Parameter not passed in error

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 to 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 then 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.

BKBK,
That is part of my thrashing about, trying to either make it
work or get a real error message. I changed the Flex and .cfc to
pass the previously missing parameter to the descriptionUpdate
function. If I pass the newENGRemark variable to the first update
function, everything is fine; if I pass it to the second update
function, it is missing.
I changed the Flex and .cfc be all upper case and all lower
case, but there was no difference.
I created a .cfm page to cfinvoke the same .cfc; then I
passed some hardwired literals to the .cfc - everything was fine.
I put the Flex code back to only pass two parameter to each
update function, but in the .cfc, in the second update, I added the
default option to both of the parameters. That worked; it went
ahead and updated the record with the defaults. (That's not really
what I wanted to do for production) . I changed the .cfc so the
newENGRemark was not required. Then it said the second parameter
was missing. In the Flex code, you can see that I am passing a
litteral, 925001, to the .cfc. The parameter exists in Flex, but
when it gets to the .cfc, it doesn't exist.
This problem has been beating me for too long. I think I
will restructure the database so that I can do what I need to with
one update function call. The initial test seems to show this will
work.
Basically I am floored by this problem. Everything I've
tried to get around it or get a real error hasn't worked. Could it
be something to do with Oracle CLOB data type? Because I was able
to make it work by using a .cfm to cfinvoke the .cfc, it seems that
the problem would have to be in Flex. But the Flex only seems to
have a problem with the second update, UpdateEng. So I deleted the
second update, copied the first, and changed the the minimum to
make it work, but it didn't. Then I switched the order in the Flex
and .cfc to have the second update first - same difference. Then I
even took out the descriptionUpdate altogether, but it still gave
that same error.
Does anyone know of some diagnostic tool that can catch what
is being passed on the AMF channel? Can you do a dump or a debug of
a .cfc that is called by Flex?
