ActionScript 3.0 :: Storing Dataprovider In Shared Object?
Mar 31, 2010
I'm having trouble storing a dataprovider in a shared object. Writing the dataprovider object to my local shared object seems to work fine, but when I try to read this out of the shared object, it appears to have been transformed into a generic object. When I try to assign a local dataprovider variable to the dataprovider I've read out of the shared object, I get the following error:
"cannot convert Object@3721e6c9 to fl.data.DataProvider"
I am having problems storing an array of objects, all of which are the same custom class in an LSO and then reloading that array from the LSO without losing the class type of the objects in the list.
I know how to store a single object of a custom class and load it withe the correct class type using the registerClassAlias() function, but I cannot seem to apply this to arrays of objects.
I am trying to save an array called messageList. Each element is a custom class GameMessage with a property called gameLevel. After I load the LSO I am trying to do something like
trace("0th message is from level " + GameMessage(messageList[0]).gameLevel);
And I am getting an exception of like this:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@90fdfa1 to GameMessage.
I have registered the GameMessage class using
registerClassAlias("GameMessage", GameMessage);
and everything works if rather than a list of messages I try and save/load a single message.
Is it possible to store instances of a class in a cookie or in shared objects.
Basically in my application I have an object "Diagram" that the user can create. If they hit save, I want to store the current instance as a cookie and allows them to reload it later.
Alternatively, I could see about getting them to store the saved version on the hard disk. But even then, all I want to save and retreive is my actionscript object.
I've tried storing the object to SharedObject.data.diag, but when I try to retrieve the object from the cookie doing SharedObject.data.diag as Diag returns null.
I'm using a loader for people to use to upload their own images for a background, and I want it to remember the image the next time they come to the page, so is there any way to save the loader data in a shared object? I haven't tried just using something like
I've got a pretty complex XML file that I'm trying to process and I want to store all the results in one custom object. However, I'm having trouble getting past the first step. I want the object to have this basic format:
I've always wondered if there was a way to retrieve and store the current position of an object. i am trying to develop a background slideshow using penners equations. but i get into trouble because you have to define the start position. so let's say you click button 1, and the object moves from x =0 to x = 200. Now when i press button 2, i want the object to move from x = 200 to x = 400. and if i then press button 4, i want it to move from x=200 to x=800 and so on. So i need to go from the current position to any of the new positions. i could do this simply using the normal inertia code.
In Flex I can create an ItemRenderer to represent each item in the Lists DataProvider but how do I access the instance of the ItemRenderer via the DataProviders Object? Something like myList.getItemRenderer(dp.getItemAt(10));
I drag the combobox from the library and set the dataProvider through AS.however, I click the combo, the options show, I click an option but the value doesn't change. it's like I clicked outside or something, it simply stays with the same value there.
example:
[option0][v]
*clicks the v arrow*
[option0][v][code]......
I simply drag the object, give it an instance name and set a dataProvider, nothing else.
I am trying to use JSON decoded as a dataProvider, but no matter what I try I get errors such as the following: Error #1034: Type Coercion failed: cannot convert mx.collections::ArrayCollection@2a88ae01 to fl.data.DataProvider.
Can I use Flash Shared Object to pass information between two different SWF files on two different pages within the same website?I know it can if the SWF files are the same. But what if they are different Flash object with different SWF files?
I was thinking if there was a way to remove the shared object pop up from popping up lol?Its because Im making a game where when the player saves the pop up comes up over a 100 times and it's really frustrating, so I was thinking if you could remove the pop up entirely by using actionscript?I've found a script that shows the popup:System.showSettings(1);So is there a way to reverse this script? like System.hideSettings(1); ?
I have a client who has a video that is to only play once when a user visits. So I created a shared object to create a param that the video has been played. It works perfect locally and on my live test site. However when the client posts it on his ning website in the header it doesn't work. The strange thing is that live and locally on my server you can see the shared object and it's size through the advanced tab in Flash's privacy settings.
I have a gane that uses shared object and keeps note of highscores and users names. So - if that is possible then I can set up teaching courses on standalone pcs can't I? ie: Databses I have in access can go in XML and the recording of position in course and results of tests can also be recorded using Shared object.Is that a good way of going about things OR should the whole thing go over to AIR and its sqlite system?
I have 2 ways of accessing info in my course files (SWFs): text-only and audio playback. I'd like to use shared object to store the user preference so it remembers the setting when navigating between screens. It stores info file but each file creates its own shared object.
for example: <path to the swf>page1.swfcoursename.sol <path to the swf>page2.swfcoursename.sol <path to the swf>page3.swfcoursename.sol
Since it writes and reads the SOL file of its own folder, the user setting isn't remembered when switching pages.
I am running a chat program which displays a list of users along with their status (online or offline). I wish to remove the list and display their status in their respective biographies, which are separate swfs. The usernames and status are stored in a remote shared object as an array.My question is, what is the most efficent way of extracting an individual user's current status from the SO array?[code]
I was trying to obtain data I wrote using a sharedobject location from one application on another, but it didn't seem to work(used same machine). So I take it local stored data is only allowed to be accessed/manipulated from the application that initially wrote data to it?
Is this is for security reasons? Is there anyway around this, I want to have one application read variables from another...
I am building an application that uses a Shared Object that is shared (ironically) between 3 separate applications. 1 application listens for updates, and the others update the app. The problem I am having is that I need the main application to be able to detect changes to the Shared Object. Unfortunately there seems to be no events to listen for that are not for 'remote objects'. Because of this I created a timer that gets a new local instance of the shared object every X seconds.I just call the following before I read or write to the sharedObject:[code]This is causing a CPU Hiccup every 3 seconds and bogging down the system. so all this being said, does anyone know of a clean way to refresh a copy of the sharedobject without creating a brand new instance of it
read a local shared object with a servlet even if there is no flash present on a page? I want to set a local shared object like a cookie, and then access it again from a page that doesn't have a flash movie.If I can't do this, is it standard to have the initial flash movie call an external javascript to set a traditional cookie that can later be read?
I have a Flash.exe projector that stores data in a Shared Object. Anything works fine if I launch it from my desktop. The Flash.exe will be recorded and used from a CD-rom. Will the path of the Shared Object change? Say, will it try to record itself on the cd?!
I want to let the user save some bigger data in a shared object by choice. Is it possible to define the size the user needs to allow? I'ld like to set the minimum to at least 10 MB to have some extra space for future usage.
