Mapping from string to boolean is non-intuitive. Boolean("false") is
true. Boolean("") is false. See the ASDoc's on Boolean.

Subject: [flexcoders] Flex always returns true, how is this possible?
Hi guys,
I have this very strange problem: here's my code for those that are
willing to help:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml
<http://www.adobe.com/2006/mxml> " layout="absolute">
<mx:Script>
<![CDATA[
import mx.rpc.events.ResultEvent;
import mx.controls.Alert;
private function submitForm():void {
var params:Object = new Object();
params.firstName = firstName.text;
params.lastName = lastName.text;
myService.insertArtist(params);
}
private function myResultHandler(event:ResultEvent):void {
if (Boolean(event.result) == true) {
Alert.show("New Artist added!!");
} else {
Alert.show("Error");
}
}
]]>
</mx:Script>
<mx:RemoteObject id="myService" destination="ColdFusion" source="
RemoteObject.cfc.queries"
result="myResultHandler(event)" showBusyCursor="true" />
<mx:Form>
<mx:FormItem>
<mx:Label text="First Name" />
<mx:TextInput id="firstName" />
</mx:FormItem>
<mx:FormItem>
<mx:Label text="Last Name" />
<mx:TextInput id="lastName" />
</mx:FormItem>
<mx:FormItem>
<mx:Button label="Submit" click="submitForm();" />
</mx:FormItem>
</mx:Form>
</mx:Application>
and my simple CFC contains....
<cffunction name="insertArtist" access="remote" returntype="boolean">
<cfargument name="firstName" type="string">
<cfargument name="lastName" type="string">
<cfset success = true>
<cftry>
<cfquery name="qInsertArtist" datasource="flexdata">
insert into tbl_test (firstName,lastName)
values ('#arguments.firstName#','#arguments.lastName#')
</cfquery>
<cfcatch type="database">
<cfset success = false>
</cfcatch>
</cftry>
<cfreturn success>
</cffunction>
Notice that even if I enter to the end of my cffunction the <cfreturn
false>, my myResultHandler always returns a "New Artist Added" (meaning
that it always report true). The tbl_test table does not even exist!!!
How is it possible to get a 'True' message from Flex? is that kind of a
bug? Or am I doing something wrong? I used to have a similar problem
when using an HTTPService.
Thanks for your help, really helpful :)
George
