Wcf :: Flex - Unable To Find Definition For Type From WCF Service
Nov 9, 2011
I have a WCF Service running SOAP and allowing Flex / Flash to connect to it using basicHttpBinding by using the 'Data' 'Import Web Service' option. Unfortunately when I consume and invoke this service within Flex it throws the following error...
Error: Cannot find definition for type
'http://schemas.datacontract.org/2004/07/System.Drawing::Size' at
mx.rpc.xml::XMLDecoder/decodeType()
...when using the following code...
// This will return an array of presentations
var service:PresentationAuthoring = new PresentationAuthoring();
var token:AsyncToken = service.getAllPresentationByClientId(
[code]. ..
This method returns an array of Presentation objects that are retreived by the service. At the moment there are no DataContracts and I'm allowing the POCO Presentation object to be serialised and punted out by the service that works fine. However, this class has a readonly property of the type System.Drawing.Size that derived from appropriate height and width properties. Looking through the generated code, it doesn't register a 'Size' class in the base import schema although it still seems to create a Size class.
An alternative has been to stop the derived property from being serialised using the [XmlIgnore] but that has not worked. I need a way of allowing my Flex application to communicate with my WCF service but it seems to choke on the System.Drawing.Size type and while I could change this, there are other framework types such as Point, Rectangle, etc, etc. that are utilised within the project.

I would like to use different service definitions in a Flex app depending on whether I'm running on:
My local developer machine
The test tier
The QA tier
The production tier
My services are all AMFPHP remote objects, living on different hosts and at different locations depending on which tier I'm on. How can I have my flex app choose the 'correct' tier at runtime to connect to?

This is the response to my question/error I get, but I don't know how to implement it, It turns out that my issues were caused by having two instances of the same data service class in two different components that were used in the same page. If I changed the components to share the same instance of the data service, then everything works just fine. how to define a service in the main application or elsewhere which can be shared between components?

I can identify the type of an object in flex? In particular I have an array where I store multiple types in (but all UIComponents) now as I evaluate the array I want to find out whether I have a TextInput Control or a RadioButton. Does someone have an idea?

I'm running asdocs from a .bat file with flex sdk 3.2.0 (I have replaced my long project root folder with PROJECTROOT):"C:Program Files (x86)AdobeFlex Builder 3sdks3.2.0inasdoc" -source-path . "C:Program Files (x86)AdobeFlex Builder 3sdks3.2.0" "_PROJECTROOT_Componentssrc" "C:\_PROJECTROOT_assets" -doc-sources .PAUSE"Unforunately, I keep getting errors similar to this:"_PROJECTROOT_assetsstyles.css(344): Error: Invalid Embed directive in stylesheet - can't resolve source 'Embed(source = "close_button.png")'.downSkin: Embed(source="close_button.png");"I really don't understand this as "close_button.png" is in the same folder as styles.css. When I build the project from within flexbuilder, it compiles it fine and does not throw any errors.

I'm trying to connect to a very simple .NET WCF web service (created in .NET 4.0) within Flash Builder Burrito and the process hangs on "Introspecting the service". I get no errors -- it just hangs. The web service is on my local network, although not on my local machine.

About 1,5 years ago, met with a Web site. On the website you can upload multiple pictures of the object taken from different sides, and the site gave me a flash movie with my object but in 3D. Very similar to what it is now showing photos in Google maps.
Tell me where I can find a similar service or a script?

I am experiencing a strange problem when I want to bind a service to a button or something else:
[Code]...
I can add the services to the Data Services panel but I have two strange things:
1) when I want to configure the return type he doesn't let me create a new ValueObject type, I only get the bottom datagrid which states: Properties returned by the operation: Property: country_Id, provence_Id, city_Id, id_cdpc, district_Id with the related values on the right side. Why can't I create a new data type on the top?
2) When I accept this and want to add the service call to a button (drag&drop) I get the following error: Error occurred while generating code. Make sure that there are no compiler eroors and try again after reopening the file. Componentn type services.cdpc.CDPC not found... (ps: When I perform a Test Operation everything seems to be ok, I get the expected output values)

is it possible in as3 to override a variable defined in a super class simply redefining a variable that has been defined in super class creates this error
ActionScript Code:
1152: A conflict exists with inherited definition classA.Type in namespace public.
i know i could use get/set methods or pass class type through constructor but thats not an elegant way to do what im trying to do.

I have a site that plays either .mp3 or .flv files depending on what is selected from the menu. Menu loads in from xml. I get "unable to make connection with server or unable to find flv on server" when I try to play the video. But the video and audio files are all in the same directory and the mp3 files play fine. I think I'm having a problem with the setMedia command. Here's the code that loads the video and audio files.

I have a App.fla file on a path and a App.as file on the same path. On the Class field I put "App" and on the ActionScript Settings Source path there is "." which means the same path of the .fla file, right? I open the App.fla file and click on the little "pencil" icon in order to edit App.as but then Flash whether tells me there's no class file associated or it opens a new ActionScript file.
So I can't do nothing , I even copied all code into the App.as , and pasted into the new ActionScript file it generates when I click the little pencil button. It still cannot find the god damned class. A little detail, I'm using Mac OS X 10.6.2. I've been working full time with flash on a Windows and that never happened to me before. That hasn't happend to me on Mac either (though I have hardly used it to do FLASH/AS).

A seperate movieclip named page4 shows in the library to have 6 uses. On the clip are two text boxes both static and one has a movieclip button overlayed. Selecting any of the three changes the propery panel for allowing editing. However. Even though I can see the reference point (the cross) of the movieclip page4, I can find no way to get flash (CS5) to show me the properties to allow giving it an instance.

This should be rather simple, but for some reason i'm only able to find methods to just diplay a random image, but i want the image to change once a day not every time you load the page.
All i have atm are a empty movieclip to load the photos, an upload system in flash that uploads photos to a specified directory, but now i have to figure out the AS to make the movieclip load a random photo from a specified directory once a day.

I'm having an issue with Movieclips inside my Swf resizing to the wrong dimensions. I'm currently tracing the width of the offending clip every half second, and I can see the value change to an incorrect size at some interval in the logged output. I really want to see what code is changing the width. My plan was to extend Movieclip, override the set width property, and dump a stack trace when the value set is too low. This isn't so simple however. Flash is complaining about undefined reference to UI components that are on the Movieclip fla. Is there a simple way to find out when/why this value changes? I cannot use a debugger.
edit: The reason I cannot just extend MovieClip is because I am getting my Movieclip object from Event.currentTarget.content after using a Loader. I cannot point my Test (extends MovieClip) object at this return value because it is illegal to do so.I have an app with lots of different windows. They all open to a size of around 750x570. One of these windows contains a FusionChart. when I load this, according to my trace, the background Swf I am using changes to a dimension of about 2712x1930. This doesn't make sense to me because it looks the same size as before and at those dimensions it wouldn't even come close to fitting on my screen.If I then close the window and open another, the new window is tiny, but says it has the same dimensions as the original windows (750x570).
It is almost as if the window is scaling to the huge 2712x1930 without showing a change in size, and then showing the next window (750x570) as a size relative to what the huge window would look like. If that makes sense...

I'm trying to iterate through all the objects in the stage and I'm not sure how to do it. It's kind of improvised through my previous experience with C# and javascript. First I need the correct list/array with all the stages children. I need to check their type. I have a special custom class which extends Sprite with some additional properties only.
Someone proficient in actionscript 3.0 who can show the proper way to do?

I need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites). I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g. Suppose that I have a collection of Sprites (a pool, in fact). Each sprite will be added to the stage and perform some action. After that, it will die. I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage. This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System. A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...
Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc... But, this is JUST ONE scenario...
At the moment I'm trying to use a Object Pool with a Linked List... Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.

I have some problems using dynamic textfields, spent hours to get it fixed but nothing works. Here's the problem. I've created dynamic textfields where visitors can enter their data, like name, address, comment and so on. My website appears on fullscreen when the web address' typed in. When it's in this fullscreenmode, I'm not able to type in any data in this textfield. When I leave the fullscreenmode I am able to type in my data. Also I've created a dynamic textfield, which loads this sent data from an external database. Now I want to add a scrollbar to this textfield, so all the messages that doesn't fit in the field will be visible. I've tried to create my own, without success, even the simple one in the componentspanel doesn't work.
