It is possible for a class to extend an arrayList of objects in Flex?
[Code]....
I have a custom java class which has an ArrayList and corresponding to it have a custom vo class which has ArrayCollection (in Flex).I want to return data from Java to flex.Every variable in java is getting mapped to vo perfectly except for ArrayList.When trying to retrive When trying to retrive exposureUSDList (which is an arrayList) in flex I am getting empty ArrayCollection. It is not getting mapped properlyPlease find my code below:
Flex Code:
package com.example.vo

When dispatching events in as3 I always have to extend class from sprite, or movieclip, but when I don't have display objects I don't wont to extend to sprite or movieclip. What is the most light class that I can extend, I mean no display object, and still do use event dispatching?
View 1 RepliesRight away i just try to explain my problem: Using BlazeDS i got the following Javaclasses:
[Code]...
Then i got a Flex service class calling BlazeDS and executing the getCategories java method. Since Flash dosn't seem to understand typed arrays, the result from that method which i get back in flex is a simple array of untyped objects (the mapping dosn't seem to work here, even tought the class category exists in flex and has the same properties).
thats the first thing. but however, i'm converting the untyped objects manually into objects of the category.as class. the second thing is that categories have child-categories within the java object, which are also ArrayLists of the type category.java. the problem about that: my result event object only contains the first level of categories, looking into them the children are allways null. i dunno why they are empty, since they ARE part of the java object category.
and the third thing (the strangest by fast), you maybe noticed i named the properties of the category.java class strange, like idCat and nameTest instead of simply id and name. why that? because the property names of my flex result objects dont seem to change when i change the java objects properties names (result object properties are named "id" and "name" but the java class object properties are named "idCAT" and "nameTEST"). that it REALLY strange, since if i set the properties, like you see at nameTEST = "TESTNAME" it IS recogniced by flex, only the proertyNAMES dont seem to be recognized at all.

I trying to extends ObjectProxy class, the reason is because I want to have a Singleton of the ObjectProxy class, so I made something like
package utils
{
import mx.utils.ObjectProxy;[code]........
when I create my object uniform which is a simple object, I pass it to my UniformObjectProxy.getInstance() static method to get the instance of my objectProxy, ok so far so good.my problem is when I try to bind a property of my objectProxy instance like
_opc = UniformObjectProxy.getInstance(_uniform);
cw:ChangeWatcher = BindingUtils.bindSetter(dispatchColorChange, _opc, data.id);
the dispatchColorChange handler function is called only once an never again, I had check ChangeWatcher.isWatching() and return false meaning my objectProxy is not binding properly, if I create an objectProxy like
_opc = new ObjectProxy(_uniform);
cw:ChangeWatcher = BindingUtils.bindSetter(dispatchColorChange, _opc, data.id);
the binds works just fine, so my thinking is the problem is when I extends the objectProxy class, how is the proper way to do this
I need a way to "extend" or proxy the Number class in ActionScript.Basically I'll overload the toString method of it. But the Numbers should remain comparable with "<" and ">" operators.
View 2 RepliesI'm actually working on a multiple collision detection in actionscript 3.0, using pixel collision for a game for my assignment, where an enemy patrols around and searching for the hero. So, i draw a line between the enemy and the hero, to check whether there's some collision happened between those two. if the line colllides with an obstacle such as wall, door, etc. enemy will not be able to see the hero. When i tried a single line collision with a wall (one object only) it works perfectly.
But here's the problem. For the multiple objects collision (several walls and doors included), i added those objects in an arraylist, When i used for loop to check the collision between the line and those objects in the arraylist, none seems to react , except the first object in the arraylist or index 0.
Is there any simpler way to do the multiple collision detection?
Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?
View 4 RepliesIf I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass:
public class MyMainClass extends MovieClip
fla2.fla has a document class of MySubClass:
public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.
I would like to create an arraylist and i would like to create a search so if the vaules typed match the vaules in the arraylist .

View 1 RepliesSay you were importing flash.events.KeyboardEvent and you wanted it to extend the MovieClip class, is this possible? Where you dont have access to the class to just type "extends XXX"

but since there is no name property on the BitmapImage object, I get errors.I guess I need to put each BitmapImage in an Object and also put in a string as a property of the object, but I can't figure out how to do this. This is my best guess, but then I don't know how to specify the property name for the BitmapImage:
<fx:Object label="Truck">
<s:BitmapImage source="@Embed('../images/menus/car_types/truck.png')" />
</fx:Object>
After that, I guess I would make a custom ItemRenderer to read out the properties on each object?
I'd like to create a combobox which will get users from an arrayList & another field for creating a new user. for example when i open the combobox i'd like to see the rows :
Create new user
User A
User B
where the users come form an arrayList and the "create new user" option is always there.
How can I do it?P.S I don't wan't to add "create new user" obj to the arryList - so this is not a desired solution.
I hope this problem would not waste your time. I use Adobe Coldfusion 9 to create CFC to to interact with database. Generally, CFC can be generate WSDL by itself. for example:[URL]..
The WSDL was generated well. But the problem has been found when I tried to use Adobe Flash Builder 4's Data service to generate service class to connect ColdFusion's WSDL.
If you tried to invoked the remote function that return primitive data type as int or String, it works correctly.

when we extend a class from a dynamci class should we put the word dynamic after extends
for example:
class dynamic Array{}
class myArray extends Array{}
is this a wirte code?
I'm developing a Rails project that uses authlogic for authentication. And I have a part in that project that is realized with Flex, and I need to know how a user can be authenticated if he or she is logged in or not. I've set up a webservice called UserSessionService and I was trying to get the user who is logged in, but it doesn't work. If I try to get it with UserSession.find, I just get a # as the result (and therefore that's always true).
Here's the UserSessionService.rb:
require 'weborb/context'
require 'rbconfig'
class UserSessionService
def login
UserSession.find
end
end
I tried to extend the UserSessionService class from Authlogic::Session::Base, but that doesn't work either.
My flex3 application downloads XML in e4x format from my web server, and and is left as a bindable XML object locally in my flex3 application. My visual objects then bind to various aspects of the XML object to display the data that I want.My simple program is getting more complicated, and I'd like to extend the XML object and add some functions to it, so I can keep the code that manipulates the XML object separate from my base application. Lets call this new object LoginXML.Can I please get an example of how to extend the XML object in flex3/as3 to create my own custom object with it's own functions. Part of my XML looks like
<nodes>
<node id="1">A</node>
<node id="2">B</node>

i have a button class that i use like:
btn1 = new ButtonClass("Label");
i want to extend ButtonClass.but this is giving me an error.
public class EnterButtonClass extend ButtonClass
how can i pass the param?
1) When your class is used to produce anything visual (Put mc's on the stage)
2) When any part of your class needs to use a property, event, or method of the MovieClip class
Ok, I have spent a little time searching and I can't seem to find an answer to my question, maybe I'm asking the wrong question. here's my situation:
I have a document class called Main.as, this class has variables that instantiate a CreateShape.as class that acts as a superclass. The CreateShape.as class has a protected function that is overridden by other classes (I have a CreateCircle, CreateSquare etc). Those CreateCircle etc classes, use extends to extend the CreateShape.as class, and thus have the ability to override the main method (called newShape()).

Just as a technicality, is there ANY object (or anything that can be placed inside of a variable) that does not extend Object?Even the "Class" object extends Object.On a similar note, what is the difference between these two?
[Code]...
I pretty much always use ":Object",but is there any situation where it would be better to use the latter?I also recently found out that there is a difference when using the "as":

I am working on inheritance for the first time. Here is the super class
SetBlank.as
Code:
import flash.text.*;
class SetBlank {
public var _textFieldName:TextField;

I can see the trace function working but the method which sets the text field to blank is now working.
Here is what I want to do...extend the String class Code: class example extends String {} and then I want to take things that are already strings and add a function to them which goes through and removes & and turns it back to & am things got some test code for that here

I am considering using class extension as a way to connect my model with my controller. I tried looking on the internet but could not find any information on this topic. This led me to the question of when a class should be extended and for what reasons.

I've a strange issue. In Flash CS3 IDE, I linked a MovieClip to a SubSimba class. This class doesn't extend MovieClip (it has MovieClip package as its base) but, instead, it extends SuperSimba (that extends MovieClip). What happens? I instantiate SubSimba in my Flash project and it behaves as I if I called super() inside the SubSimba constructor: is there anyone here who understands why?

I come to need a bit more info from my points, so I thought I'd add a previousX, previousY so that I can get a deltaX and deltaY. Now, this works fine if I make a simple self contained class. I think, however, that I'd like to extend the flash.geom.Point class to benefit from the other functions and calculations it offers.
So I extended Point and modified the x and y setters as I needed. When I compile, I get an error that these setters are not marked for override when they should be. So I override, but then I get an error that says these do not override any function.

I was hoping to extend the simple button class in order to have it contain a text field that I can set with code but still have the benefits of the up/over/ states etc... (To set a textfield within a SimpleButton doesn't seem possible with SimpleButton out of the box, you cant reference anything in it).
