I'm trying to implement Gravity from GraniteDS. I did everything like in example from GraniteDS website, but when I'm trying to get gravity from servlet context, ravityManager.getGravity returns null. Here is the code: Gravity gravity = GravityManager.getGravity(contextManager.getServletContext());What can be the reason of this error?
UPD:
From web.xml:
<servlet>

View 3 RepliesI've got an object inside an object. The child object basically loads a variable from SQL into one of it's own public variables. The SQL works 100%, because it traces out correctly.Now I've wrote a function from the child.as
Code:
public get_var() : String
{
return var_yes_friggin_work;[code].....;
Of course the files arn't called Parent.as and Child.as I've just had to rename them because our work is monitored though checking the internet and I can't delete this form.The FilePathOriginal doesn't output anything unless the string is manually set from the child, does anyone know where I'm going wrong here?

I have an ArrayCollection with following structure (when viewed in debug mode):
[0]
- [0]
-- src
- [1]
-- src
src is the path to an image.
I need to get all of the src's out of the arraycollection. However because of the first (unnamed) node I can't take them in. I've tried ArrayCollection[0].children and save the result in another ArrayCollection, however the new ArrayCollection has 2 Objects in it but no 'src'. There are just 2 null objects
firstArrayCollection is filled with the data as described above.
secondArrayCollection.addItem(firstArrayCollection[0].children);
When viewing the content of secondArrayCollection i see following structure (and data):
[0] null
[1] null

ActionScript Code:
public function draw():Card{
return deck.pop(); //deck = array of Card
}
Does not work. Firstly it runs an error which says
"cannot convert [] to Card"...
Shouldn't it pop() return just ONE element?
Then I correct like this
ActionScript Code:
public function draw():Card{
return deck.pop() as Card;
//deck = array of Card
}
And now I get no errors but the function returns null.... why? If I try this:
ActionScript Code:
public function draw():void{
trace(deck.pop());
//deck = array of Card
}
It prints [Object Card] which is how it should be ....

I have a small issue, which is important for my project though. Namely my global var returns null when I need it. I have a global var class:
Code:
package {
public class Global {
public static var premiseGlobalName:String = new String();
}}
In another class I'm setting this var like so:
Code:
public function onButtonRollOver (event:MouseEvent):void {
Global.premiseGlobalName = "My home";
this.addChild(premiseMenu);
}
The second line in the method calls another class to the stage which uses the global var. I trace the global var:
Code:
public function initPremiseMenu():void {
trace("GLOBAL: " + Global.premiseGlobalName);
}
But it returns an empty value.
I want to use the global var in a textfield like so:
Code:
premiseTip.text = Global.premiseGlobalName;
private function getFriends(thisSession:Facebook):void {
getFr = new GetFriends();
var thisCall:FacebookCall;
thisCall = thisSession.post(getFr);
[Code] .....
I have an app where I am looking to make the enter key act like a tab key. I can easily capture the keypress event and setFocus to a textinput field. The problem is figuring out which textinput field to give focus to. I have this code
trace(this.window.focusManager);
//returns TheWindow86.focusManager
trace(this.window.focusManager.getNextFocusManagerComponent());
//returns null
//This is what I was hoping would work
this.window.focusManager.getNextFocusManagerComponent().setFocus();
The code is in a controller class and "this.window" references an instance of a nativeWindow mxml file "TheWindow.mxml". The first trace works as expected, but the second one gives null.
I am trying to create a custom object in AS3 to pass information to and from a server, which in this case will be Red5. In the below screenshots you will see that I am able to send a request for an object from as3, and receive it successfully from the java server. However, when I try to cast the received object to my defined objectType using 'as', it takes the value of null. It is my understanding that that when using "as" you're checking to see if your variable is a member of the specified data type. If the variable is not, then null will be returned.
This screenshot illustrates that I am have successfully received my object 'o' from red5 and I am just about to cast it to the (supposedly) identical datatype testObject of LobbyData:

I'm starting a facebook app using iframe method.I am using flex and so far I am able to connect to fb (login and out). Now I am trying to retrieve current logged in user name. In the document I see this function is what I need. Facebook.getSession().A tutorial in adobe site uses desktop api and it works for desktop (AIR app) but not for web app. (yes, i fixed Facebook.getSession() instead of FacebookDesktop.getSession(); Also, I am able to see the uid but not the user. User returns null. uid is a string and user is an object. But on the desktop app,FacebookDesktop.getSession().user.name returns the name perfectly. but on the web, it does not.

I did a separate levelData class to be able to flexibly add levels. I was happy with it until my supervisor ordered me to convert my levelData into XML. I did an XML version of the levelData's data (question, answers, correct answer...). I used the old class and converted it so that it fetches the XML.
All seems well, I did traces of my answers array and it printed nicely...
But the headache started when I tried this.

// currentLvl:LevelData initialized in the constructor.

I have been developing an application(a website to be more precise) which consists of a flex front end which is constantly sending and receiving data from the back end which is programmed in java.

The Document class loads a list of external bitmap images. As the images are loaded, the following takes place for each:
Code:
var obj:Object = new Object();
obj.bmpData = bmp.bitmapData;
obj.bmpFilename = bmpFilename;
bmpDataList.push(obj);
As you can see, an object is created and the bitmapData is stored inside of it. This object is added to an array.Later, when a key is pressed, a new instance of a class is created. A function is called that retrieves the appropriate bitmapData and this is passed to the constructor of the new instance. Example:
Code:
//Instance is created:
var newChar:BaseChar = new LowA(getBmpData("a"));[code]....
The problem is that getBmpData returns null when the SWF is accessed on the remote server. Result = no images seen. It works just fine locally.

View 4 RepliesI have a mediator that I've registered for a navigation page:
facade.registerMediator(new NavPageMediator(viewComponent));
I'm trying to retrieve that mediator on another page like so:
var navPageMediator:NavPageMediator = facade.retrieveMediator(NavPageMediator.NAME) as NavPageMediator;
However, that statement returns null. If I try to cast it using the NavPageMediator(facade.retrieveMediator(NavPageMediator.NAME)) syntax instead, I get a TypeError: Error #1034: Type Coercion failed: cannot convert com.website.mvc.view.page::NavPageMediator@237560a1 to com.website.mvc.view.page.NavPageMediator.`
I can't, for the life of me, understand why NavPageMediator@237560a1 would be unable to convert to NavPageMediator, nor what happened in between registering the mediator and retrieving it that caused this. Especially since trace(new NavPageMediator() as NavPageMediator); returns [object NavPageMediator].
Incidentally, and this may be part of my problem, I don't understand what the @hash at the end of the object is (@237560a1). Is it simply an internal identifier for that class instance?
Edit:Left a bit of important info: The SWF in which I instantiate and register the mediator is separate from the SWF in which I try to retrieve it.
I have two MC's on stage,
MCmenu is a button array,
MCtext is a collection of text with frame labels. It's labeled as MCtext
The menu buttons tell MCtext to play the frame label as the button clicked. This *used to work*, but Flash was laggy as hell so I updated it. Now the same code returns #1009: Cannot access a property or method of a null object reference. at MCmenu/itemClicked()
Code:
function itemClicked(butn:Event):void {
parent.MCtext.gotoAndPlay(SomeArray[butn.currentTarget.label);
}
I've tried just using a frame number, but still the same #1009
I've tried the Script Assist to target the MC on the stage:
using root.MCtext... still the same #1009
using this.MCtext... returns a #1010
My dynamic text returns null instead of pulling the info i want from my xml file. here is my actionscript and here is my xml. the really weird thing is that i had it working at first. the only thing i changed was the name of the xml file. i used to be called "test" but i needed it to be named something more appropriate so i changed the filename and then i changed the actionscript where it is parsed. so it SHOULD work... but it doesnt. here is what you see instead of the correct info. it seems like the link between the xml and the fla are not communicating with each other anymore, is there anyway i can check to see if the parse is correct?

Because The forums have an issue with me posting code...I posted it here: [URL] Based on this code what is the issue here? why is write always returning false and why is load always returning true? (even for files that do not exist). My understanding is that if flash cannot find the file it should write to it will create it and if it cant load said file, then that method should return false.

I'm having with a menu navigation system. I'm using Flash MX. I have created a menu system for the site I'm building ([URL]) where one of the buttons "Choose photographer" drops down a list of names. All the other buttons just jump to another page. The drop down is currently using tweens also the logo moves to the left as the dropdown appears and returns when the dropdown returns. All working fine apart from its a bit jerky.
It's I just wanted to get away from tweening and use action scripts instead, as I'm a newbie to all things Flash I trawled the net for tutorials and examples so that I could cobble together the exact same effect. I have managed to get the drop down work and return using the action script and it does seem smoother and works slightly better. But can I get the logo to move to the left and back in time with the drop down...no.
