ActionScript 3.0 :: Check For Style In StyleSheet Returning Object Where Null Is Expected?
Nov 5, 2009
I'm using the native Flash StyleSheet Object to hold externally loaded CSS styles, and when I run the the getStyle("myStyle") function of the StyleSheet Object, it returns an Object in all cases, even when the style doesn't exist!
In cases where no style is found on the StyleSheet, the ASDocs say that the getStyle() function should return null. So if "notAStyle" is not a style on the StyleSheet, and I test[code]...
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?
I have a weird problem. An Object is being passed to my function, and some parameters are optional, so naturally I would check to see if they are there, and if not, do nothing.However, I'm getting a null reference error (#1009) when I'm just checking it. Here's the sample:
public function parseObject(params:Object) { if (params.optionalParam) trace("Got Optional Parameter!");
I am loading css file in Flex 3 AIR application.

var aaa:Sound = new Sound (new URLRequest ("awd awd.mp3"));aaa.play ();trace (aaa.id3.artist);
The song plays but when I try to get the song's artist / album it returns null. I also tried copying the format from live adobe help website but it still returns null.
Also I have 3 songs named 1, 2, and 3 in a folder. I made a playlist type thing and it works fine, the only problem I see is that I would have to rename 30 songs.
Having to do some as2 with an ancient system, and am far from fresh on it. I've managed to bungle my way through most of it, but I've hit a strange logic problem.
I've been trying to implement a QuadTree to store a two-dimensional array representing a terrain. I generate the array first, then I use the below function to generate a QuadTree for the array.
I have just recently started playing around with AS3 and am pretty new to what is going on in Flash (though I do have a lot of programming experience.) I have an object that I am dragging around on the mouse. I want it to be destroyed if I drop it anywhere but in a target location. I have the part where it is destroyed working, but I am running into a problem trying to find the target. When I try the following...
PHP Code: public function DropObject(){ if (! this.hitTestObject(stage.getChildByName("Target"))){ stage.removeChild(droppedObject); stage.removeEventListener(MouseEvent.MOUSE_MOVE,droppedObject.MouseCursorMove); }}
I get "TypeError: Error #2007: Parameter hitTestObject must be non-null." So, "getChildByName" is returning null, but I'm not sure why. I've verified that there is an Instance name of the Target on the stage. Why can't I find it?
In the platform game I'm making, I have a movieclip level/stage with the platforms (which are there own class) added in. I'm trying to load those platforms into an array for future use, but as I keep on getting null. Take a look at the code:
package { public class StageLevel1Test extends StageManager { private var _platformListCntr:Number = 0;
Ive embeded my game.as file as a movie clip into a new .fla which has 1 frame for the game, 1 frame for the win screen, 1 frame for the loose screen and 1 frame for the intro screen.
So at the end of the game I do MovieClip(root).gotoAndStop(myFrame);
where my frame is either the win screen or the loose screen frame.both screens have a playagain button that returns me to the game frame.Sometimes I get the error after the first win/loss sometimes I get it after I do play again and then when I win/loose.
the error is at:MovieClip(root).gotoAndStop(myFrame);
Im not exactly sure why or how to fix it though any tips?
I'm developing a Flex application using RobotLegs, LiveCycle DS & Java.I'm trying to implement an update function, using LCDS, but I'm running into some strange behaviour:This is the ActionScript code within a RobotLegs' execute command, used to perform the update:
var token:AsyncToken = services.requestService.commit(new Array(model.currentRequestDetail)); responder = new AsyncResponder(resultHandler, faultHandler, token);
If I set an Object = null, does that remove all references to the Object's variables assuming there are no external references to said variables? Or do I have to manually set all said variables = null?
the script i wrote is working fine. but the script attached to the flash player which i have no control over is throwing a script error (im using IE8).how can i fix this? if i run it locally there is no error.
I have the following piece of code(part of a much bigger program). I this code I am re-using a motion that has been previously used successfully. The trace stmts are used to identify the exact location of the error and the error conditions as best I can.[code]
When you cast null to an object using Object(null), the result is an object.When you cast undefined to an object using Object(undefined), the result is an object.But saying null as Object or undefined as Object remains null.Why is this? I can't find anything in the documentation about this.
The objects that result from these casts can have properties set on and read from them. It's as if the cast created information, or removed whatever special information the null and undefined values have. But there's no indication in the AS3 documentation that the null and undefined special types are actually objects.
When working with Date() objects in Flex/Actionscript, I'm using to following function to check for null dates. Is this the proper way to check for a null date or is there a better alternative out there?[code]...
I am trying to add an EventListener to a MC, but I am getting the 1009 error. My script is referencing a MC that does exist. I have verified that my code is typed correctly, and that my instance names are correct.I am creating a portfolio site. On the first frame I have my main navigation (well, it's actually not the first frame. I alpha-fade everything in so it's really the 6th or 7th, but I'm not sure how pertinent that is). The main navigation works fine (5 movie clips, fyi). Clicking them will move to a different frame, and the information and sub navigation for the frame will fade up. It is the sub navigation that I am having trouble with.[code]
As you can see, it doesn't even get to the function before it gets thrown off. I have verified that the instance names are correct. The script and the MC I am trying to add it too [I/]are[I/] in the same frame, which is what's stumping me. Normally you get 1009 when the object you're trying to reference is not there, but mine is!!Obviously there is something wrong with my EventListener. I am not sure what else do; there is a gap in my understanding of AS.
I am new to AS3 and need to gather data from an XML file, parse it and then return all the vars to be used globally. How do I return an object like in the code below?
Code: var dSession:Object = new Object(); function parseXMLData(incomingData:XML):Object
I'm able to return django models that have only CharFields/Dates/Integers, but now I'm trying to return models that have ForeignKey properties and I'm getting this error in Flex in my NetStatusEvent.NET_STATUS onError event handler: m_info Object (@16491fe9) code "NetConnection.Call.Failed" description "HTTP: Status 500" details "[URL]" level "error"
Here are the models that matter in models.py: class RewardActBase(models.Model): user = models.ForeignKey(User) start_date = models.DateTimeField(blank=True, null=True) progress_value = models.IntegerField(default=0) [Code] .....
Then when I want to get retrieve these object via pyamf, this is the method I'm using, which is giving me the error I listed above.: @login_required def get_challenge_act(http_request, location_id): user = http_request.user c = ChallengeAct(); [Code] .....
The interesting thing is that if I change my get_challenge_act method to return a property of the ChallengeAct object, I don't get the error. So I can return properties or objects that belong to the ChallengeAct, but not the ChallengeAct itself. For example, the following code returns a Challenge object with no errors: return c.challenge So it appears that there is some problem returning a Django model with foreginkey models as properties?
I have built a XML decoder that places any supplied XML data into a object and spits it back to the callee.Everything is working so fine, the XML is being parsed, data going into its proper locations... however, when the script does its return, nothing is passed... just a object with no contents...
I have, among many objects, a SimpleButton called nextBtn on the stage on the second frame. There's a function on that frame that does various things, one of which is adding a MouseEvent to that button. After moving to the next frame programatically and returning to the first frame the button is now gone from the stage. Because it seems to be gone, there's a null object reference error where the listener is added.
I've verified that:
- There are no other objects on the stage that share the same instance name
- This happens to MovieClips as well
- If I avoid adding the listener the second time via wrapping it in a if nextBtn != null statement, moving back another frame causes a button on that frame to disappear
I have an object which is assigned a number of properties:
var project_array:Array = []; var slideObject:Object = { project_title : myXML.projects.project[i].title.toUpperCase(),
[Code].....
but I'm not quite sure where to place this. If I place it outside of the object constructor, I get "term is undefined", I guess because it doesn't know what project_clips_array is - but if I declare project_clips_array in the constructor, it appears to need to be defined, i.e. I can't create a blank property. But I can't place it in the constructor either, because it doesn't seem to allow me to run a function within an object constructor. What is the proper syntax or arrangement of code for executing this function to get the array within the object?
