Flex :: IsEmpty Error When Calling Parameterless WCF Method?
Apr 12, 2010
I have a WCF web service (using basicHTTPBinding) which I am connecting to from a Flex application. I am using the FlexBuilder code generation to make a proxy for the web service.This has been working great until I tried to call a method on the web service that has no parameters. Here is it's interface declaration:
[OperationContract]
DateTime GetCurrentDateTime();
I then started getting HTTP 500 code responses from the service.Inspecting the HTTP response with Fiddler shows that WCF is reporting the following error:
Error in deserializing body of request message for operation 'GetCurrentDateTime'.
The OperationFormatter could not deserialize any information from the Message because the Message is empty (IsEmpty = true)
So it seems that there is an incompatability between Flex and WCF whan calling methods that have no paramaters - Flex doesn't include anything in the message but WCF is expecting something to be there.Is there any way to configure either Flex or WCF to work around this or am I going to have to include dummy parameters in such operation contracts?

I am trying to emulate (in a limited way) the behavior of JavaScript's XMLHttpRequest object through Flash/ActionScript 3, in order to overcome the same-domain limitation. But I'm discovering that ActionScript has its own limitations in that regard. I admit that I might be mistaken, but from what I understand it is theoretically still possible to do this sort of cross-domain scripting using ActionScript, so long as you get all the permissions right. And that's where I'm running into trouble.
First, I borrowed some open-source code for a class called AjaxRequest, which I have saved as /ajax/AjaxRequest.as. I then created a Flash file called /jsajax.fla which exports to the final SWF file, /jsajax.swf. Now, here's the ActionScript code that comprises the first and only frame of the Flash file:
import ajax.AjaxRequest;
Security.allowDomain("domainone.com");
Security.allowDomain("domaintwo.com");[code]....
This is the only case I could not get working, and this is the case I need to get working. The first two were really just test scenarios to see if the script was working at all. When I try to run my jsAjax function here, I wind up with an error that shows up twice in Firebug:
uncaught exception: Error calling method on NPObject! [plugin exception: Error in Actionscript. Use a try/catch block to find error.].
uncaught exception: Error calling method on NPObject! [plugin exception: Error in Actionscript. Use a try/catch block to find error.].

Making a flash video streaming web-app using Actionscript 3's external Api. I am at a very rudimentary phase of the project where we're just experimenting with external interface. Right now i just have a flash object and 3 buttons each to play pause and load a video. The only button that is currently set up to do anything is the load button. My swf and my html file sit on the same file system, and my video files sit on another server with traffic being redirected through a media server.When i press the load button, which should just give it the path of the video file on it's server. Instead it throws an error that reads "Error: Error Calling method on NPObject". [code]I've read in a lot of places that this is an issue with security, but both my swf and html are in the same folder on my local machine. Only the files come from outside, and in any case I think i've set the security settings correctly when i declare my flash player in the object tag, but maybe i'm missing something there.if you can't solve my question directly can someone please explain what "error calling method on NPObject" means? I'm sure its specific to flash-js communications because i've never seen it before and that's what i have gathered from my googling.

I created a new class as DraggableObject in Flash CS5 with the following definition:
package {
import flash.display.MovieClip;
public class DraggableObject extends MovieClip{
public function DraggableObject(){
[Code].....
Before running the code, I had a simple rectangle object converted to a movie clip and exported it to actionscript with the class of 'DraggableObject'. I just had it in library (i. e. no other instance in the stage). What I wanted is to create an instant of it at run-time ( 'draggableObject' ) and have it added to the display list of the stage, throgh its method 'draggableObject.addToStage()'.
And I don't have an idea as to what 'null object' referes to here. Since I created an instance in the line "var draggableObjectraggableObject = new DraggableObject()", it cann not be null....? When I commented out the line 'stage.addChild( this );' in the class definition (line9) it works with the trace statement output.

I've been playing with the visualization API aka dynamic charts and I've found that the example at [URL] does not really work on localhost. That is, Error calling method on NPObject is thrown when a event is clicked (points A and B in the example aforementioned). I suppose that is a security issue on the server end (Google's flash base).Since that jsFiddle code is hosted on a domain, the note at the very bottom of the documentation should not apply:Because of Flash security settings, this (and all Flash-based visualizations) might not work correctly when accessed from a file location in the browser [URL] rather than from a web server URL [URL] .

When I tried to run this code Flex throws an error. It says that loadDetails is not defined. I suppose that error is because of scope.

I am working on a quiz system. Normally it uses jpeg images with each question. But a few of the quizzes instead feature animated .SWF files. I want to use jquery swfobject to call the play() method, once the user has clicked on an answer.
My solution works fine locally, but when I try to run it online, it throws the "Error calling method on NPObject!" message.
The quiz HTML is located on www.somedomain.com and the SWFs are on images.somedomain.com. So, I'm guessing this is a cross-domain thing.
Trouble for me is, I don't know anything about Flash... how to edit SWF files, anything about Flash attributes, or the like.
Here's an example of my code:
<div class="photos">
<object data="http://images.somedomain.com/q1tattooquiz.swf" type="application/x-shockwave-flash" width="600" height="350">
<param name="movie" value="http://images.somedomain.com/q1tattooquiz.swf">

So I have an AS3 audio player which receives commands from Javascript.I have a function in the flash file called 'set_song', which sets the URL for the song to be played. The first time I call it using something like
Code:
document.getElementById('audio_player').set_song(response.url);
(response.url being the URL response from an AJAX call) it works fine and all the other functions on the player work fine but if I then run the same function a second time I get the "Error calling method on NPObject!" error in Firebug. I googled this and it said it was something to do with permissions but;
The site is at dftba[dot]com
The flash file is at dftba[dot]com
The javascript files are at [1/4][dot]cdns[dot]dftba[dot]com
The audio files are at vox[dot]dftba[dot]com
And I have
Code:
Security.allowDomain("dftba[dot]com");
Security.allowDomain("www[dot]dftba[dot]com");
Security.allowDomain("new[dot]dftba[dot]com");

private function init():void
{
ExternalInterface.addCallback( "playVideo", playVideo );
}
[code].....
However if I uncomment and run the alert first. I get no error and it works perfectly.My first thought was that the alert was buying time until the script could execute, so i tried to run the script inside a setTimeout() but did not work.
