Javascript :: Flex Ajax Bridge, Or Any Other Push Method With ColdFusion?
Jul 5, 2011
Is it easy to implement Flex Ajax Bridge with ColdFusion? Where can I learn how to use it? My frontend is pure HTML+JS and I just need the push capability. I thought of using Websocket Event Gateway and Server Sent Event (aka EventSource) but seems like they don't have much browser support quite yet. Any pure jQuery short/long polling option Any good Server Sent Event polyfill solution available for older browsers?

I want to use Adobe's Blaze DS via ColdFusion through Ajax. I know enough ColdFusion and JavaScript to do what I want to do, but I want to add long poling into the application and it looks like the only way to do that is through Blaze DS...but I don't know enough about Flash/Flex to finish the job.

My flex project uses FA-Bridge, and apparently in Safari browser I cannot call any of my public AS functions that have arguments passed in. For example I can call this AS function from javascript:
[Code]....
In the above call safari throws an error # 1063, (i.e. Argument count mismatch) in the safari javascript console, and points to line 561 in FaBridge.js. It thinks I didn't pass in the requied parameters. Now the above issue exists only on Safari. Both of the above approaches work on IE, Firefox and Chrome browsers. Note: I am NOT using swfObject for embedding my swf.

I'm involved in writing a Flex/ActionScript library and in the future I will be involved in writing the same library in JavaScript. Rather than writing a library in each language and having to maintain them separately I was wondering if it was possible to:
1) Write the code in one language and share the code into the other e.g. Write the code in JavaScript and use the same .js files in ActionScript
2) Write the code in one language and perform a conversion into the other
I know it's possible to communicate between Flash/ActionScript and JavaScript but I'd like to avoid the overheads in using the technology bridge so this isn't really an option.
How do other people deal with writing and maintaining libraries that do exactly the same thing but in different languages? Specifically how do people do this between JavaScript and ActionScript?

I'm developing a Silverlight4 drop-in replacement for an existing Flash client. I would like to maintain compatibility with the existing Flash HTML bridge javascript functions, but I can't figure out how to expose the javascript interface directly on the Silverlight client object instead of a contained object.
In Flash, it is possible to call Bar() directly on the client object, as in:
var flashClient = document.GetElementById(_currentFlashId);
flashClient.Bar();
But in Silverlight, I haven't found a means to call an interface directly on the Silverlight object. Instead, it appears interfaces can only be exposed on contained objects, as in:

We have a website which displays status updates throughout our various facilities (they all have LCDs with a fullscreen IE page I point it to). Right now I go to my management page with a WYSIWYG-editor, type in the messages/updates, which saves it to a .txt file (alert.txt) and it updates the page on the screens via AJAX. The page on the screens checks for updates at a set interval of 5 seconds. What I want to do now is play a sound to alert when an update is given (the screen only displays critical network errors and such)[code]I've tried adding the sound clip via an embed HTML code (created a Flash object that plays it once upon loading the Flash object) to the text file, but this causes it to play once every iteration. Even if there are no changes.

My company has some software which we use to acquire data and interact with some hardware. If we wanted to put a mockup on a website which allows the user to get a feel for the UI (gather some data, change some settings etc.), what are some good methods to do so?I'm thinking either some clever javascript or flash. I've done some JS before but only to style elements of a page. I did some stuff with flash about 8 years ago and found it really fiddly.
So my questions; Are javascript/flash reasonable solutions for this or is there something better. What is likely to be the simpler/quicker route? Is there a better way to achieve the end result?] The demo doesn't need real data, just some fake/dummy example stuff is fine.

For my current project I am working on a home page that has a series of tabs above a content box that each execute an ajax script to load new content into the content box. However, some of these pages contain a flash object called with SWFObject and when the ajax script calls the page, the SWFObject javascript is not executed and I am left with the no flash support error message.
I have tried defining a function for each video call (short of just designing a single function and passing variables to it) and having the function be called as part of the ajax function but I am left with the same results. I am not opposed to using something other than SWFObject though I have been lead to believe it is the best solution currently.

Is there a way in any browser to find out who (which piece of code) actually sent an Ajax request? What I mean: in firebug one can monitor network activity (in the Net tab) but there is no way of guessing where the request was initiated from.
Does anybody know firefox/firebug extensions or maybe other browser's extensions to show request source (whether it is javascript code in particular file at particular line or browser plugin Flash/Silverlight/etc)?

I am looking for a javascript based preloader that can handle .SWF (flash) files. I'm very much aware that it is possible to preload a flash file by using another flash file, but I was wondering if anyone knows about an AJAX preloader that can load swfs (also, a progressEvent would be a nice extra) and then add the flash file to the HTML document. I did quite some googling but it seems that there is no such thing out there. Is it überhaupt possible?

I have an AJAX web service call that returns a chunk of HTML that I then apply to a DIV element on my page.This works fine for any html element except a flash video which comes up with 'Movie not loaded'.I've double-checked the html that is being returned and it's all fine, and it works if I don't use AJAX, but when I use AJAX and then add it using JS it doesn't seem to attempt to load the playlist.

There is a number of Flash and AJAX based uploaders around. I need a file upload component for an existing form in an existinc application, so I have very specific requirements for it. Maybe somebody knows one off the top of their head and saves me a lot of research.
I need a file upload component that has a progress bar and "upload" button next to it (= standalone functionality, no connection to the submit event of a surrounding form).
It should be either Flash or Prototype based. No JQuery or Moo, as the app runs with prototype.
If server-side scripting is needed, it must be PHP. No Perl, no ASP.
On successful upload, I need a custom Javascript function triggered. (I need to update a file list that is displayed on the same page.)
The possibility of filtering file names before upload (no Umlauts, spaces..) would be a plus.
I will try to give this question a bounty in a minute if I'm allowed to.
Edit: I can't seem to open a bounty. Do I have to wait first?

I have a flex app and I am adding a callback method like this:
private function init():void
{
ExternalInterface.addCallback( "playVideo", playVideo );
}
[code].....
However if I uncomment and run the alert first. I get no error and it works perfectly.My first thought was that the alert was buying time until the script could execute, so i tried to run the script inside a setTimeout() but did not work.

In terms of HTTP request performance should I pick AJAX or Flash? To be more specific, I'm more into Flash than AJAX and I'm currently working on a wide scale web project. I wanted to try AJAX out for once and now it's getting too messy for me. Before it gets more complicated I thought may be I can run Flash on the background for HTTP Requests and use it with javascript. I couldn't find any benchmark on the Internet, but I think AJAX is faster than Flash. So what's your personal experience? Is there too much difference between Flash and AJAX?

I have problems with facebook application based on flash which communicate with PHP using FBJS-bridge.When someone use the application for the first time, he/she is asked for various permissions. After that, flash contact PHP with ajax but request is never sent. When you refresh page, everything is working without any problems.If you remove the application on privacy settings, refresh the page and try again -same bug happens.If you allow application, refresh page, in other tab remove application and start application in previous tab - user is asked for permissions but everything is working after allowing application.This is FBJS code
function openPermissions(){
Facebook.showPermissionDialog(/*permissions string*/, permissionOnDone);[code]......
openPermissions is called to display permission dialog, and on allow flash function allow() is called. In flash, allow() calls JS function ajaxCall(), which should make ajax request. But, ajax.post never sends request. I know that for sure, because flash function parseAjax was never called and also debugging tools in browsers are not showing any ajax requests. URL and parameters are same as when it is working. No flash or JS errors are detected...

I have a flash file that contains a package "game" which has a class "Scores" and a method setValue(). I want to write some lines of Javascript that allow me to call that method. Someone directed me to this tutorial, but I am still a bit confused.
Javascript: alert("start"); var so; so = document.embeds[0];
so.addParam("allowScriptAccess","always"); import flash.external.ExternalInterface;
ExternalInterface.call("setValue[2600]");
displays an alert to tell me that it has indeed began to execute saves the embedded flash file into a variable and sets access imports that class calls the method.I am not sure about how this class thing works? This is just the bits and pieces I was able to come up with from that site, but I don't really understand how it all works (but certainly hope to eventually).This is the site: http:[url]...how-do-i-access-flash-function-using-javascript.When I execute the code with the importation nothing happens, but the alert does come up when I don't have that statement?

We recently built a new dev server for flex builder and installed coldfusion 8. We currently have everything working on our old server using coldfusion 7. We copied the services-config.xml and our project over to the new server. It compiled fine, I updated all references to the new server. When I try to run the flex application I receive the following error:
Warning: Failed to load policy file from http://localhost/crossdomain.xml
* Security Sandbox Violation *
Connection to http://localhost/flex2gateway/ halted - not permitted from file://ourServer/folder/ourProject/bin-debug/ourProject.swf
We created a valid crossdomain.xml file on the localhost (which I wouldnt think would be necessary since everything is on the same server)

So basically what I'm trying to do is make something like this:[URL]... I've searched long and hard to find a site that would show me some pseudocode (at least) or an algorithm as to how to implement this type of application. But everything I find are only applications that take in data and do all the work for me to create the graph. I need to actually create it for myself, just a simple one for now. Does anyone know where I can find this? What I want it to do is take data from a database and use it to create the treemap, then express it in a GUI like in the link above. If any specifics are needed I can provide it. I'm trying to do this in Flash Builder using Flex and using ColdFusion as the backend.

I'm using CF to retrieve values from a database that are then being stored in a datagrid in Flex. I then want to selectively take the value from one cell of the datagrid and store it as a string variable. I've searched around, but I haven't been able to come about a solution. The users will not be interacting at all with the datagrid as it will be hidden to them.

Is the same possible in ColdFusion? Currently I am using .Net/Fluorine to return objects to the client. Whilst in testing I like to pass strings representing the select statement and the custom object I wish to have returned from my service. Fluorine has a class ASObject to which you can set the var 'typeName'; which works great.
I am hoping that this is possible in Coldfusion. Does anyone know whether you can set the type of the returned object in a similar way. This is especially helpful with large collections as the flash player will convert them to a local object of the same name thus saving interating over the collection to convert the objects to a particular custom object.

I'm calling ColdFusion cfc method using RemoteObject method of the Flex.
[Code].....
So you can see that I changed the sequence of the parameter, when I call the cfc method. But it does not worked. It means that <s:arguments> does not pass the named parameter. Is there any solution for that? As you can see that I may have some of the arguments not mandatory so, it must be passed by name.

I have a Flex/CF app that sits on 2 redundant servers behind a load balancer. Both the Flex and CF side make calls to the same CFC. The Flex, CF and CFC are all in the same folder. When the CF code calls the CFC, there's not a problem. However, when the Flex code calls the CFC, it adds an explicit port "84" to the URL.This causes a problem for the load balancer which only accepts traffic from port 80. As I understand it, the load balancer would internally route requests from port 80 to 1 of the 2 servers on port 84 (but that internal routing should be invisible to the client).

Inside a flex app, I have a user login. The login calls a ColdFusion function as a remote object which authenticates the user and, if applicable, returns their id and access level. This works fine, but now I'm at the point where I want to also create a cookie for another ColdFusion template (called from fileReference.upload()) to be able to access later. I have tried several different methods for creating the cookie -- cfcookie, creating a cookie with JavaScript inside the ColdFusion function, and creating the cookie with JavaScript with an external interface once the coldfusion function returns to the flex result handler. All of these have been tried with a plethora of options regarding expiration, path, and domain tags.

I have a scheduling application that allows users to save any changes. When the user clicks the save button, Flex sends all the information to a coldfusion script which picks the information apart and sends saves it to the database. That all works well and good, but I would like to be able to display some sort of text to the user saying something like "Your file was successfully saved" or "There has been an error.
