Hi Saveen,
Thanks for the example. its great!!!

This is working fine when called in Application tag of flex but when i m trying to do the same in Module component and calling this module as child of other component it is even not calling my jsp. I checked it in firebug..
Please help me in this issue

Thanks!!!

Great point. You could still do "new Singleton(null)". I still like this approach because it makes the constructor "harder" to call accidentally letting the compiler help with accidents.

I totally agree with your views. I hope soon there could be plugins available with eclipse to see the changes immediately without compiling.

I guess there is already developer plugins for firefox to see changes without compiling the code...

I am glad it was of some use to you :). Cheers!

Hi Saveen,

Yes, it works wonders.

Had been banging my head over upload and file reference with a stupid servlet that was not working.

Thanks a lot !

Dear Phillipi
I see your point. In fact, I remember some friends using IFrames for a similar purpose. Nevertheless, security is an issue (though XMLHttpRequest comes with its own baggage). Extensive use of Javascript based frameworks like Ext and YUI also favors AJAX. The developer would find it pretty convenient to use inbuilt AJAX libraries than using frames here because it would help in populating the UI components faster (unless all components are re-written to read from a frame). Also, discrete and on-demand data fetching may be a bit more complex with frames. Further, RIA includes non-html frameworks like Flex (which are Flash-based) and have their own way of making asynchronous requests.

I think you don't get what I was trying to say...

2010-02-04T07:33:43.215-08:00

I think you don't get what I was trying to say: we were using 1 visible frame for the UI and 1 completely *invisible* frame just for data transport. I don't want those antiquated 1000 frame GUIs back (Jesus, no!), I just described the replacement of an invisible client/server data transport technique that does not interfere and has nothing to do at all with GUI aspects like responsiveness, (pseudo) real-time interaction etc..
This 10 year old frame based data transport is as fast and powerfull as XMLHttpRequest is, the HTML overhead is minimal. Therefore, I could realize literally EVERY modern browser application 1:1 using this approach and without XMLHttpRequest, let it be Google Wave or Google Docs or any other top notch Web 2.0 stuff. Maybe I could do it even better with this!

The only aspect I see different is security, though. Frames have always been a security hole and it's certainly easier to cheat a frame based technolgy like XMLHttpRequest object requests. The browser vendors have learned their lessons, I guess.

Dear Phillippi
RIA has expanded beyond making asynchronous requests. Besides the usual problems associated with frames (http://www.evolt.org/article/evolt/22/293/) , frames are not capable of micro-updates (updating only a row of a table without refreshing the page, for example). They are also not able to respond to user inputs in real-time (can you imagine making Google Wave with only frames?) which makes it difficult to make responsive applications. This has been made possible by faster internet speeds, better javascript engines and improved hardware. So, it is definitely not chic and it is the way to future interfaces.

2010-02-04T02:11:47.166-08:00

Way back in the ancient days before XMLHttpRequest, we did AJAH and RIA without even having acronyms for it, by frequently (re)loading a simple HTML page within a hidden frame. This data page consisted merely of a header with JavaScript arrays and an automatically executed method to inject this data into the surrounding HTML UI, depending on its current context. Worked great and even has a bunch of benefits over XMLHttpRequest: supported 1:1 by literally *any* frameset and scripting capable browser, no evil eval(), effortless browser intrinsic and UI tolerant handling of errors like 404's, if server is (temporary) unreachable, the option to proactively bind additional JavaScript functionality to the data page, initiated on server side, and so forth.
Last but not least, the whole process is easy to handle, to follow/log, and much easier to debug - 10 years ago, Firebug & Co. were tools one could only dream of... Sending payload to the server BTW was attached to the cyclic GET/POST requests that fetched the data page.

Actually, I don't know why we all do XMLHttpRequest based AJAX/AJAJ today and dropped the approach described above… Are there really advantages in doing so? Or is it just chic?!?

2009-07-08T05:42:50.609-07:00

This post is great. It helped me accomplish this same task at work and was quick to find in google.
The following link: http://docs.google.com/View?id=dgdgfsn6_0cwv89gc2 is the same code as before but using only three panels. It implements the drag and drop functionality by doing the operation only at the title area.
It is simply a quick and dirty way to add mouse event listener to the title area and perform the operation if is initialized there.
The DragPanel object I've got it from the source code in this link: http://blogs.adobe.com/flexdoc/drag_and_drop/ For this thing to work one needs to have access to the title object in the panel and title in panel object is not public.

I think this will help more in understanding the object than debugging it. That would be the next step. Once you know what properties are available, you should be able to set up a logger or a watch.

Its returns the same result even though the .php file returns new data upon execution.

myXML.family.child.(@age="2")

That will change the age of all child nodes to 2. And then gives you all child nodes.

What you probably wanted to do:
myXML.family.child.(@age=="2")
