Re: [flexcoders] Re: Every second time I debug my app, Flex closes Safari :(
Yep or close the window with the app before re-launching the debug session also works as well. FB on OSX has a lot of drawbacks - on win, the help gets its own window (so it doesn't get killed by the debugging), syntax colouring works better, images actually appear in design mode all the time, it builds a lot faster (iMac in BC spanks my mac pro in OSX), the text editor doesn't lag when doing fundamental things like selecting text. Oh and I love it when FB seems to get confused and tries to launch a debug session but in reality it's just sitting there and waiting to time out. At least embedded fonts still disappear on both platforms in between compiles for no apparent reason so I don't feel completely screwed over. If it was edge case stuff, it wouldn't be a problem, but this is stuff you have to put up with every couple of minutes. Nik

[flexcoders] Production inefficiency
Hi All, For those of you that are using lots of flash CS3 swf's, what is your folder organisation and publishing process ?? Right now we have everything including project folder ~/Documents/Flex Builder 3/Proj/ under subversion control. Everything that we want to publish (to localhost MAMP in this case) is under src/. The fla files are kept out of that src/ folder and have their publish settings set to publish into the src/swf/ folder. fla/ assets.fla src/ Application.mxml amfphp/ components/ AIRenderer.mxml crossdomain.xml remoting-config.xml services-config.xml swf/ assets.swf html-template/ However... the only reliable process to view a change in your CS3 swf's becomes: shift+F12 from flash (Publish), switch to eclipse, right click in Flex Navigator-refresh, cmd+B, switch to safari, close any window/tab with flex app in it, cmd+opt+e to empty cache, switch to eclipse, cmd+F11 to run your app with new content displaying. without the refresh, eclipse will not pick up the changed swf files. F11 will run the app, not copy across changed files. without emptying the cache in safari you will often get cached content (even though we are pulling in our swf's with a querystring parameter). without closing the window in safari, on F11 the applescript will close your freshly launched app window (along with all your help docs/ blogs/research). using firefox instead of safari means that you can't launch help as it errors out saying that firefox is already in use. eclipse will also not copy across empty folders (even though you need them in our output folder). Someone kindly point out a better way of doing this. Regards, Nik

As Amy suggested the filtering does help, but mine now searches more intelligently even when the scope is changed back to all. Although it says it does it's indexing first up, I am still inclined to think that it still modifies or alters it's index later on, as DisplayObject now returns the class definition as 4th item and Properties and Methods of DisplayObject as the first item. I created a search scope that had just the refs, perhaps that forced it to clean up some ? Still doesn't resolve the browser window closing and browser blocking issues related to launching help and googling is far less useful considering the amount of cross over between flex 2/3 and flash and general AS3.

Hi, Does the profiler only report memory usage for the swf it is profiling and not the total memory for all swfs that my app loads in ??

Re: [flexcoders] AMFPHP and date/datetime data from MySQL
Sajid,
Still under a tight deadline atm, but this is what i have working for
me so far:
To write it to DB:
public function create($obj)
{
$query = INSERT INTO Event
(
DateStart,
)
VALUES
(
'.date(Y-m-d,mysql_real_escape_string($obj[DateStart])/1000).'
To read it back out - the query:
public function getOne($id)
{
$query = SELECT
date_format(DateStart, '%a %b %e %T GMT+1000 %Y') as DateStart,
Which will format the string exactly as new Date() outputs for me
(couldn't quickly find a way to get the timezone + offset so it's hard
coded).
Then in my VO which is sent back via amf:
?php
class EventsVO {
var $_explicitType=vo.EventsVO;
public $_DateStart;
public function EventsVO()
{
}
public function mapObject($data)
{
$this-_DateStart = $data[DateStart];
}
}
?
Take note that I have prepended the VO DateStart field with an
underscore, the reason for this is apparent in the .as VO below:
package com.aom.mfl.vo
{
[RemoteClass(alias=vo.EventsVO)]
[Bindable]
public class SEvent
{
public var _DateStart:String;
public function SEvent()
{
}
public function set DateStart(val:Date):void{
_DateStart = val.toString();
}
public function get DateStart():Date{
if (_DateStart == null){
return new Date();
}
return new Date(_DateStart);
}
}
}
Effectively the remoting will set the string of _DateStart but all
other code throughout my flex app will refer to DateStart which
returns the true Date object, you could create another private field
to hold the Date object instead of parsing the string version on each
request.

[flexcoders] AMFPHP and date/datetime data from MySQL

[flexcoders] Get all class definitions in a loaded swf ?
Hi,
Is there a way to load all the class definitions in a swf that load
into my flex app ??
On a sample swf with 4 mc's named mc1,mc2,mc3,mc4, i have got it to:
private function onSWFLoaded(event:Event):void{
var col:ArrayCollection = new ArrayCollection();
for (var i:Number = 1;i = 4;i++){
col.addItem(event.target.applicationDomain.getDefinition(mc +
i)
as Class);
}
var mc:MovieClip = new (col.getItemAt(0)) as MovieClip;
trace(mc);
}
Which works with instantiating the loaded mc, but i want to get rid of
the dependancy on getDefinition() and having to pre-know the class
names. Be incredibly handy to be able to utilise my external swf's as
asset containers if i can do this.
Cheers,

Re: [flexcoders] Re: No Scroll Bar in Browser
Out of the box Flex defaults to content being unviewable if the content is larger than the content window. There is no use case where this is desirable.

[flexcoders] Stop Flex closing whole browser
Hi, So you have a whole bunch of pages open for your docs and samples, you compile your app, it launches and then hits an error and throws you back into debug mode in Flex. Sometimes when you press interrupt it will close the browser window instead of your flex app tab and you lose all your docs and references. Every time, without fail, if you do not close the previously launched flexapp tab, Flex will launch the newly compiled version and then half second later close the entire browser window. This is with Safari on OS X. This is such a productivity killer - is there some patch, hack, setting that i can change to stop this from happening ?? Regards, Nik
Re: [flexcoders] Help with binding (flex 3)
I have run into the same issue. My RemoteObject calls are already set
to makeObjectsBindable so that doesn't seem to be the issue.
Basically, if i have a view that is already displaying the bound
object, then do a remoteobject call that replaces the existing bound
object with a new one, the bindings do not update. Which makes sense
as the replacement instance would not have the bindings of the current
model object set on it. Instead, I have resorted to copying the props
over to the existing model object so that the bindings and references
stay intact, using this script:
public class ObjUtil
{
import flash.utils.*;
public function ObjUtil()
{
}
public static function CopyProps(source:*,destination:*):void{
var def:XML = describeType(source);
var properties:XMLList = [EMAIL PROTECTED] + [EMAIL
PROTECTED];
for each (var property:String in properties ) {
destination[property] = source[property];
}
}
}
And is used like this:
ObjUtil.CopyProps(e.result,userModel.currentUser);
It is not immensely robust and still feels like i am missing something
in regards to binding - but this works without a whole bunch of extra
typing for each and every property that needs to be updated.

Re: [flexcoders] Problem with Subclipse...
The ignore option operates on a file/folder level in your working copy. Right click on an item in the Flex Navigator pane, go down to the Team menu and then select Add to svn:ignore. With regards to why something should be excluded - mainly because there is no point. When you commit a source revision, it should contain everything needed to create the output binaries (source files, resources, compiler/project settings etc). The only thing you gain by putting your output folders under version control is to have more stuff bloating up your repository. Even more annoyingly, you will end up with a dirty working copy that gets committed where nothing has changed except that someone rebuilt the project - this clutters your history and forces other team members to do an update where non was needed. This is not specific advice for Flex, this is pretty much given for any development environment under version control. Regards, Nik
Re: [flexcoders] getChildByName using it to get the value of a textbox
You need to cast it to the type of object you want to operate on: var test:TextBox = this.getChildByName(inputtext + 1) as TextBox; or var test:TextBox = TextBox(this.getChildByName(inputtext + 1)); The first form will return null if it cannot cast the displayObject to that type as opposed to the second which will cause an error. Of course the Eclipse help system is so utterly useless that searching for 'as' will return nothing and displayObject will not be in the first 3 items you search for. Regards, Nik
Re: [flexcoders] Re: getChildByName using it to get the value of a textbox
That #1009 error means that it returned a null from the first line
because it couldn't find the child with that name. getChildByName is
not recursive so you need to be mindful of the nesting of your
requested object.
The following app has the functionality working as you need it, but it
also has a really handy listing function that displays all of the
current children recursively (outputs to the console window in Flex,
if you have the debug player) so that you can see the children that
are present and how they are nested.

[flexcoders] Project Clean/Build All
Ok, someone let me in on the secret. I do a project clean, verify that yes it empties out the directory except for the folders. Build All... for some reason it doesn't copy across ALL of the swf's. It used to. There is only one option on the Flex Compiler properties page to 'Copy all non-embedded files to output folder'. It is checked, and has been since the beginning of the project. Machine reboot etc doesn't fix this. Is Flex trying to be smart about what it copies ? Is there someway that I can force a copy of all files ? Secondly - We have fonts, with exported classes sitting in swc's that are then referenced by css on components. Compile first time, no problems text appears in the components, compile again after making no changes whatsoever to any source files. Text disappears from all components that reference it. Why would this happen ?, How can I stop it from doing that ? Regards, Nik
