Flex :: Testing - Null Object Reference With Automation Enabled Flex-application At Preloader?
Jun 10, 2010
We are trying to automate our flex application. After adding automation libraries to our project we get the following exception:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.automation::AutomationManager$/addDelegates()

We are using Flex 3.4 and maven2 to build the application.

which tool should i use QTP, RIATest , Selenium for Flex Application Functional Automation Testing. please help me compare them with different advantages and disadvantages.
We have a flex based UI whose functionality (eg: login, logout) needs to be tested periodically in IE 7. Manual testing takes a lot of time and hence we want to automate it EDIT: We dont have the source code of this app uder test so cannot use something like FlexUnit. Is there a way to automate this testing?
I have heard of FleXmonkey, but have read negative reviews of it and hence wary of trying it.
Here is the error:TypeError: Error #1009: Cannot access a property or method of a null object reference.at mx.styles:: StyleProtoChain$/ initProtoChainForUIComponentStyleName()[C:autobuild3.2.0frameworksprojectsframeworksrcmxstylesStyleProtoChain.as:72][code]......
Maybe you could school me in how to keep null object references out of complex Classes?
I have function init, which runs on the creationComplete of the application. The init calls get_login_share_object funtion, in which objects are created, which are null.
Now my problem is that, I get a null object reference error on the Alert in "init()". How can I avoid that. Is it possible that I can have a check to see, if the objects are null the program should just skip reading the objects.
private function init():void { var stored_credentials:Object = get_login_share_object();
I am a novice in Facebook developer by choosing ActionScript 3 as my developer platform. I use SWC library from official facebook-actionscript-api that promoted by Adobe.So I followed their tutorial.[code]
I try to do preloder in Flex for my project written in Flash. I make this with the help of this site link text My Flash project have next source in main class called Game
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown); stage.addEventListener(KeyboardEvent.KEY_UP, keyUp); private function keyDown(event:KeyboardEvent) {
[Code]....
Flex application work but Flash application does not react to button presses
how I can make preloader and work buttons together
TypeError: Error #1009: Cannot access a property or method of a null object reference have a mxml file that has actionscript inside of it, I'm trying to call a function in a button outside of this actionscript in the same mxml file. I'm calling the public function cancel(); like this click="cancel();" but i'm getting an error 1009 that I can't access a property or method of a null object reference
Simple to understand problem, hoping for similarly easy solution:When I type in my search query, I sometimes get the "Error #1009 Cannot access a property or method of a null object reference" on the dataField = new ArrayCollection(result.data); line.
I'm using code for the open source MP3 player Howler and trying to port it to a Spark MobileApplication type. I'm getting a null pointer exception and I have no idea what's causing it. I've tried debugging extensively with breakpoints at what I think is causing the error, and set breakpoints in the untouched Howler project but all the variables in scope seem to be identical between my non-working project, and the Howler project. The only thing I can think of is that Howler uses MX components and I am using spark. I've pasted all my code below (which is very long) but I've bolded the lines that are throwing the error. The error occurs immediately after I choose a folder in the browse folder dialog.
I have a flex application which use DragManager.When I'm loading this application into flash application and trying to use drag'n'drop functions - I get an error:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at mx.managers::CursorManagerImpl/showCurrentCursor() at mx.managers::CursorManagerImpl/setCursor() at mx.managers.dragClasses::DragProxy/showFeedback() at mx.managers.dragClasses::DragProxy/mouseMoveHandler()
But, when I simply run a flex application (not loding it into a flash one) everything works properly.
I am having really annoying problems with Flash. I am using CS4 and the file uses AS 3.0. Anyway, on to the problem. Basically I am creating a flash-only website. Source code for main site:

After I have done this, the whole thing is not working anymore, and I get the following errors: TypeError: Error #1009: Cannot access a property or method of a null object reference. at website_fla::MainTimeline/frame2()[website_fla.MainTimeline::frame2:3] at flash.display::MovieClip/nextFrame()
I have called this flash code in Flex using SWF loader . I got the following Error. Here I have attached flash coding for header_text_fla Kindly do the needful.
TypeError: Error #1009: Cannot access a property or method of a null object reference. at header_text_fla::MainTimeline/loaderComplete() var myEvent:Event; var myParams:LoaderInfo;
My preloader keeps displaying an error when I try and load my SWF in it.
TypeError: Error #1009: Cannot access a property or method of a null object reference. at Main()
The swf works fine but the loader doesn't work with it. I worked out that it was because I used "stage" in the eventlisteners of the SWF file but if I remove these the game keys don't work, but the loader does.
I have a preloader which has this code (simplified):
Code: Select allvar loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaded); loader.load(new URLRequest("x.swf")) function loaded(e:Event):void {}
And x.swf has this code (very simplified): Code: Select alltrace(stage.stageWidth); When I run preloader, I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at x_fla::MainTimeline/frame1()
how to change different section with as3 and custom document class, everything run fine , but when i try to use the preloader tutorial that load the swf file , i run to some error it said " TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Main/init() at Main()"
Main is the name of my custom document class, and here is my document class code
I just found the external preloader tutorial and it's Perfect, exactly what I needed! I just have one issue which I can't figure out.. It all works fine with other swf files such as the content.swf example it comes with, however when I try link it to a site I'm making (a fluid as3 layout) it states: "TypeError: Error #1009: Cannot access a property or method of a null object reference. at Website()" Here is the syntax - it's just the same as on the tut but trying to load 'website.swf'..
I am quite confident i am having no issue with my preloader codes and have managed to identify why i keep getting the Error #1009: Cannot access a property or method of a null object reference. My preloader.swf is loading a home.swf. Within this home.swf i have some codes that makes reference to the stage. EG stage.stageWidth/2 Once i deleted away this line of code there is no error. Is there anyway that i can still reference my stage in home.swf without getting Error #1009?
In my flex application I have several pop ups, when a pop up is opened the application is disabled and enabled back when the pop up is closed.Is there way to get application's enabled / disabled event and perform some activity like hiding a display object.I know, I can get open and close event of the pop up but I don't want to write it for all the pop ups and pay for maintainability.
How do I embedded a HTML-enabled javascript editor on top of Flex web application? FCKEditor is not free but any free editor with basic toolbar will do?
I'm new to flex and actionscript. I'm trying to create a small flex app that has multiple states, but if I have nested containers, it looks like some of the objects are not getting initialized when I expected them to be, even when I have the creationPolicy set to "all."I've reduced the issue to a small example, with a commented block showing when it does work.sing the existing code, I get this error: "TypeError: Error #1009: Cannot access a property or method of a null object reference at main/init()" and the event handlers are not installed.If I instead use the commented block, which has the Panel and VBox elements removed, it does work.I know I could add a click attribute to the mxml elements, but this is just a simplified example, and I'm more interested knowing why the objects are not initialized when the app loads.
I run my code, it will give me a "Cannot access a property or method of a null object reference" error. I double checked, I realized when the program run until the component file up to the accessing dataGridData variable, that dataGridData variable is null at that time. That is probably flex initiate the component file before it send or get the xml data from server in main. Which cause the variable is still null at the mean time.
I'm getting 1009 errors on the second line. I've been looking at this for a while and can't figure out what it can't find. The OnAssetsLoaded function is there.
I use this pattern to test for undefined and null values in ActionScript/Flex :
if(obj) { execute() }
Unfortunately, a ReferenceError is always thrown when I use the pattern to test for child objects :
if(obj.child) { execute() }
ReferenceError: Error #1069: Property child not found on obj and there is no default value.Why does testing for child objects with if statements throw a ReferenceError?
