It was pleasure being on JavaRanch’s forum and I enjoyed interacting and answering member’s questions.

Thank you all.

In this chapter you will learn basics of working with XML data using E4X techniques and various XML classes provided by Flex 3 E4X API. You will also learn how to load external XML documents and manipulate it in your Flex application. This chapter will also provide you a comprehensive example for building a book explorer application using external XML data and E4X techniques.

I hope this chapter will serve a good purpose for solving some of the most common question asked by many Flex developers on how to work with XML data in Flex.

From This:

private function foo():void

{

   if(…)

   {

         …

   }

   else

   {

         …

   }

}

To This:

private function foo():void {

   if(…) {

         …

   } else {

         …

   }

}

I agree that vertically spacing parenthesis style is easy to read but again depends on how you look at it and individual taste. But it doesn’t work sometimes.

When I first started to work on Flex 1.5 I faced many problems but one of the particular problem which forced me to switch my liberal way of writing code to writing compressed code (I mean positively). The error is commonly known as “The 32k Error”. The Flex 1.5 compiler seems to consider empty spaces and commented lines while compiling code and sometimes this caused nasty compiler 32k Error. There are many reasons why this error would pop up during compilation and not all are known, however most common are:

1. Number of code lines or file size.
2. Using too many nested looping statements and process heavy data in it (I don’t know why)
3. Or any other reason you might find… (they are not know to me)

Once we encountered this error then it took us days or sometimes weeks to figure out what is causing the error and how to rid it, but over the course of time I learnt that major cause is number of lines in your file so better write a code vertically compressed manner and remove commented or unused code and split large files into many small AS files.

Today I am so used to writing vertically compressed code that I think it is the faster (you save hitting Enter key ) and best way to maintain your code in a long run and its best way to save space (not that you have to pay for space, but you never know).

Keep Flexing.

There are mainly two aspects to this question first developer and second customer/businesses, my opinion is kind of mixed of both. There is valid questions raised during this discussion as “RIAs are application not the content, hence cannot be seen as content holder as HTML. Does your desktop search index your desktop applications?”

First half of this statement is absolutely correct that RIAs are the applications BUT if your application is on internet then it is bound to deals with the content and if it is dealing with content then it becomes mandatory for enterprises to have it search engine friendly in order to increase “visitors + business + revenue”. That is why we call it Rich Internet Application (RIA).

I would like to quote statement stated by Chuck Frazier on flex-india thread, he says “RIA’s are applications and Flex has allowed my website to operate much like a desktop app. I love it for that reason. But if no one knows I exist, then it doesn’t matter how fantastic my website is. It would be like cooking a wonderful banquet, but I didn’t send out invitations to my friends. So the fact that SEO and web crawler techniques do not apply well to Flash / Flex is definitely a concern for anyone that wants to make money with their website.“

And this is definitely a concern and deciding factor for many enterprises to choose flash/flex as front end technology.

In desktop world the “visitors + business + revenue” factor is not there and hence it is not required for them to be indexed.

I love flex as much as any flex evangelist would but I do not want to see swfs used only for animation or as applets, today how many are using applets, when SUN released it as an internet applications technology (Applets are used to provide interactive features to web applications that cannot be provided by HTML), and to avoid applet like fate we need to make swfs more content friendly, swfs have to leverage html capabilities and continue improving and evolving RIA platform.

My personal experience, it is difficult to convince your clients saying that flash/flex is not SEO friendly and you cannot treat them as HTML. However there are some techniques available such as Ted Patrick’s post about writing wrapper around your swf content for making it accessible to search engine crawlers. Also go through InsideRIA post about Google is using Adobe’s Search Engine SDK to crawl through SWF content.

It is very interesting to see how swfs get evolve in future keeping in mind applications and content friendliness. As Chuck says “I somewhat agree with Abdul about the content versus app issue, but at the same time I think we’re looking at an evolutionary jump that will blur the lines and make those ideas less applicable to the “new Web” that Flex developers are creating.”

I would like to hear your idea/opinion on this question.

a. Adobe is sponsoring this event.
b. Adobe is giving away raffle copy of Adobe Flex Builder 3 Professional.
c. Adobe is about to release Adobe Flex 3 and Adobe AIR 1.0 and this will be the focus of this meeting.

Flex 3 is a feature-packed release, adding new UI components like the advanced datagrid and improved CSS capabilities; powerful tooling additions like refactoring; and extensive testing tools including memory and performance profiling, plus support for automated functional testing in Flex Builder 3.

Adobe AIR is game-changing in so many ways, delivering rich Internet applications (RIA) on the desktop, enabling access to the local file system, system tray, notifications and much more. Now you can write RIAs on the desktop using the same skills that you’ve been already using to create great web apps including both Flex and AJAX.

The details about venue, speakers and topics yet to be decided. Keep watching Flex India Topic or Mrinal’s Blog for updated information.

Now I just hope that my blogger redirection to redirect traffic from blogger to my new blog will work for MXNA too. (Fingers crossed).

Edited: Redirection is working and MXNA is able to pick my posts
