Re: [flexcoders] Flex / Flash / FlashComm, Remoting and CF
Yes... I find that is always a good idea to have a cfm page that queries your cfc exactly in the same manner as the remoteobject tag in your flex app would. And use cfdump on your cfm page to examine what the cfc returns. That way you know exactly what is being returned. And if you are using structures and queries, be careful of the capitalization of structure keys and query column names. Trust me, it saves a lot of time.

If not, here's the problem I'm having which I think that ink will solve (Off Topic): I have an FCS app which hits a CF7 server's flash gateway looking for a service. The services which return strings work just fine but anything that returns something more complex doesn't seem to work. I try return.VAR, return.var, return.Var, etc. but it comes back undefined.

Re: [flexcoders] CFlogin, SetCredentials and the RemoteObject
Have you looked at creating named remoteobjects? That way even though
the methods might be visible in the decompiler, but path to the actual
cfc won't be.
Hmm... regarding your swf file finally being part of cfm page... I've
find myself more comfortable with standalone flex apps (that
interact with CF through remoteobject) rather and flex apps embedded
in cfm pages. I find debugging quite painful when a flex app is embbed
in a cfm page.

I was debating if I should have my login page exist within HTML or as a

I mention it because I'm pretty sure the CFC method names and service names
would be visible to a decompiler and thus, visible to any user who stumbles
across the Flex Admin system or has just simple access to the Login screen,
if the login is part of the overall Admin SWF.
Ultimately, my MXML will be a CFM page and I was going to only show the
Flex SWF if the session is valid, otherwise, kick them back to the sep.
login page.
Any thoughts?

Hi Dave:
Here is my setup, I don't know if this helps.
I have a CF application where users need to login. Once they
successfully plug in their username and password, their session is
setup (I'm using jessionid). I have a cfc (with relevant functions for
login/logout) that is used for authenticating users and setting up
session.
I call that cfc as remoteobject, firing the login function in the cfc,
passing it the username and password. If the login is successful, the
session for the user is setup and all is sweet. I can access the
user's session info through the same cfc (i have a function that
returns their session structure Flex. And my Flex code can then look
at the session object of the user and do what it needs to.
I think the key for you would be to get jsessionid going, along with
using functions within a cfc to validate the user and return user's
session (or any other value that you want to return to flex).

Re: [flexcoders] Web Services and CF7
Hi Ted:
I agree with Andrew totally. Using remoteobject to invoke the cfc on
the server is a much more efficient. I've been using remoteobject to
access cfc and it works beautifully.
A question for you: Are you going to be running cf7 and flex on the
same jrun instance?
If you are, keep in mind the following:
1. Remove the flash remoting gateway that is installed by default with
cf7 (through jrun admin).
2. Make sure that in the flex-config.xml, you have the following value
setup for the amf-gateway (under remote-object node).
amf-gateway{context.root}/amfgateway/amf-gateway
3. When calling the remote object (cfc), make sure to add the correct
endpoint (in the example code below). So, for example, if you were
going to call a cfc called foo with the path myfolder/folder/foo.cfc,
you'd use the following call:
mx:RemoteObject id=myService source=myfolder.folder.foo
endpoint=@ContextRoot()/flashservices/gateway
/mx:RemoteObject
Hope this helps.

Re: [flexcoders] Web Services and CF7
Ted, I just found another reason why I'd prefer remoteobject over webservices.
If a cfc extends another component, you cannot access the inherited
functions when using webservices. You will have specifically write
functions in the cfc you are calling to expsore the inherited
functions.
However, when you use remoteobject to access a cfc, you can access
inherited functions without needing to expose them..

Re: [flexcoders] XML vs Model?
Performance-wise I find that both to be equivalent. But mx:Model provides a much easier way to access nodes of an xml document (and most of the times, the easier, the better!). But I agree with Matt's observation that mx:XML serves a better dataProvider for the Tree control.
