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 stillFlex'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.

RE: [flexcoders] Calls to CFCs
Are you setting remote-objects-debug in flex-config.xml?
What version of ColdFusion are you using?
Re: the unsupported type in stream message... are you doing
anything like the following:
var s:String = new String("foo");
var b:Boolean =
new Boolean(true);
var n:Number = new
Number(4);
Unfortunately in AS1/AS2 the Flash Player does not
recognize the Object form of String, Boolean or Number type for serialization
purposes so it sends them (yes, oddly) as an unsupported type when serialized as
AMF which the remoting gateway rejects. If you use the "primitive" forms of
these types in ActionScript:
var s:String = "foo";
var b:Boolean =
true;
var n:Number = 4;
It should work
fine.
Out of curiosity, how
are you generating the data that is sent to the CFC? Are you loading a web
service first by any chance and then trying to send that result to a CFC via
remote object?
Can you post the
cffunction and accompanying cfargument tags from your CFC method
that you're invoking? Can you also post the ActionScript line you're using to
call the RemoteObject abstraction of your CFC?

RE: [flexcoders] Calls to CFCs
I could probably solve your JRun errors too if you posted
them... but that aside, I can help you turn on server side tracing for the CFMX
7 version of the gateway what you need to do is look out for the
gateway-config.xml file that is specific to the gateway that you're calling. It
might be under:
/WEB-INF/coldfusion/gateway-config.xml
I believe the servlet that's mapped to /flashservices will
have an init param in /WEB-INF/web.xml that points you to the location of the
configuration file that the gateway is using.
Anyway, in this file you'd set the logger to
debug:
logger level="Debug"(whatever gateway
logger implementation CF uses would be listed here... I think it was
coldfusion.flash.ColdFusionLogger if I remember
correctly)/logger
You should then be able to look at the log to see a dump of
the AMF traffic that went through the gateway's serializer... this might give
you a clue as to which parameters are being sent to your CFC
method.
I think CFMX 7 redirects log info to a flash.log. If you
started JRun from the command line and wanted to just see this info on the
console you could always switch to use the DefaultLogger:
logger
level="Error"flashgateway.log.DefaultLogger/logger
Also, I'd still like to look at the cffunction and
cfargument tag signatures for your CFC method
In any case, can you try this instead:
var otd_tech_after_db:String = "";var otd_tech_before_db:String =
"";
If
it's not that, can you try narrowing down which attribute is causing it in the
call (i.e. by sending null or something you know is a primitive type or a
structure that could not possibly contain non-primitive types for the
aforementioned Boolean, String or Class types... i.e. don't necessarily trust an
API to return you a primitive until you've tracked down the
cause)?

Re: [flexcoders] Calls to CFCs
Here is the start of the CFC function
cffunction name="get_tech_search" access="remote"
returntype="array"
cfargument name="before" type="string"
cfargument name="after" type="string"
cfargument name="innovators" type="array"
I tried the change on the variables and nothing.
I then replaced the variables I was sending with '' and in the cfc made
innovators a string vs array and still got the error message.

Unfortunately in AS1/AS2 the
Flash Player does not recognize the Object form of String, Boolean or
Number type for serialization purposes so it sends them (yes, oddly) as
an unsupported type when serialized as AMF which the remoting gateway
rejects. If you use the "primitive" forms of these types in
ActionScript:
var s:String = "foo";
var
b:Boolean = true;

I could probably solve your JRun errors too if you

for the CFMX 7 version of the gateway what you need to do is look out
for the gateway-config.xml file that is specific to the gateway that you're
calling. It might be under:
/WEB-INF/coldfusion/gateway-config.xml
I believe the servlet that's mapped to /flashservices
will have an init param in /WEB-INF/web.xml that points you to the location
of the configuration file that the gateway is using.
Anyway, in this file you'd set the logger to
debug:
logger level="Debug"(whatever gateway
logger implementation CF uses would be listed here... I think it was
coldfusion.flash.ColdFusionLogger if I remember
correctly)/logger
You should then be able to look at the log to see a
dump of the AMF traffic that went through the gateway's serializer... this
might give you a clue as to which parameters are being sent to your CFC
method.
I think CFMX 7 redirects log info to a flash.log. If
you started JRun from the command line and wanted to just see this info on
the console you could always switch to use the
DefaultLogger:
logger
level="Error"flashgateway.log.DefaultLogger/logger
Also, I'd still like to look at the cffunction
and cfargument tag signatures for your CFC
method
In any case, can you try this
instead:
var otd_tech_after_db:String = "";var
otd_tech_before_db:String = "";
If
it's not that, can you try narrowing down which attribute is causing it in
the call (i.e. by sending null or something you know is a primitive type or
a structure that could not possibly contain non-primitive types for the
aforementioned Boolean, String or Class types... i.e. don't necessarily
trust an API to return you a primitive until you've tracked down the
cause)?

Re: [flexcoders] Calls to CFCs
There are a couple of ways I have used to debug calls to CFCs... Create a CFM template and call the methods on the CFC the same way you want your Flex app to. This will let you know if it is the CFC having a problem. When you call the method, dump out and write the dump to file using cfsavecontent This way you can see what CF is getting from the Flex app. May be usefull to see your calling Flex code to give us an idea of how you are calling the cfc. On 9/28/05, Greg Johnson [EMAIL PROTECTED] wrote: We are currently running the dev/demo copy of flex to see if it will do what we need. Thing is we have ran into a strange bug. The code makes a call to a CFC and gets back data fine the first time, but the second time we make a call it just gets hung up. Yet I don't run into the problem when I am on the server itself.

RE: [flexcoders] Calls to CFCs
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 ;. http://cfxtest.research.unc.edu/flashservices/gateway/;jessionid=XYZ123A BC 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?; Pete -Original Message- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Muzak Sent: Wednesday, September 28, 2005 11:22 AM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Calls to CFCs 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.

Re: [flexcoders] Calls to CFCs
Did you test every thing from the CFC side of things to?
Making sure the CFC is getting the correct arguments?
I would put some code like this at the beginning of your function in the CFC...
{all cfarguments and vared variables here}
cfset var myArgs =
cfsavecontent variable=myArgs
cfdump var=arguments
/cfsavecontent
cffile action=write file=c:\flexTest_#getTickCount#.html output=#myArgs#
{rest of function here}
This will let you know if the function is being called the same way
both times
Your code looks OK at first look BTW.
I am presuming the CFFunction is returning a Query?
A way to see what you get back is
in the doResultGetTechEvents function
for(var i in result){
trace(i = + i);
for(var o in result[i]){
trace(o = + o + :: result[i][o] = + result[i][o]);
}
}
About now I can hear the question I asked when I first started with
flex (about 4 months ago...) How do you see the trace statement
results?
You can down load a version of flashplayer that writes the traces to a
file called flashlog.txt
The MM site has instructions on this...
you can then see what the Flex app is getting back...
