ActionScript 3.0 :: Null Object Reference - Function "menuClicked()" Not Seem To Work
Jan 12, 2010
I got a small problem with a null object reference The problem is that the function "menuClicked()" not seem to work that good. It works fine if i'm not running it in the cases in the "urlChange()" function. But when i do so i get this error and i just can't see what im doing wrong here. The urls works finw btw. But i need to run that function to get the right content added regarding to the selected menuitem. Someone who knows?

I'm having a hard time because of an "Error #1009:Cannot access a property or method of a null object reference" Iget everytime I try to run my Flash-movie. I've attached the codethat is contained in frame 1.The function bringUpEasyQuestion is defined on frame 2, alongwith other functions that are defined there. Now when I test themovie, I get this message:TypeError: Error #1009: Cannot access a property or method ofa null object reference.at MES_fla::MainTimeline/bringUpEasyQuestion()atMES_fla::MainTimeline/frame1()I've read that the Error1009-message means that you aretrying to access something that isn't there yet. And indeed, thebringUpEasyQuestion-function accesses objects that exist only onframe 2. But the first line of the function bringUpEasyQuestion isgotoAndStop(2);. The curious thing is that it works when i put thelast line of the code in frame one (the function callbringUpEasyQuestion(0);) on the first line
with the command gotoAndStop(2);?

I've read through several threads about this error, but haven't been able to apply it to figure out my situation... My flash file is an approx 5 second animation. Then, the last keyframe of each layer (frame #133) has a button in it. My flash file should stop on this last key frame, and you should be able to click on any of the 6 buttons to navigate to another html page in my website. Here is the Action Script that I have applied to the frame in which the buttons exist (on a separate layer, see screenshot at: [URL]

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 have a custom function that doesn't function correctly the first time the function executes it removes a textFiled from the display list without a problem but the second time that it executes it won't remove a diffrent textfield and I don't know why here is the code from the time the textField is added to the diplay list to where its deleted.Btw the function in question is being executed by a custom event listener.....the errors i receive are TypeError: Error #1009: Cannot access a property or method of a null object reference...Also note that i can remove the textField in question from any function other thatn the one the custom event executes.
PHP Code:
sendBtn.addEventListener(MouseEvent.CLICK, sendMsg0,false,0,true);
msgOut.addEventListener(KeyboardEvent.KEY_DOWN, sendMsg1,false,0,true);
comboBox.addEventListener(Event.CHANGE,chFontSize,false,0,true);[code]..........

i am working on a project that has separate swf files serving as different sections (students, faculty, etc). for each section, on the first frame i have a combobox that lists the different values within that particular section. when a user clicks on the value, it takes them to the specific frame within that swf. there are two problems:
1. when the user selects a value, everything functions correctly but an error is thrown that says:

I have begun on a list: My reference is null!Stage is null! Convert this code from as 2 to as 3 for me! Crossdomain policies are in the way of my cool idea Dynamic property names I need to use stuff on the parent! I don't want my children to scale when I scale the parent! Classes vs instances. Mod note: I do not want this topic pinned, we will use a fresh topic once we have agreed to the content.

I thought I understood this stuff by now; the objects within a function are onlyaccessible within that same function, unless you return it to whatever called the function.However I dont think that you can do that for a function called with an eventlistner, so I set up what I thought was a global variable and set its contents within the function, thinking that the contents would be accessible later:
ActionScript Code:
var bmpd:BitmapData;
var URLReq:URLRequest = new URLRequest("sample.jpg");

On the stage there's an empty clip called mc1in the library there's a clip called with the class name Ballnow every frame this functions is executed:mc1.addChild(new Ball())inside ball, at frame ten:this.parent.removeChild(this)so this creates a bunch of balls on the stage, but after a while this error shows up:TypeError: Error #1009: Cannot access a property or method of a null object reference.t Ball/frame10()Edit: ok by tracing Ball's name I understand that even though the Ball is removed it continues to exist somewhere?

I'm animating some mc's at the beginning of the timeline with AS3 (mostly alpha fades), but then I have some tweened animations further down the timeline and a "naviagation bar" that's on all frames, so a user can click a button and jump to a part of the timeline to see some other animations.My problem is that if I don't wait to see the programmed animations at the beginning and just clicka button to see the other tweened animations, I get an error:
"Error #1009: Cannot access a property or method of a null object reference. at flash_fla::MainTimeline/tube_glow2_animate()"
(tube_glow2_animate() being the name of a function)

My movieclips are being nulled when moving between scenes, they are created on the stage and accessed through as3. I have login screen with three button, one logout, one exits the system and the other takes them to the next scene. When going back to the login scene, and trying to access movieclips like add eventlisterners etc... it comes back with null object reference, claiming that my buttons which are on the stage are null and sure enough if I debug they are. Any reason why my movieclips are being made null when moving between scenes?

I have a movieclip that I add to the stage and Im trying to reference a input text field on the second frame.When I trace the textfield on the first frame via the constructor it returns object textfield correctly.When I hit the enter button to go to the second frame where I will need to use password... I get a null when tracing. I can see it, I can write in it and no matter what I do I cannot seem to reference it.
Code:
public function Registration():void
{
trace(this.usernameField); //returns textfield correctly[code]...
In case you need the parent of registration its just the document class and I create registration like this..
Code:
var registration:Registration = new Registration();
addChild(registration); //ive also added it to the stage w/ no luck

I have a form where a user can select up to three radio buttons and click submit. however if they don't select a radio from one of the groups (they dont care to answer the question or just missed it) the value of the radio button (I think) is null and gets returned as such using this code:
function Question1():Object{ return RadioButtonGroup(Q1R1.group).selection.value;}
Then, when they hit the submit button it sends the values to the database. This works fine, but only if they select a radio button for each group. If they missed one I get the following error:
"TypeError: Error #1009: Cannot access a property or method of a null object reference. at mid_fla::MainTimeline/Question1() at mid_fla::MainTimeline/clickHandler()"
When I did a trace on the value of Question1() it returns function Function() {}
how to check if the value returned is a null object reference or whatever and give it a default value if it is?

well i have a problem with my analog clock. i have it in my homepage and now it's working fine, but when i test my movie and click in my portfolio, for example, my output windows gives me this error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at index_fla::MainTimeline/clock() i don't understand because even when i change from page to page (or frames) the clock is still working and everything is ok... but the message keeps appearing till i close my test movie window... and i've noticed that when i go online, there are some files missing that weren't till i had the clock on my homepage.[code]

I am just trying to watch television episodes on my laptop. this error has been popping up for the last couple weeks for no apparent reason. At first, it also said the Flash Player didn't work with 64 bit whatever with IE8. The error said a patch was not yet made and to use IE 32 bit. I did this and am still getting the error. I have uninstalled flash player and reinstallaed it to no avail. This error led to further problems on my laptop resulting in a total crash. Fortunately, I was able to back up all my files before they disappeared. I restored the computer to a time before I started watching television programs on XFinity.com (about a couple months ago) and it seemed corrected for a while and then the error started again. I am given the option to continue or dismiss. either button allows me to continue watching the program, but then repeatedly appears even when I quit XFinity and watch the shows directly from the network websites.

I am trying to figure out the logic to remove a nullreference error that is popping up when an item is not dragged. Inthe code, I have a stopDrag setup for the stage. It works asexpected unless the user clicks the item but doesn't drag it. Itcauses the variable I have set to bring the name of the dropTargetto be a null which crashes the system. I have tried to declare thevariable with a default value but it still doesn't work.It is the targetStop code that it is crashing on. Is thereanyway to default a value so I can do an if / then statement todetermine if there is a value? I've tried: if (targetStop == null)but that doesn't seem to work.
