I haven't tried to pass a struct over to a CFC but I have passed an array over
without the need for an extra parameter.
Flex (stripped down):
var formData:Array = new Array();
var obj:Object;
for(var i:int = 0; i< formParams.length; i++)
{
obj = formParams[i] as Object;
if(obj.className == 'TextArea' && (obj as TextArea).editable)
{
formData.push( { name:obj.name,data:(obj as
TextArea).htmlText,dataCheck:(obj as TextArea).text} );
}
else ...
}
report.postForm(formData);
CFC (stripped down):
<cffunction name="postForm" access="remote" returntype="query" output="true">
<cfargument name="formData" type="array">
<cfloop from="1" to="#arrayLen(formData)#" index="i">
<cfif ListLen(formData[i].name,'.') EQ 4 >
<cfset formID = getToken(formData[i].name,1,'.')>
...

and form review
Chris,
I think this might be what you need after thinking a bit more about the issue
you described. Some background info is included (I apologize if it seems
verbose).
I created a test Flex app (it's Flex 4/Flash Builder 4) and a single function
CFC to emulate what you're trying to accomplish. I found (and I remember that
this is something that has existed in Flex/CF since at least Flex 1.5) that
when you try to pass a simple Flex Object as a CF struct (I did not see how you
are actually calling the CFC in your Flex app, but suspect you are trying to
pass a Flex Object as a single entity to CF), you need to apply a bit of 'black
magic' - passing an extra parameter in the remote object call or CF will
complain that the struct is required but was not passed in (Element
FORM_DATA.EMAIL is undefined in ARGUMENTS). Of course you think you're passing
the object to CF, and you are, but "Notice Coldfusion didn?t treat the Flex
object as 1 argument" (according to this link:
http://www.joelconnett.com/flexobjectstocoldfusion.html).
The technique I usually use is shown below (it is just easier to type):
You can pass in a dummy extra parameter like I have in the code below (note the
'' empty string that I pass to the CFC function in line 24:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009";
xmlns:s="library://ns.adobe.com/flex/spark"
creationComplete="appLoaded()"

minHeight="600">

</mx:RemoteObject>
</fx:Declarations>
<fx:Script>
<![CDATA[

import mx.rpc.events.ResultEvent;
import mx.utils.ObjectUtil;
private function appLoaded(): void {
var objUser:Object = new Object();
objUser.email = '[email protected]';
line 24 roTest.recoverPassword(objUser, '');
}
private function
recoverPasswordHandler(eventObj:ResultEvent): void {
if (eventObj.result){
Alert.show('Your credentials have been
sent to the email address on file.', 'Password Recovery Confirmation');
} else {
Alert.show('The email address that you supplied
was not found in our records.', 'Email Not Found');
r }
}
private function roFaultHandler(event:FaultEvent): void
{
Alert.show(ObjectUtil.toString(event.fault));
}
]]>
</fx:Script>
</s:Application>
The CFC I used, test.cfc is shown below (* NOTE: you would need to modify the
cfquery section to match your database and cfadmin
datasource)
<cfcomponent output="false">
<!--- Password Retrieval --->
<cffunction name="recoverPassword" access="remote"
returntype="boolean">
<cfargument name="form_data" type="struct">
<cfset var accountCheck="">
<cftry>
<cfquery datasource="your_datasource"
name="accountCheck">
SELECT clientEmail, clientName, tmppassword
FROM
sometable
WHERE clientEmail =
'#arguments.form_data.email#'
</cfquery>
<cfif accountCheck.recordcount>
<cfmail from="[email protected]"
to="#accountCheck.clientEmail#"
subject="Credentials Request" type="html">
Dear #accountCheck.clientName#, <br /><br />
You have requested that we send your login
credentials for the system on #DateFormat(now(), 'MMMM DD, YYYY')#.
<br /><br />
Your log-in information:<br />
<b>Email address:</b>
#accountCheck.clientEmail#<br />
<b>Password:</b>
#accountCheck.tmppassword# <br /><br />
If you did not request your login credentials,
please contact us immediately at
<a
href="mailto:[email protected]";>[email protected]</a>:<br /><br />
<span style="color:red; font-weight:bold;
font-style:italic;">Please do not reply to this email</span>
</cfmail>
<cfreturn true/>
<cfelse>
<cfreturn false/>
</cfif>
<cfcatch>
<cfsavecontent variable="contentSaver">
<cfdump var="#cfcatch#">
</cfsavecontent>
<cffile action="write" file="#ExpandPath('.')#\debug.html"
output="#contentSaver#">
<cfreturn false/>
</cfcatch>
</cftry>
</cffunction>
</cfcomponent>
Of note, I tried the
"http://www.joelconnett.com/flexobjectstocoldfusion.html link" technique three
too, and that also worked for me.
private function appLoaded(): void {
var objUser:Object = new Object();
objUser.email = '[email protected]';
var objWrapper:Object = new Object();
objWrapper = {form_data : objUser};
roTest.recoverPassword(objWrapper);
}

Mike
