mxmlc NullPointerException crash

Alessandro Crugnola flex , , , ,

Today I was getting crazy to find out why Flex didn’t want to compile my application.. Clicking on compile it started suddenly to give me an internal compile error and nothing else. So i tried to compile with the mxmlc from a console just to see the error log and the outpuw was:
java.lang.NullPointerException

Wow!!
So, how can I find the problem? I can’t find any useful information from this log..
For this reason I had to remove portion of code from my mxml and from all the imported packages.. 2 hours of “debugging” gave me the solution!

A syntax error in a declaration of an XMLList was the problem!  Fixed the line also the compiler started to run again with no problems.

This is a portion of mxml code to reproduce the problem:
;

< ![CDATA[ private var uuid:String = ""; private var menubarXML:XMLList = <>
<>;
]]>

Strange issue with Flash Updater 7.2

Alessandro Crugnola actionscript ,

I got this very strange behavior (let me say BUG) with the new flash updated version 7.2, and which drove me crazy for a while!

Create a new document, settings set to flash player 7 and AS2.
Create in the document a movieclip with exporting settings, export for ActionScript, and give the name “mc”. Delete the movieclip from the timeline.
try the code:

depth = _root.getNextHighestDepth()
trace(depth);
_root.attachMovie('mc','mc',depth)
mc.onRelease = function(){
this.removeMovieClip();
}

you will get a “0” in the trace output and once click on the movieclip, this will disappear.

NOW.
Drag a component on the stage, for example the tree component, and then delete it from the timeline. This is just in order to have it into the library.
Test the movie again.

I get in the trace output the value of “1048576” and the movieclip does not disappear now!

incredible!

undefined toString??

Alessandro Crugnola actionscript ,

One of the things that it has always made me laugh on the new Flash AS2 is the translation of the undefined value (mmhh.. not a value, it’s undefined!).

a = undefined;trace(a.toString()) // undefined

b = a + " is not a string"trace(b) // "undefined is not a string"

???
Probably I don’t yet understand the strict data typing concept (quite sure), but undefined CAN’T be converted to "undefined".
It’s so Stupid for me!
