Releases: BlazeDS & Flex Builder 3 Beta 3

Today is a good day for announcements!
I’ve just read the Adobe plans to release, as opensource (LGPL 3?), on labs its Remoting and Messages technologies under the codename BlazeDS.
Moreover Adobe published AMF binary data protocol specifications ( the technology on which the BlazeDS remoting implementation is based).
The source code will be available for download in early 2008

Homework Help Calculator Second announcement is the release on labs of Adobe Flex Builder 3 Beta 3 (M4). Cool, I’m working almost all the time with flex!.. but why only mac and pc downloads are available? The Linux version is still the alpha released on 12 October!

Papers On Technology Actually I almost switched to ubuntu, moreover the fact that there is Flex Builder also for Linux allowed me to spend more and more time on my ubuntu partition and I really feel satisfied. Flex Builder for linux is more and more stable than all the other Flex betas for Windows or Mac ( even if the more I use eclipse and the more I hate it… ), so why give us only that candy?

Flex Canvas bug when it is zoomed in and “horizontalCenter = 0”

Prix Du Viagra Chez Jean Coutu Recently I came across a Flex bug when working on canvas. If you have a canvas with an object centered inside ( horizontal or vertical, it’s the same ) and scale this object the result is that the canvas will clip left and top its contents!
To understand what I mean see this example and try to scale the image:

Paper To Write Online As you can see once the image is scaled and it’s bigger that its parent, you wont be able to see it top left corner anymore. This is an annoying bug for me!

http://aaequipment.net/?dissertation-ready-for-love Dissertation Ready For Love Later I found that someone opened a ticket in the Flex bug management system here: http://bugs.adobe.com/jira/browse/SDK-13009
A couple of days ago I received a notification that the bug has been closed… and incredible they closed it as NOT A BUG!
I can understand that finding the bug in a file with 5000 and more lines of code it’s not easy and can cause horrible headache, but the reason they gave it’s nosense! It’s completely a different thing that the reason of this bug.

Moreover what’s the connection between flash and html?

Cialis With No Prescription Needed Flex have been designed since the 1.0 version as a framework for building RIA (Rich Internet Applications).
A RIA have to behave as a desktop application that runs using the web browser. One of the advantages of Flex agains Ajax is that the first technology provide to the user a behaviour which is much more similar to desktop applications that the one provided using HTML+Javascript. And so my questions is: why should Flex behave like HTML when one of its most important features is to be different from HTML ?
Flex behaves like other SDKs used to develop desktop apps in many situations which are much less important than the one hilighted above. So why close this bug (yes. it is a bug) providing as explanation that it is correct because it behaves like HTML ?

Flex Frameworks

African American History Essay Luke Bayes and Ali Mills of PatternPark made a presentation for the Silicon Valley Flex Users Group (SilvaFUG) of 9 different frameworks and toolkits for creating Flex applications: Cairngorm, PureMVC, ARP, MVCS, Flest, Model-Glue: Flex, ServerBox Foundry, Guasax, and Slide.

PureMVC by Cliff Hall beats out the alternatives
“.

  • Composition over inheritence
  • Liberal use of Interfaces
  • Indirection is used but not overwhelming
  • Instance members hide singleton references from application code
  • MXML views can be extremely thin
  • Benefits of Cairngorm, with few of the disadvantages.

I must admit I never used PureMVC, the only framework I’m currently using is Cairngorm, even if I bookmarked the pureMVC page long time ago promising myself to watch it more in deep. Now it’s time to keep the promise.

FontReader, convert TrueType fonts in graphics with Flex

In the last period I was trying to find a way to convert a TrueType font character into graphics for a new Flex project.
First I found a way using TTX which can convert a font file into an XML with all the Glyph informations needed to recreate the font outline.

But this process requires that all the .ttf files should be converted using TTX before thay can be used in Flash.
So I investigated a bit more and I found a really useful and really well done java project: TypeCast.
What I’ve done next was just to do a porting of the available java code into Actionscript 3 and it works like a charm! It can read a .ttf file and extracts all the font informations, including all the glyph outlines.

See a demonstration Quantitative Research Sample Paper of thie Flex application.

New Flash player 9,0,45 & Flex patch

If you’re a Flex 2 developer you should download the newly released Flash player 9.0.r45 debug version.

Once installed the new player remember to apply also this patch to Flex builder 2, otherwise it will throw you an error every time debugging an app (expecially if you’re using Firefox).
This patch also does the following:

“This patch allows the Flex SDK and Flex Builder to use SWFs and SWCs created by Flash CS3 Professional. After applying the patch you should be able to take classes and symbols compiled with Flash CS3 Professional and compile them into a Flex application. You should also be able to take classes and libraries compiled with Flex and use them in a Flash CS3 Professional project.

In addition, this patch allows the Flex debugger (fdb) to function correctly with Flash Player 9 (9.0.45.0) in the Mozilla browser.”
