RE: [flexcoders] Calls to CFCs

Note that my suggestion was to append the ? query string marker, please let me know if this resolves the issue as your initial symptoms described the issue with AppendToGatewayUrl exactly.
 
Also, the problem is that Flash Remoting (and hence still Flex's RemoteObject) with ColdFusion introduced the concept of named arguments. That is, if your CFC is expecting a Struct as a single argument and you're sending it an object, then it won't work as the CFC proxy between the gateway interprets them as "named arguments" and thus looks for parameters to match each of the keys in the AS Object. Try adding a second, dummy variable to the CFC function and let me know if this solves the issue.

I will give that the / suggestion a try.  As a workaround I switched to a webservice vs remoteobject and it has no problems and seems to let the client load faster.

But I just commented out the remoteobject so I will try flipping back and see what happens.

Now my biggest problems are I am making a call to a CFC and passing it a parameter but the CFC is complaining that it wasn't passed.  Plus my debugger for some reason who let me watch variables anymore.  I put an alert in the Flex code just before the CFC call and it shows valid data in the variable I am sending, but it just doesn't get to the CFC for some reason.  Doing the same exact thing with all the other CFCs and they work fine :/

Actually, it's likely that you're getting an AppendToGatewayUrl AMF
Response Header from the server because it detected that while a session
was created during the request, the client didn't inform the server
whether it could accept cookies.

This AMF Response Header is trying to tell the client NetConnection to
decorate its connection URL with some extra info, for example a
jsessionid for Java or a cfid/cftoken for ColdFusion.

You may then be using IIS... In which case it may be barfing on the
semi-colon in something like the jsessionid token, irrespective of
whether you have a ;.

I believe CF released a hot fix for this issue, but the work around is
easy... Just add a ? To the gateway URL (or "endpoint" in flex speak) so
that the session information won't annoy IIS.

endpoint="http://cfxtest.research.unc.edu/flashservices/gateway?"

A wild guess: try adding a "/" at the end of the gateway url.

endpoint="http://cfxtest.research.unc.edu/flashservices/gateway/"

I've seen USERID and alike being added to the gateway url when making
remote calls.
In that case, without the ending '/', the gateway url gets messed up.

Might not be the case here, but it's the first thing I'd check ;-)
