ActionScript 3.0 :: SharedObject Persisting Between Browser Tabs
Nov 26, 2010
I'm building an online app which opens a SharedObject at its onset to do various things, one being remember whether a user has performed a certain action(vote) before because he/she is only permitted to perform this action once. This is all working fine, until our users began opening a new tab before voting.
If the user opens a new tab, and open the same application, this app(tab 2) needs to know if subsequently the user votes in tab 1. I thought this would be straightforward to resolve. However - for some reason, the sharedObject in tab 2 does not seem to update with updates in tab 1... if you were to refresh tab 2, it would have the updates, but while it is open, the data in the sharedobject does not seem to update.
It all works fine in general, the only time it doesn't is when there are two instances of a flash object open at the same time using the shared object. Maybe this is expected behaviour, and two flash objects can not use the same local sharedObject? It's hard to find this info in the livedocs.
This is the sort of code I am using to manage the SharedObject: (I know the first question anyone will have is, are you the flushing the object after setting your variable, the answer is yes!)
// i call this function at the beginning of the app
public function init(sharedObjectName:String):void
{
sharedObject = SharedObject.getLocal(sharedObjectName,"/");

I have found solution for my previous problem:
onClipEvent (load) {
_root.hitz = 0;
this._alpha = 0;
[Code]....
but now I have a new one! After fifth click browser keeps opening hundreds of new tabs! I think it's because flash keeps playing movie. There must be some kind of loop and every loop flash opens new tab. I tried to add stop(); in few different places but still no result.

In my application the browser window connect with long polling(comet) with the server. If the user open several browser tabs, only one of them(called the master) communicate with the server and serves as a proxy for the other tabs. I want to use flash localConnection to exchange data between the tabs. What happens when a user closes the master tab that holds the comet session? I can use javascript with the unload event to inform the other tabs that the master tab is closing and then close the localConnection but the unload event is unreliable. I can use polling to monitor the master tab connection object but it sound dirty.
When the master is closed one of the other tabs need to become the master. How do I make sure only one of them tries to become the master? If a user close the tab without flash being able to close the localConnection, will it cause a memory leak?

I'm noticing some unexpected behavior. Some time in the last few months, a change in either Firefox, the Flash player, or both, has made it so that Flash movies that are in inactive browser tabs no longer execute in real time. They appear to still execute, but only in bursts, and not in a predictable way. This is a problem because I develop a Flash-based (Actionscript 2.0, Flash CS3) multiplayer game that maintains a network connection and allows players to chat, etc.

So I had been working on this issue where I couldn't get a swf to reload in the same state it was originally loaded. Well further testing leads me to believe that my Model class is being persisted over multiple sessons in the player. Here is my model class:
[Code]...
So when I fire up the swf the first time in the IDE's player, i get 'no previous instance' as you would expect, then I hit ctrl + enter to restart the swf in the IDE's player and I get 'destroying instance'. So this tells me that the Model instance is getting persisted over player sessions. Unless I am mistaken, and correct me if I am wrong, I would assume clicking ctrl + enter (i.e refreshing the swf in the player) would act like a new swf session.

After unexplainable problems with external class files, I'm trying another way of doing what I need to do: an Object variable declared in the fla file. Well, this has its own set of problems. The big picture is: I need to get user data and populate fields in their profile when they sign on. Then save changes to their profile during the session, add new users and make changes to their profiles. Pretty normal stuff.
Here's the problem I'm having with the object.
Frame 1 Script:
/* Define the object to use as an associative array.*/
var Person:Object = new Object();// Define a series of properties.Person.HomName = "Joe";Person.HomEmail = "joe@gmail.com";
Then go to a new keyframe, where I have my fields that need to be populated
Script:
EnterName.text = Person.HomName;EnterEmail.text = Person.HomEmail;stop();
When I compile, I get this error twice (once for each field) "The property being referenced does not have the static attribute."
What does the mean and how do I fix it?
Here is a link to the source file if you care to look.
[URL]
The only way I've been able to get variable data from one script to another is through a _global.variable. Is this the only way? No arrays or objects vars?
Thanks in advance for all who assist. Some day soon I hope to be able to return the favor!

Now, _top, _self, I can't get anything to work for what I want to do. What I'm trying to do is make it so when I click a link, it opens it in the SAME tab. I have seen many (dozens) of these problems, but none seem to help. On firefox, it openes in a new tab, (I have it set so windows open in new tabs), on IE it opens in a new window, and in chrome it opens in a new tab. Please help me fix this problem,

I am fairly new to flash and I have started to attempt to modify a template that I found online to make it my own. The thing that I am having problems with is the URL Links. There are 5 different clickable tabs on the header that I have, and when you edit it in flash cs4, each one is the same image when you edit it. The only way in which you can change what each one of them says is by editing them in the library. This isn't the problem. I want to link these tabs to different pages on my website. When I edit one of them, all of them change to the same url link. The file is too large for me to upload I think.

I can't really understand how can Adobe let the developers release such a messy embedded Flash editor. Please, fix the line copying, it drives me mad. In every normal editor, when u get to the start of the line and press shift+downarrow, the whole line is selected. Flash selects the tabs in the next line also. So pasting is a horrible nightmare.

Well the heading is basically what my question is:
How can I have different colors for different tabs in SuperTabNavigator.
Below is the code to my SuperTabNavigator with three tabs:

y="10"
width="100%"

I want to have different color for every different tab.
How should I do this.
I know there is a firstTabStyleName and lastTabStyleName: is there any way to have the secondTab or the middleTab

Im loading tabs for an accordion control at runtime. The number of tabs is determined by the role of the user. Each tab comes from a module so the load time is variable. As a result the list order changes every time the app is run.Is there a practical way to sort the tabs as each new tab is loaded?

I'm trying to maintain a web applications state across multiple tabs whilst using ActionScript, JavaScript, and PHP. Should I use AJAX to update the database after an item has been purchased etc, or should I prevent the game being loaded if it's already open in a single tab (if so how could I achieve this)?
I'm building a facebook game, when the user buys an item and has many open tabs it doesn't update the state in the other open tabs. The buying of an item is handled by ActionScript, and the storage of that item is dealt with using PHP.

I would like to have vertical tabs in Flex 4. I have started implementing this by having a vertical list down one side. On list selection I am updating the selection index of a view stack. This gives the functionality of vertical tabs.
My problem is the look and feel. How do I get the list to have a similar look and feel to the horizontal tab bar? Is it a case of overriding skins? I have found this post: Flex 4 vertical TabBar
which does implement vertical tabs. My problem with this is that I do not get any text in the tab. I think the problem is that this was originally written for flex 2. I am using flex 4 and am trying to put this component inside a

I am having a problem and hope someone can help. I've created two mc's. One called "mcSkinned" and the other called "mcSkeleton". Each of these mc's has an mc inside of it that acts as the tab (so when the tab is clicked, the focus changes for either mcSkinned or mcSkeleton). The names of the tab mc's are:
mcSkeletonTabBackground
mcSkinnedTabBackground
So this means that mcSkeleton has mcSkeletonTabBackground in it and mcSkinned has mcSkinnedTabBackground in it.I've placed each main mc (mcSkinned and mcSkeleton) on the main scene and added the following code to an "Actions" layer on the timeline:
mcSkeleton.mcSkeletonTabBackground.onPress = function():Void {
mcSkeleton.swapDepths(this.mcSkinned);
};
mcSkinned.mcSkinnedTabBackground.onPress = function():Void {
mcSkinned.swapDepths(this.mcSkeleton);
};
Now, I know that I've done something wrong. Because if it worked, I would not be on here begging for help. Can anyone please let me know how I am screwing this up? have two tabs change depths when clicked on their tabs. I do not want these mc's to be draggable on to change z-depths.

Just learning Flash CS4 and I can't believe you can't create or set tabs in a text object.You can set tabs for editing actionscript, but not in a text object. Are you kidding me? Even wordpad can do this.

I have a site that compiles to Actionscript 2.0 and Flash player 8. This site utilises XML output from ASP.Net driven database pages. The problem I have is basically that where I have some tabstops set, in certain cases, where the text starting from the first tab stop is over a certain length an unwanted line break is output just before the last word in the entry. (I know it's always the last word since if I put another word on the end of the string the word that was originally on the new line is back in it's proper place - so it doesn't appear to be length related).
Effectively, what I want is as follows:
header1: Descriptive text header 1
header2: Description header 2
header3: Description header 3
header4: header 4 text
Descriptive text here across multiple lines
What I'm getting is something like this:
header1: Descriptive text header 1
header2: Description header 2
header3: Description header 3 with a long
description header4: header 4 text
Descriptive text here across multiple lines
The Xml I am loading is as follows (This has been anonymiezd and the angle brackets changed to '[]')
[?xml version="1.0" encoding="utf-8"?]
[config scrollPosition="right" styleSheet=".stylesheetscv.css"]
[text][textformat tabstops = "50,540,590"]:[tab /]T[tab /]T[tab /]T[tab /]:[br /]
[list_by]CV Entries By Date[/list_by]
[Code] .....
There are appropriate closing tags further down the file. The CSS that relates to this is:
headertext {
display: inline;
color: #008000;
} itemheader {
display: inline;
[Code] .....
In order to get the CSS to overide the settings of the dynamic text field I use an empty TextFormat object tFormat. The XML is loaded with ignoreWhite set to true. Or can I not see the wood for the trees?
