I bet this is a headache for all flash developers. Credits for details go to blooddy (http://juick.com/blooddy/563123) but he is too shy q:

#7 Loaders inconsistencies–good critique and attention to detail.

flash.net.URLLoader is a very small AS3 wrapper around URLStream. You can see the decompiled source here:

URLStream, on the other hand, is all native code. You might as well write your own wrapper around it and ignore URLLoader.

Cool, I could add some more..
But it’s quite a while now since I avoid some common pitfalls in Flash because I came to know a few details about the implementation. Like for example Textfield. It is based on MovieClip inside. The AS3 wrappers are at a higher level.

An other :
—-
var tf:TextField = new TextField();
tf.htmlText = “du text “;
var doc:DisplayObjectContainer = tf.getImageReference(“img1″).parent;
trace(doc)//> [object TextField]
trace(doc is DisplayObjectContainer)//> false
—-

WTF ? TextField is not a DisplayObjectContainer, but the variable “doc” can contains it?

For me as3 is great! but sometimes little bugs are around and is a big problem.
I have had problems too with Vector Class, I used to use it as an Array Class, but its methods crash, so I have to use Arrays again.

Recently I was happily using a “for each” and it never read it!, so I have to use a “for”.

greetings! nice blog

Brilliant! Can we suggest our own? Try creating anonymous functions in a loop… it only ever creates one.

Good collection…
And yeah Flash often is weird and sometimes programing for it feels like walking on thin ice… At my new job I needed to adopt to new workflow. Don’t have Flash here and work in Flex most of the time. But assets are prepared in Flash by designers… And boy this is a headache for them and me… Still adopting… May be problems are not as weird as ones you described but often they are… I think biggest problems are that loading SWF from bytearray is nonblocking and there is no way to do it a blocking operation… Would be good if both blocking and nonblocking version of this were available. Another thing is problems with how objects are initialized on timeline… Often they are not yet initialized when you get to frame, or often object it is but it’s own initial on frame script did not kick in yet and designer put something there… Thin ice it is :(

These are great! I’ve been compiling a list of AS3 puzzlers. If I attribute them to you, may I use them for a possible future conference session?

Thanks!
