I'm developing a flex application and I want to access a component by using it's id.
I know I must use .property of the component. The problem is I have the component Id in a String var and now I don't know how to access to it's properties.

Now, this particular MC has buttons on it which work fine. However, when I add a throw component onto the EmptyMC, which basicly lets me drag/throw my attached mc, the buttons are disabled. How can I go about correcting this?
Here is the code for the button on the main timeline:
on (release) {
_root.EmptyMC.attachMovie("Content Def", "Clip2", 1);
}
Here is the code from the component I have attached to the EmptyMC:
#initclip 0
function ThrowBehaviorClass(){
// get the target
var target = this._parent[this._targetInstanceName];
// set up the various properties
[code]....
say i have this code: blah = "123 + i" so blah is a variable right? so how would i refer to this variable? i want to be able to do: _root.blah.onPress = function () but this won't work beause you need an instance name instead, so how would you do this? thx, i hope you understood what i was saying
View 9 RepliesI'm trying to access an instance by using a variable but when I try to manipulate a property to the instance (by referring to it with a variable) it only recognizes it as a string... for instance... (pun intended??)
public var prevbutton:String = "btn1";
trace(["page"+prevbutton]);
// which traces - pagebtn1
trace(pagebtn1);
// which traces the instance class - [object btn1pageclass]
I want to call the instance by using a variable... how do I do this?
I have found a tutorial which shows me how to create a class. It also shows me how to construct an object in the main code. What I want to do is to access a variable from the object that I made. Heres the code...This is the link to the tutorial:http:[url]....
Code:
package
{
public class Car [code]....
Then I use this code to construct the object, which in this case is a car (the code is in my main flash file):
Code:
var mycar:Car = new Car("Porche", 3.2, 4, "Normal doors");
I understand all of the code, but how do I reference a variable like the engine? I have tried lots of things like "trace(this[mycar] .engine)", "trace(mycar.engine) but nothing seems so work. I just get error messages of property undefined.
I am reading a file with certain user defined variables like &x=30&y=50&z=100
Lets the variable is caught in a function as argument myVar
now depending on the variable the user passes I need to fetch the value. ie if the user passes x i need to read the value of x. how the user has named his/her variables.
What i need to do it get the value of that variable by using loadVar.
this.myVar; As such it gives me undefined. There is text present in 'this' myVar represents 'x' I have tried eval(this.myVar) as well as this.eval(myVar) but in vain

View 1 RepliesI have a public variable set within fx:Script tags in a parent component that I'd like to access directly from a child component. How can I do this?

I get a Flex 3 sandbox error #2048 after connecting to a Socket on a Java (1.5) server. The server code is all mine, i.e. not running under Apache. Flash Player 10.0 r32.The sequence is as follows...
1 Java server starts, listens on port 843 for policy file request and on port 45455 for my other requests.
2 Flex client served by Apache (although I get the same result if I run it from the file system), socket connection made on host:45455.
3 Flash Player requests policy file from port 843. This is the standard behaviour with the new security settings looking for a master file. It happens regardless of whether a different policy file has been specified.
4 I serve the following XML from Java through port 843:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" to-ports="*" secure="false"/>
</cross-domain-policy>
5 The player writes the following into the debug policy log...
OK: Root-level SWF loaded: http://localhost/bst/BasicSocketTest.swf
OK: Searching for <allow-access-from> in policy files to authorize data loading from resource at xmlsocket://192.168.2.3:45455 by requestor from http://localhost/bst/BasicSocketTest.swf
OK: Policy file accepted: xmlsocket://192.168.2.3:843
OK: Request for resource at xmlsocket://192.168.2.3:45455 by requestor from http://localhost/bst/BasicSocketTest.swf is permitted due to policy file at xmlsocket://192.168.2.3:843
6 I send a text message from the client to the server on port 45455 using writeUTFBytes() and flush() (this is my own home-baked message protocol, and is correctly processed at each end)
REG/REGISTER;simon;Si
7 Java server thread listening on port 45455 responds with
REG:0/REGISTER:SUCCESS;simon;Si
8 The Flex client receives a ProgressEvent and the event listener I bound to the socket gets called. I process the message (write it to a text box on the screen)
9 The Flash player throws a 2048 sandbox error and the socket is disconnected! This is after the message is received and processed successfully. In fact it is about 12 seconds after. Nothing else works through the socket.
I have tried explicitly loading a policy file with a call to Security.loadPolicyFile() in the Flex client, but the reality of the new player security is that it is basically ignored. The steps are that the policy request will not get sent until a socket i/o operation occurs. At that point the player always goes to port 843 first looking for a master policy file. If it finds one, and it is permissive, it goes no further.
I have tried a variety of alternative ways of terminating the policy file and policy file contents, including deliberate errors just to see if the Flash Player is awake.I can see no reason why I would have a 2048 being thrown. I accurately serve a socket policy file on the designated master security port, which the player itself logs as correct. The socket then successfully sends and receives a message from the server the contents of which are available to my code.
P.S. Please don't tell me to use BlazeDS or LCDS or Granite, or something else as a server, I'm looking for a solution to this problem, not a redesign. And please don't ask me to use an XMLSocket instead - I tried that and get exactly the same result. I have chosen my architecture carefully and deliberately and I want a binary socket.
EDIT :In response to James Ward's request in his comment, here is the entire error message:
Error #2048: Security sandbox violation: http://localhost/bst/BasicSocketTest.swf cannot load data from 192.168.2.3:45455.
I have a stripped down test client which has a handler for each socket event and outputs a message to the screen. This is what it shows:
RequestPolicy: 192.168.2.3:843
Create Socket: 192.168.2.3:45455
Connect: [Event type="connect" bubbles=false cancelable=false eventPhase=2]
Sending: REG/REGISTER;simon.palmer@gmail.com;Si
Receiving: REG:0/REGISTER:SUCCESS;simon.palmer@gmail.com;Si/
Close: [Event type="close" bubbles=false cancelable=false eventPhase=2]
Error #2048: Security sandbox violation: http://localhost/bst/BasicSocketTest.swf cannot load data from 192.168.2.3:45455.
The close event is fired immediately after successfully receiving a response from the server, however the Error #2048 does not appear until about 20 seconds later. If I try and send a further message after close, but before the error, the Flash Player throws an invalid socket exception.

View 1 RepliesIs there a external-source-path option available in Flex compiler similar to external-library-path?

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:

so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.
