't.
Thanks for any help, or spelling errors you can point out.

Ian,
I also heard about the case thing. So I tried everything in
upper case and lower case - same thing. In my experimenting, I
tried adding the newENGRemark parameter to the descriptionUpdate
function call, I didn't do anything with it is the .cfc just
declared it as required. In that case the parameter exists and
everything is fine. But in the call to the UpdateEng, it doesn't
exist.
I changed the .cfc so that the newENGRemark was not required
or had a default. In both cases the .cfc just skipped to the next
parameter and said it didn't exist. But I was passing a litteral,
it wasn't even a variable.
I created a .cfm page that did a cfinvoke on the .cfc, and
passed it two litterals. That worked fine. So that makes it look
like some sort of syntax error in the Flex. So I deleted the call
to the UpdateENG, copied the UpdateDescription call (because it
works), changed just the minimum to make it work, but it didn't
work.
I think I am going to restructure the database so that I can
do what I need to with just one update function, that seems to
work.
It still doesn't make any sense.
