You have to make sure your hands are lined up so they're displaying  
in green pixels on the edges of the frame (where the panels are).  It  
works best if you hod your hands parallel to the keyboard so you're  
only tracking a single lump of green pixels.  if you're moving too  
much or your shoulders and elbows are filling the shot then the  
camera gets confused.

Hi all,



   i'm new to this list, and to flex and flash. I've  
just posted my first experiment with flex up on the web and if  
anyone has time to examine it and would like to offer any feedback  
I'd be very grateful. It's a very simplistic pong game, where you  
can control the movement of the paddles up and down by waving your  
hands in front of the webcam. I wrote it as a proof of concept, and  
in doing so tried to learn about the bitmap API and various things  
like filters and matrices - making use of the excellent tutorial by  
Guy Watson on webcam motion tracking. Code is posted, so if it's of  
any use to other noobs like me please feel free, and if anyone can  
tell me where I might do things better I'd love to hear from you.




cheers,

Toby

Betreff: [flexcoders] Re: Not able to generate GUID

 


Thanks for the reply... i probably will look into writing my own 
implementation. Never really thought of it...

Generating GUIDs on server, while i can do that, just makes more 
sense if it's done in the flex app itself.

and yes... these IDs will be used as primary keys in my database... 
at least that's the current design i'm thinking about.

I'm generating an XML document in my flex app, where each 
node/element and its attributes represent a single row and child rows 
in a parent child/foreign key relationship.

When i call a web service, i get my xml document which contains pre-
existing primary keys but when i add elements that have not yet had 
been persisted to the database i don't want to both send up my xml 
data and then turn right around and pull it back down just so my new 
xml elements/nodes have the correct primary keys attached. That's 
especially important when i save/send up the xml a second and third 
time.

If i can assign my IDs earlier in the process, that solves that 
issue. I still have to check pre-existence on my server side when i 
actually commit my changes to either run an insert or update sql 
statement.

Found the problem.

It appears that the upload code works differently on a linux player.
The exact same code works as advertised on windows/mac players.

I tried getting an update from Adobe, and got the latest player for
linux (FP9_plugin_beta_112006.tar.gz or Shockwave Flash 9.0 d78) and
it did not fix.

[flexcoders] Show\Hide Column in DataGrid

[sanjaypmg]

Hi All,

I am facing an Error while making Grid columns visible\Invisible at 
runtime.

I have made a function showHideColumns in my application which accepts 
2 arrays as parameters. One is "colNameArr" Which has all the column 
names of GRID and another one is "colStatusArr", which has TRUE or 
FALSE corresponding to that partifular column.

When I call the method "showHideColumns" It is making the column 
visible\invisible but showing an ERROR also Which is "Cannot Create a 
Property on String".

How Can I remove that error? pls suggest me something. the function is 
given below:


**  FUNCTION   *
public function showHideColumns(colNameArr:Array, 
colStatusArr:Array):void{

   for(var i:int=0; i

[flexcoders] Problem with Content spilling over beyond it's container's bounds

[Mike Anderson]

Hello All,

I have an irritating problem with a draggable TitleWindow, that houses a
UIComponent w/embedded SWF.

My Custom Class extending a UIComponent embeds an external SWF File,
which gives me the ability to wrap it with code.  This way I can control
the SWF and all the MovieClips it contains, programmatically.

Basically, upon the initial Load of the UIComponent, it exceeds the size
of the TitleWindow - and instead of the TitleWindow Container masking
off the extents of the UIComponent, it literally lets the entire SWF
File show through.

Now if I trigger a Resize Event by actually sizing the TitleWindow (I
have code in place, that allows the user to resize the window), THEN the
TitleWindow immediately clips the Content properly.

The UIComponent can be controlled by the User, via a Slider Control
(which controls the Zoom Level), and the user can also pan the Component
around via startDrag() and stopDrag().  Because of all this potential
interaction, it's imperative that the Content's Parent Container,
properly clips the parts that should not be showing.

So with all that said, is there anything I can do differently, to ensure
that the TitleWindow always clips the Children that it houses?

Thanks in advance for your help,

Mike

RE: [flexcoders] Flex Player 9's (Flex 2) Memory Usage - What's Normal?

[Matt Chotin]

Funny you bring this up, it came up in a separate discussion today.  We
don't have a "typical" memory usage for a Flex app, it really depends on
what kind of work your application does. Do you load lots of images?
Those can take up space.  How many components do you have, do you load
them in a deferred manner or all at once?  One thing to remember is that
the Flash Player allocates memory in chunks, and it may not release
memory until enough has been allocated to force it to GC.  So let's say
it allocated 40 megs.  If the app happened to get to 33 megs there may
be no need for the Player to GC.  And it could be that in reality the
Player could get away with only 20 megs, but it will take that whole 40
b/c the OS is letting it and it.  Still not technically a memory leak,
even if you think the task manager should show less.
 
Remember to remove children from the display list.  Remember to remove
event listeners or use weak listeners where appropriate.  
 
Hope this helps,
Matt

Subject: [flexcoders] Flex Player 9's (Flex 2) Memory Usage - What's
Normal?



So I'm developing what will be a good-sized application, but I'll be
carefully planning for download speed and runtime efficiency through
ModuleLoader, SWFLoader, etc. 

Right now I've barely begun but have finished the ground level for the
Data Retrieval, Normalization and Management (no FDS). The memory
monitor object shows about 40 megabytes of memory being used when the
data comes in, and drops to 24 MB if I leave the app still for a a
couple minutes afterward (I assume that's garbage collection kicking
after the data normalization). 

Flex is one my first forays into needing to worry about things like
memory management, so I'm looking for best practice and a baseline of
what's expected and acceptable. 

1) What's "average" memory load for a Flex application? When do I
start freaking out about using too much memory? 

2) How do I optimize memory management during run time? What's the
best way to encourage good garbage collection? 

Ideally this app will cache the data it receives over the course of
its runtime so switching back to older sets is faster than reloading
it from the server, but if this seriously chokes memory, I need to
come up with a new strategy.

Any help is appreciated!

What will happen with things like collision handling or other 
applications wanting to insert into the database in future etc? Do they 
have to ask you to generate them a PK with your
"special actionscript function"? ;)

Why not do something simple like assign a tempid on the client, do the 
all the DB stuff on the server and return a list of 
temp_client_id=server_side_id key/value pairs, then put those values 
back in the xml on the client? Should be simple enough.

At least that way you are not generating database primary keys in your 
client app. You can also implement a strategy on the server side so your 
client app never gets a real database PK.

Roger, I used your suggestion about storing the open module data in 
an array then pulling up the details when I need it for unload or 
other operations. Works great. Thanks again.

Re: [flexcoders] Data Provider refresh problems

[flexcoders] firstTabStyleName?

Does firstTabStyleName work for either the TabNavigator or TabBar?  I see
the style definitions in both classes, but I don't see how and/or if they
are implemented.

Yup. From Flex Builder 2, select Project...Publish Application Source
from the main menu bar. It outputs the source in HTML format and adds
in the link as an attribute to your main MXML's application element.

Hi all,

 

   i'm new to this list, and to flex and flash. I've just posted
my first experiment with flex up on the web and if anyone has time to
examine it and would like to offer any feedback I'd be very grateful. It's a
very simplistic pong game, where you can control the movement of the paddles
up and down by waving your hands in front of the webcam. I wrote it as a
proof of concept, and in doing so tried to learn about the bitmap API and
various things like filters and matrices - making use of the excellent
tutorial by Guy Watson on webcam motion tracking. Code is posted, so if it's
of any use to other noobs like me please feel free, and if anyone can tell
me where I might do things better I'd love to hear from you.

 

cheers,

Toby

Re: [flexcoders] Re: cairngorm strategy question

[slangeberg]

Actually, SoundManager doesn't seem to fit MVC. You have no view and no user
input, correct? Why not just use a Command (or whatever patterns fit)
structure without worrying too much about Cairngorm..? Cairngorm's great and
all, but it is intended to manage large applications with many views, in the
end.

Looking back at your orig. post, looks like Command/Event structure may be
just fine, but that also doesn't mean you need to use the CairngormCommand
(if such exists). maybe what you really want is a state machine that fires
some events (probably). That state machine could very well sit in your model
and fire events. Or not!

You might want to take a look at the concept of CRC's (
http://en.wikipedia.org/wiki/Class-Responsibility-Collaboration_card) as a
starting point. In the end, KISS works!

[flexcoders] Re: Not able to generate GUID

[scott_flex]

Thanks for the reply... i probably will look into writing my own 
implementation.  Never really thought of it...

Generating GUIDs on server, while i can do that, just makes more 
sense if it's done in the flex app itself.

and yes... these IDs will be used as primary keys in my database... 
at least that's the current design i'm thinking about.

I'm generating an XML document in my flex app, where each 
node/element and its attributes represent a single row and child rows 
in a parent child/foreign key relationship.

When i call a web service, i get my xml document which contains pre-
existing primary keys but when i add elements that have not yet had 
been persisted to the database i don't want to both send up my xml 
data and then turn right around and pull it back down just so my new 
xml elements/nodes have the correct primary keys attached.  That's 
especially important when i save/send up the xml a second and third 
time.

If i can assign my IDs earlier in the process, that solves that 
issue.  I still have to check pre-existence on my server side when i 
actually commit my changes to either run an insert or update sql 
statement.

[flexcoders] Limitation of ObjectUtil.copy???

[Dan]

Hi all,

Does anyone try using ObjectUtil.copy and get the fail to convert 
object error?

I use this for some Java external generated class, then it work fine. 
But as I try to copy a class that is construct in AS, then it failed 
and get a runtime fail to convert error. Is there any limitation on 
this? I search some post on web and it mention about externalizable, 
what is that? and is it related?

Thanks guys,

I still dont know what I am going to do, but it is very helpful to
hear the arguments. Sometimes it is really helpful just to get other
peoples views. Obviously this is a bit of a gray area and there is no
*wrong* answer here, which is why nuance and opinion are quite
helpful.

Re: [flexcoders] Not able to generate GUID

scott_flex wrote:
> Is there no function or object to generate a GUID, a true globally 
> unique identifier?

Just write your own--it's dirt simple.  FYI, GUIDs and UUIDs aren't 
actually guaranteed to be absolutely unique--however, given the number 
of random bits involved, a repeat is statistically highly unlikely to 
happen.

They're essentially just concatenated random bits,  although in some 
cases a few bits are derived from MAC addresses (per version 1 UUIDs, 
which you won't have to access to) or hashes of a URL (version 3 and 5 
UUIDs).

See:

   http://en.wikipedia.org/wiki/Globally_Unique_Identifier

   http://www.ietf.org/rfc/rfc4122.txt

If you need it to play with a server and you're worried about repeats 
enough to expend some developer cycles, a better use of your time is to 
hash the GUIDs that you're given on the server-side and do a quick 
search for a collision prior to creating a database entry.  This tactic 
also gets you around the possibility of malicious folk passing in faked 
GUIDs that they know may result in a collision.

[flexcoders] Data Provider refresh problems

[tdexterus]

Hi All
I have a relatively simple template, we are using XML data generated 
and embedded into the template. The template has a combo box that is 
initialized upon opening the template - it has a list of Departments 
+ 'All'. The user can change the combo choice, the XML is filtered 
and a chart and table are refreshed with the same data. 
All is fine except when the user comes back to 'All' ... nothing is 
rendered as if no data is returned. I have debugged and the code is 
returning all XMLdata:
Code snippet
private function getEmployees(deptVal:String):void
{
 if (deptVal == 'All')
 {
 // we want the complete data set again so use empty filter
  EmpTable.dataProvider = dataXML.ROW.(DEPARTMENT_NAME != null);
  deptChart.dataProvider = dataXML.ROW.(DEPARTMENT_NAME != null);
}
 // Combo box selection has been made so filter by Deprtment
 EmpTable.dataProvider = dataXML.ROW.(DEPARTMENT_NAME == 
deptVal);   
deptChart.dataProvider = dataXML.ROW.(DEPARTMENT_NAME == deptVal);
  }

Any ideas why the All option is not refreshing the output, I have 
tried variations on this theme. Is there a method to force a refresh 
of the components ?
Thanks for any help, Tim

[flexcoders] Re: cairngorm strategy question

[JWOpitz]

I should probably clarify a few things.  If you have MVC, and I had to
qualify a SoundManager class as one of those, I would probably see it
first as a command class.  Manager type classes generally are of this
nature anyway.  But that can easily be argued to say Sound is also a
view type nature too and there is enough supporting information to be
so.  Maybe this is more about personal preference as I can see both
sides.  

As to why I don't like the Model doing command-ish like things is that
 again it is not its responsibility.  Now that is not too say that it
can't dispatch events.  In fact when you have a [Bindable] class, it
automatically dispatches propertyChange events.  So that is perfectly
acceptable in my book.  In fact if you look in the flex2 reference
material and search metadata, it explains how this works internally
and how you can do it manually.  I do not, however, like methods in
the Model aside from getters/setters.  

Many of the developers on my team, however do like to stick methods
(not getters/setters) in the model.  I don't like it and advocate
against it.  For instance we have a customizable dataGrid where users
can add various column types with specific data.  I suggested having a
command-type class build columns for it.  However, my teammates wanted
to have a method in the model.  For what reasons I do not now.  All I
know is that although I love democracy in terms of politics, I cannot
stand it in application development. Sorry for that.  Just a rant and
rave for a sec.  Back to the point though, to maintain consistency
with the MVC framework, some sort of ColumnManager would be
appropriate and would be in the command family.  

I am not any kind of MVC purist and occasionaly bend the rules or do
something questionable with regards to what we have been discussing. 
But when developers start deviating dramatically from the core
purposes of what a model is, what a command is, what a view is, then I
will raise an eyebrow and possibly a stink.  

Again my 2 cents.  Hope it helps in your decision making.

Re: [flexcoders] Disable Clicks while on busyCursor

[Anthony Lee]

The obvious solutions would be:

1) Enable/disable a transparent button that's as big as the stage and has
the greatest z depth / lowest childIndex

2) Make all your active components register themselves then loop through and
disable/enable them according to your busy state

I'm sure there are fancier ways to do it but these should get the job done.

Yup.  From Flex Builder 2, select Project...Publish Application Source 
from the main menu bar.  It outputs the source in HTML format and adds

It looks like it doesnt look inside your array for changes, so you need to
do what you just did then create a new array with the source of you ammended
one.

model.downloads.addItem( aNewDownloadVO );
model.downloads = new ArrayCollection( model.downloads.source );

[flexcoders] Trouble passing data between components

[Jack OMelia]

Hi All,

I'm more of a designer than a developer, and as such my coding skills
are not outstanding, so bear with me.

I have an application with custom components inside a viewstack. In one
component I have a datagrid and I would like to have data from the
selected row of the datagrid populate text fields in a separate
viewstack child, and I can't seem to get this to work.

Here is the viewstack (edited to show just the relevant sections):


 
 
 
 
 
 
 
 

 
 
 
 
 
 
 
 
 
 

The datagrid is in the component instantiated in the "ViewAssurance"
viewstack child at , and the
datagrid code is here:

 
 
 
 
 
 
 
 
 
 

If they were part of the same file I would use something like:



but I need a more explicit path between the two. I've tried
"Application.application.viewstackMain..etc,etc," but whatever
combinations I try don't work.

What am I missing here?

Thanks,
Jack

[flexcoders] Re: Keyboard issues on VISTA - Important

[iko_knyphausen]

I think I finally found the problem source...

It seems to be connected to the hosting HTML file (and possibly its JS
code - not sure). That is the file that pulls flash player, checks for
the required version, etc. This file is generated automatically by Flex
and used as default on the web server...

I don't know how this can affect the keyboard input, but after pulling a
lot on my hair over this issue, I swear I am not making this up.

If I start the application by loading the SWF file directly, all
keyboard issues are gone...

Ideas anyone (someone at Adobe maybe?)

[flexcoders] Can I access HTTP session variables in Flex without using Flashvars?

[thegators_2002]

I am able to create a web service request in Flex, using parameters
sent to the html page via a query string which is then passed in using
flashvars.  However, now I am being asked if I can do this without
having a query string for all to see with this information in plain
sight.  The idea is to use session variables to store this info.  It's
just a few items, like an account ID, user ID, a URL for the WSDL
file, and a couple others.

I am not familiar with web sessions or with how that info gets
accessed by Flex, I am more of a desktop developer.  So I ask if this
is a sound strategy, or if there are other, better ways to do this? 
And if there are any good examples available?  

The app has users log in and get authenticated, and we want to pass
that info to the web service.  As it is right now, not authenticating
the user request and passing a couple IDs and a URL in the query
string would allow anybody anywhere to access that web service at any
time.  I need some way to secure it or at least drastically limit the
amount of time it would be valid.

Thank you for any assistance!


Here is my code as of right now:

private var accountID:String;   
private var systemUserID:String;
private var myWebServiceURL:String;

public var MyService:WebService = new mx.rpc.soap.WebService();

// This method runs on start-up.  It pulls in Flashvars from the
parent HTML file, and starts up the web service.
public function initApp():void
{   
accountID = Application.application.parameters.accountID;
systemUserID = Application.application.parameters.systemUserID; 
myWebServiceURL = Application.application.parameters.webServiceURL;

// Call the web service to get an RRM results doc
UseWebService( myWebServiceURL + "?WSDL");
}



// Create a web service and load the WSDL, using ActionScript
public function UseWebService( wsdl:String):void 
{
// Set the path to the WSDL
MyService.wsdl = wsdl;
 
// Set listeners for the result and fault events of the specific web
service method   
   
MyService.GetRRMAnalysisResultsFromAccountIDStr.addEventListener("result",
resultHandler);
   
MyService.GetRRMAnalysisResultsFromAccountIDStr.addEventListener("fault",
faultHandler);  

// Add a listener event for the web service load completion
MyService.addEventListener("load", loadHandler);

// Load the WSDL into the web service
MyService.loadWSDL();
}



// Once the WSDL is loaded into the web service, this handler will
run.  Call the appropriate service and send credentials.
public function loadHandler(event:LoadEvent):void 
{
MyService.GetRRMAnalysisResultsFromAccountIDStr( accountID, systemUserID);
}



// If there is a fault in setting up the web service, this will run. 
It informs the user there was a problem.
public function faultHandler(event:FaultEvent):void 
{
Alert.show("An error occurred while accessing the web service: " +
event.fault.faultString + ".\nPlease close this application.", "Error");
}  



// Event Handler: listens for the web service call to be completed   
private function resultHandler(event:ResultEvent):void 
{   
// Create an XML doc and load it with the XML string returned from the
web service
var myXml:XML = new
XML(MyService.GetRRMAnalysisResultsFromAccountIDStr.lastResult);

// Copy the XML doc to the custom class which will handle extracting 
ResultSet.XmlResults( myXml);
}

Re: [flexcoders] Re: cairngorm strategy question

[Troy Gilbert]

Coming from a game development background, I always consider sound to be
apart of the view. Generally, I consider anything directly consumed by the
user to be "view" while internal state that has meaning independent of the
view is the model.

So, while your sound player does maintain state (the currently playing
sound, the current position in the sound being played), you need to answer
for yourself whether that state is on par with (to use a trivial example)
the contacts in an address book or the position of a scroll bar on a text
box. If the sounds are used to convey information about state, then it
sounds to me they're more like scrollbars. If the sounds *are* your state
that you're concerned with (like an audio editing application), then they
should be in the model.

Another way to judge it: if you were going to persist the current state of
your application to disk, would you worry about persisting the state related
to sound? Or to put it another way: if I was forced to manipulate the data
in your application through an API instead of a UI, do I care about the
sounds or are they only there for the pleasure of the human audience?

I read your blog, and it seems to finish right where I am beginning. I
agree with your premise that commands can and should be used for
internal app communication and not just for remote access. In fact
that is why I posted my question. The issue is where in the cairngorm
architecture a singleton type class of this type should sit. In
cairngorm you have events, commands, delegates, views and model. As I
have spent time thinking about this today, I have started to think
that it is indeed closest to being an element of the model. It retains
state and can be queried as any element of the model can. The only
weird thing is that it can broadcast events. But it makes sense to me
that certain types of model information perhaps should be able to
generate events.

Currently models generate events surreptitiously via the binding
architecture. They really do generate events, just not in the
cairngorm way. So why not allow model elements to generate cairngorm
events?

> I would not start having the model do any command-ish activities since

Why not?

If a model contains data that changes, why is it appropriate that the
only way to "tell the world" is via binding, when binding just doesnt
always match the need?

only way to "tell the world" is via binding, when binding just doesnt
always match the need?

[flexcoders] Re: handling both MOUSE_DOWN and MOUSE_CLICK

[Paul DeCoursey]

There is nothing abnormal about these gestures.  A click is a mouse
press and release, it cannot be without both actions.  

You don't want to mess with timers, just set a var to true on a mouse
down and reset it to false on mouse up and click.  if that var is true
on the mouse move then start drag. you can keep select on click, and
perhaps you need to do something on the start drag like select.

All these gestures work as expected.

> 1. click
Fires the CLICK
> 2. double-click
Fires the DOUBLE_CLICK event
> 3. press and hold (move is optional)
press is the MOUSE_DOWN event, hold isn't an event, it's the lack of
event.
> 4. release
Fires the MOUSE_UP event

try the above strategy and I think you'll find it's what you are
expecting.

[flexcoders] Re: cairngorm strategy question

[JWOpitz]

I am sure there will be plenty of suggestions, but it sounds like you
need some sort of static point of access for your sounds.  There are
few approaches that I would try:

Make a SoundManager Singleton class that extends the EventDispatcher.
 That way if you make use of the basic Flex events, you can then have
the soundManager instance assign its event handlers.

As for using the Cairngorm class, I think that could also be a good
idea.  I have written a little blog on it here:
http://jwopitz.wordpress.com/2007/03/01/

I would not start having the model do any command-ish activities since
that is not its responsibility.  And I would not make it a view-type
since, well, its not a view, its a sound.  

Hope that helps.

[flexcoders] cacheAsBitmap

[Guy Morton]

I've created an mxml component that uses a canvas object and writes a  
graphic on it based on some input parameters. This graphic is then  
animated over a bitmap background. If I set cacheAsBitmap on the  
graphic's canvas to true, then rotate the canvas, am I improving  
performance? Or does the rotate mean flash will throw away the  
previously cached bitmap and make a new one?

Also, does having a drop shadow filter on the parent canvas container  
affect the behaviour of cacheAsBitmap?

[flexcoders] Re: handling both MOUSE_DOWN and MOUSE_CLICK

[Engkee Kwang]

Paul,

Your explanation is correct in why I'm not getting the behavior I 
want. In a way, what I'm looking for is "logical" mouse event 
behavior that more closely corresponds to what I would consider to 
be "normal" user gestures and expectations, namely, the following

1. click
2. double-click
3. press and hold (move is optional)
4. release

Those are the gestures that users learn when using the mouse. Seems 
like those would be desirable events to be able to map to directly 
and not have to do code like... catch mouse down... fire off timer... 
if timer expires before mouse-up, it's a click... otherwise, we are 
pressing-and-holding... so start a drag...

[flexcoders] Re: Can I use Flash Library items in Flex, if so, how?

[Mark]

I started looking over the examples by Jesse and realized he's using 
the symbols as new components to be placed on the stage.  These are 
great examples but before I get too deep I'm wondering if I can use 
these to accomplish what I'm looking to do, which is…

My Flash app that I'm converting into Flex is a Project Management 
tracker.  In one view the PM can look at a "radar view" that plots 
points on a circle (radar graphic).  The center of the circle is 
today's date and the outer most edge is 2 years out.  Each project 
(point in the Library) gets placed on the radar depending on date.   
So I guess what I need to do is similar to Jesse's example but I 
think I need more control in that I need to place the graphic but 
then need to add points from the library.

[flexcoders] Re: handling both MOUSE_DOWN and MOUSE_CLICK

[Paul DeCoursey]

Click isn't going to happen until after mouse up, and if you start a
drag I'd think that would supress any click events.  I'm thinking you
will just want to do the select on the mouse down.  Then trigger the
drag on mouse_move if no mouse_up or Mouse_click has occurred.

RE: [flexcoders] Special characters after end tag of XML document (HTTPService issue)

[Peter Farland]

If you're not using the proxy, then HTTPService is ultimately using 
flash.net.URLLoader to load and receive the data. You could try to take Flex 
out of the equation for a second and try the raw URLLoader API to see if it 
still occurs there.

[flexcoders] Flex Player 9's (Flex 2) Memory Usage - What's Normal?

[jeofmoyster]

So I'm developing what will be a good-sized application, but I'll be
carefully planning for download speed and runtime efficiency through
ModuleLoader, SWFLoader, etc. 

Right now I've barely begun but have finished the ground level for the
Data Retrieval, Normalization and Management (no FDS). The memory
monitor object shows about 40 megabytes of memory being used when the
data comes in, and drops to 24 MB if I leave the app still for a a
couple minutes afterward (I assume that's garbage collection kicking
after the data normalization). 

Flex is one my first forays into needing to worry about things like
memory management, so I'm looking for best practice and a baseline of
what's expected and acceptable. 

1) What's "average" memory load for a Flex application? When do I
start freaking out about using too much memory? 

2) How do I optimize memory management during run time? What's the
best way to encourage good garbage collection? 

Ideally this app will cache the data it receives over the course of
its runtime so switching back to older sets is faster than reloading
it from the server, but if this seriously chokes memory, I need to
come up with a new strategy.

Any help is appreciated!

[flexcoders] httpservice; ie and 2032 error

Hi,
  I am getting a 2032 (stream error )what I first hit my httpservice
using internet explorer. This does not happen with firefox. In either
case I am getting a success response back from the service (status =
200). When I clear the cache on ie, I do not get the error. Only on
the first access. Here is my service:



{someServiceAction}
{deviceIndex}



I am executing via someService.send() which is executed in a method
that is invoked on a module preinitialize. Thanks,

[flexcoders] handling both MOUSE_DOWN and MOUSE_CLICK

[Engkee Kwang]

what is the trick to listen for and handle both MOUSE_CLICK (say to 
select) and MOUSE_DOWN (to start dragging)?

I have a Label on a canvas. First I added a listener on MOUSE_CLICK and 
that works. My handler gets called and I can "select" the item.

Then to support D&D, I added another listener on MOUSE_DOWN. When I do 
that, I get call on mouse-down and I can then initiate the drag. 
Unfortunately, I no longer get called on click.

Presumably, rather than listening for MOUSE_DOWN, what I really need to 
do is listen for the mouse-down but without any mouse-up for some 
interval... so as to distinguish it from a click. Is there such an 
event?

RE: [flexcoders] Special characters after end tag of XML document (HTTPService issue)

[Peter Farland]

Perhaps your special characters trailing the document are whitespace
(tabs, new lines, etc)?
 
There are known issues with constructing an XML instance (the basis for
E4X) from Strings containing whitespace between processing instructions
and the start of the root element (or trailing whitespace after the root
element) and with XML.ignoreWhitespace set to false.
 
Have you by any chance set XML.ignoreWhitespace to false?
 
If so, for your particular scenario of trailing special characters you
could keep HTTPService's resultFormat as "text" to get it as a raw
String, then use mx.utils.StringUtil.trim() on the String, and then
construct a new XML instance from your String new XML(result).

I've got an E4X HTTPService in Flex that is calling a servlet which
returns an XML 
document. Approximately 80% of the time, the servlet works fine and the
HTTPService 
result is a valid XML doc -- the rest of the time, the HTTPService is
giving me a fault:

[RPC Fault faultString="Error #1088: The markup in the document
following the root 
element must be well-formed." faultCode="Client.CouldNotDecode"

After taking a look at the servlet directly in the browser (removing
Flex from the equation), 
I have not noticed any issue with the XML returned and we have run it
through several 
online validation tools. The servlet code that generated the XML is fine
as well, we have 
checked that numerous times.

I thought that the problem might be the resultFormat of the HTTPService
(currently E4X), 
so I changed it to 'text' so I could see if there was any special
characters or issues with the 
XML after Flex called the servlet. I discovered that there are seemingly
random special 
characters being appended to the end of the document (after the end
tag). The string of 
random special characters ranges from 2-10 in length.

Note: I have since put the resultFormat of the HTTPService back to e4x.

Does anybody have any idea why this might be happening? We have observed
this on 
Windows, OS X and Ubuntu Linux platforms, in IE7, Safari, Firefox (Mac)
and Firefox 
(Ubuntu).

Thanks for your help,

RE: [flexcoders] Flex embedding SWF file and using it like a component

[Roger Gonzalez]

You should use the 2.0.1 Modules feature for this, its pretty much
exactly what you want.
 
In any case, whenever you do make a reference to objects within
dynamically loaded code, you should design some interfaces for
communication so that you're not making hard type references to
implementation classes.  There are many design patterns that can provide
a useful scheme design base (the 2.0.1 Modules feature uses the
"factory" pattern to good effect here.)

I'm planning a rather large application that has several
sub-modules
that I thought should be loaded individually as separate swf's
to
decrease load time and memory requirements since the sub-modules
would
never need to be loaded at the same time.

I'm having trouble finding any articles on how to access the swf
from
the swfloader once it's loaded.

I found one blog from Peter Ent:

http://weblogs.macromedia.com/pent/archives/2004/12/accessing_swfs.cfm



but the sample files are not there any more, and it's from 2004
so I'm
not sure if it would work with Flex 2 either...

I'm trying to access the content of the loaded swf throught the
swfloader's content property, but it's not finding the objects
within
the swf because it hasn't been loaded yet, and so the outer mxml
will
not compile without errors.

Does anyone have any sample code that does this, or have a

Re: [flexcoders] Re: Problems with "The E4X approach to XML processing"

[slangeberg]

I think in the docs, these should be returning XMLList, technically. Not
sure if it evals to XML in typeof().

  Hi Allen,

Glad to be of help.

btw ... you wrote:

I did some tests using the ActionScript typeOf() operator and all values
returned from the E4x operators are showing as typeOf XML.

For example, I popped the following into the MXML from my last post:



I did a few more statements than just the one above, and regardless of the

[flexcoders] Special characters after end tag of XML document (HTTPService issue)

[klumikaze]

I've got an E4X HTTPService in Flex that is calling a servlet which returns an 
XML 
document. Approximately 80% of the time, the servlet works fine and the 
HTTPService 
result is a valid XML doc -- the rest of the time, the HTTPService is giving me 
a fault:

[RPC Fault faultString="Error #1088: The markup in the document following the 
root 
element must be well-formed." faultCode="Client.CouldNotDecode" 
faultDetail="null"]

After taking a look at the servlet directly in the browser (removing Flex from 
the equation), 
I have not noticed any issue with the XML returned and we have run it through 
several 
online validation tools. The servlet code that generated the XML is fine as 
well, we have 
checked that numerous times.

I thought that the problem might be the resultFormat of the HTTPService 
(currently E4X), 
so I changed it to 'text' so I could see if there was any special characters or 
issues with the 
XML after Flex called the servlet. I discovered that there are seemingly random 
special 
characters being appended to the end of the document (after the end tag). The 
string of 
random special characters ranges from 2-10 in length.

Note: I have since put the resultFormat of the HTTPService back to e4x.

Does anybody have any idea why this might be happening? We have observed this 
on 
Windows, OS X and Ubuntu Linux platforms, in IE7, Safari, Firefox (Mac) and 
Firefox 
(Ubuntu).

Thanks for your help,

Brian

It appears that the upload code works differently on a linux player.
The exact same code works as advertised on windows/mac players.

I tried getting an update from Adobe, and got the latest player for

Re: [flexcoders] flex bluetooth.

[Chris Allen]

Jim's right. This is way beyond the scope of Flex by itself.

I feel like a broken record because I keep suggesting Red5
(http://osflash.org/red5) on this list, but in this case (like many
others) It could be just what you need. It in this scenario Red5 would
be used as a sort of proxy to do the Bluetooth communication.

There are some Java libraries for bluetooth that you could hook up and
use with Red5. Or you could use JNI to do the communication to a C++
application. Then you could have calls from Flex/Flash sent either
through RTMP or remoting then get broadcasted to your Bluetooth device
via this Java API.

There's also a book on the subject of using Bluetooth with Java:
http://www.amazon.com/Bluetooth-Java-Bruce-Hopkins/dp/1590590783

I certainly think that it would be a pretty cool and novel way of
using these technologies. I would love to hear more about it if you
have some success getting this to work.

I hope this helps and good luck.

RE: [flexcoders] Re: Managing Multiple Modules

[Roger Gonzalez]

The module manager knows what modules have been loaded, but it doesn't
provide an iterator.
 
If you know the URLs, you can check a given module's load status.  It is
harmless (other than creating some cached state) to probe a given URL
before you call "load".
 
Removing the tab (and ensuring that you have no other references to the
child control) will only cause instance data to be GC'ed, not the
underlying bytecode.
 
The module's code will never get fully recycled unless you call
"unload", because there is a ModuleInfo reference handing onto its
internal module class factory (in case there is a subsequent need to
reuse it).

Does the module factory hold information (module ID, URL etc...)

How important is it to unload modules? If I remove a specific

Allow you to view the source by Right-Click -> View Source. As I saw

[flexcoders] Flex embedding SWF file and using it like a component

[jack_freud]

I'm planning a rather large application that has several sub-modules
that I thought should be loaded individually as separate swf's to
decrease load time and memory requirements since the sub-modules would
never need to be loaded at the same time.

I'm having trouble finding any articles on how to access the swf from
the swfloader once it's loaded.

I found one blog from Peter Ent:
http://weblogs.macromedia.com/pent/archives/2004/12/accessing_swfs.cfm

but the sample files are not there any more, and it's from 2004 so I'm
not sure if it would work with Flex 2 either...

I'm trying to access the content of the loaded swf throught the
swfloader's content property, but it's not finding the objects within
the swf because it hasn't been loaded yet, and so the outer mxml will
not compile without errors.

Does anyone have any sample code that does this, or have a suggestion
as to whether this is a good design idea or not - I'm afraid of
loading a Flex app with hundreds of screens and having it take forever
to load.

Thanks!

RE: [flexcoders] Re: Populate ComboBox from database - NOT using Flex Data Services

[Piotrowski, John]

Are you sure the data is coming back from the remote object properly and
it is in the right format?  I would try to set a breakpoint private
function getJobResult(event:Object):void and then look at the event
object in the debugger.  

 

Also try replacing the getJobResult with

 

private function getJobResult(event:Object):void{
jobs = event.result["RESULTS"] as ArrayCollection;
}



 

and move the Bindable jobs... to the top right after the import
statements.

 

You have a databinding to the variable jobs and this is bound to the
comboBox, so the result of the remoteobject should update this bound
jobs variable and then it will update the combobox automatically.

[flexcoders] Re: printJob on a textArea

[scott_flex]

Try removing the height from your text area object and just let flex 
determine the height automatically... ie, it doesn't have scroll bars 
itself.  Then print it, you should get it all.

You'll probably also want to set the width manually when you print it 
to the width of the print object...  Flex prints at 72 dpi... so 8.5 X 
11 paper is 612 pixels wide, assuming you are not counting for any 
margins.

It appears flex will just print exactly what's on screen, scroll bars 
and all and it's not intelligent for printing text.  So in my case, i 
transform the objects and put them in a better printing state before I 
send them tothe printer... because the format for printing is not 
always desired for how it shows on screen.

I wish flex had better printing utilities for page breaks and making it 
easier to put more than one display object on a single page... but then 
again, you have a lot more control than trying to generate a html and 
print a web page... IF you want complete control over how things are 
printed.

[flexcoders] Re: FileReference.upload, URLVariables,uploadDataFieldName not working as expect

[w4kpm]

Ben,

My server side is simply a django procedure that dumps the post call
giving the output that I listed in the last post.


def importCsvFile(request):

print "made it in"

print request.raw_post_data


I *know* that I can re-name it on my end, but it really bugs me when I
do what the docs say and it doesn't do what is expected., I followed
the docs, and it's not working, so I'm trying to figure out what is wrong.

If I figure out what it is, I'll post back here, just thinking someone
else had run across this before.


The main issue that I need to solve is that I need to send other
variables back with the file in the post. That doesn't appear to be
happening.

Thanks,

Kelly

RE: [flexcoders] Managing Multiple Modules

[Roger Gonzalez]

The URL for a given module is a unique key for the module at that URL,
no matter how many times you get it.  Each time you get a ModuleInfo,
you can use it to request an unload.  (Note that unload just makes
things available for GC, it does not force things to unload.)
 
There's no reason why you need to always put the module info into a
single variable though, of course its going to get overridden.  You
could always keep an array of module infos.  Or, you can just call
getModule again.  No big deal.

Hello, I am trying to create an application that has a tab
navigator 
that gets loaded with different modules, similar to a browser
window 
opening multiple tabs. I have tried different methods but do not
know 
how to get a reference to a module to unload it once multiple
modules 
have been loaded. This is the code I am using to load the
modules:

public var info:IModuleInfo;

private function LoadModule(strUrl:String):void
{
info = ModuleManager.getModule(strUrl);

info.addEventListener(ModuleEvent.READY, modEventHandler);
info.load();
}
private function modEventHandler(e:ModuleEvent):void 
{
var m:Module = info.factory.create() as Module;
myTabs.addChild(m);
}

This code works very well to load as many modules as I need. The

problem is the public var info gets updated as each new module
get 
loaded. So I do I get an IModuleInfo object for a module that
has 
already been loaded that I can then call the unload() method.
Please 
any help or suggestions would be greatly appreciated. Thanks

[flexcoders] cairngorm strategy question

[hank williams]

I have a class that is basically a sound server. It both generates
events - like "sound #1234 is finished" and receives commands like
"start playing sound #4567".

My problem is that I am not sure where to put this in the cairngorm universe.

If I were to put it in the model, thats kinda wierd since it generates
events, and models dont ususally generate cairngorm events. One
thought I had was not to have it generate events, but to use binding
to get information out of the object, but events really are better
since it may be playing multiple sounds and events allow me to specify
that multiple things are happening. Binding would be less clean
because my binding subscribers would have to bind to an array since
any number of sounds may be in play at one time.

If I were to make the class a view, thats wierd because views dont
generally get modified by cairngorm events.

Of course the third way is just to use standard AS3 events - which is
the way it currently works - but the architecture of commands in
cairngorm is so clean with a class for each command that it makes it
really easy to read the code.  So if I can, I would like to use the
cairngorm command structure for this piece if I can make it work.

Any thoughts greatly appreciated.

Hi All,

I am developing a flex app, for the first time. I have three main
components. A combo-box, datagrid and a graph. The combobox is
populated using httprequest to a php page which provides data from
mysql database. My problem is I need to populate the datagrid and
update graph depending on the value selected from combo-box but can't
seem to get it working. I have tried states and also went to the
extent of replacing the whole datgrid with another one (visible
property) but still stuck. I can send the code as soon as my
workstation comes up, but if someone has any pointer he/she can spare
me, it will be greatly appriciated.

thanks in advance

RE: [flexcoders] Simple form submit example

[Tracy Spratt]

A Flex "form" is just a layout container.  There is no built-in "submit"
functionality.  There is no "submit button".

 

You will need to use one of the RPC data services to send your data to
the server.

 

Also be aware that two-way binding is not automatic.  Modifying a form
field does not automatically update the dataProvider.  You will need to
set this up if you want it.

What I need is what gets the two talking?

I'm not using FDS at this point. Just ColdFusion MX7.02.

I assume I should use a remoteobject, but I don't know how to pass 
the flex form data to it when the user click submit.

What goes in the onclick on the submit button?
What AS do I need to pass the form data to the remoteobject?
What should the remoteobject look like to pass the data to the CFC?

I'm just learning flex, but I'm used to ColdFusion flash forms using 
cfinvoke arguments. I assume it is done using remoteobject instead 
of cfinvoke. But I'm open to the easiest way to do it.

"How do I save an xml file to the server?"  Flex's back-end agnosticism
always poses a challenge for Flex developers that need to retrieve/save
data, but do not have team of developers behind them to help.

 

I wrote an example that retrieves an xml file from the server, allows
you to edit it, and then save it back.  It includes two backend platform
examples, asp.net, and jsp.  A similar tutorial using php, of cf, or
anything would be helpful.

 

Actually, the xml editor part of my example may make the example too
complex for many, and maybe should be a separate example.  If I do it
over, I will make the save/retrieve functionality the focus.

Re: [flexcoders] How Can I save the drawing made at runtime

[Troy Gilbert]

Tom's suggestion is a decent one if you're looking to save the image in an
editable form. If you're wanting to save the image as a GIF/JPG/PNG/etc.,
then you should search around for the various PNG enconders (I believe
Adobe's ascorelib has at least a JPG encoder, maybe a few other formats as
well). To turn your shapes into a bitmap, you'll need to use the Bitmap API,
in particular BitmapData.draw() to draw the DisplayObjectContainer that
serves as the shapes' root (a Canvas or other UIComponent most likely) to a
bitmap, use the ascorelib/etc. methods to turn that into a ByteArray of JPG
data, then send that to the server which will roundtrip back to the user as
a downloadable file (since Flex can't directly save a file to the user's
machine).

The critical piece here is to drive the state(selected=true/false) of

required because the list controls re-use the renderers whne the list is

Re: [flexcoders] Re: Problems with "The E4X approach to XML processing"

[Troy Gilbert]

This same problem tripped me up as well... I couldn't figure out why I kept
getting XMLList's that contained elements when I was *sure* that the
elements shouldn't be there. I was checking for "list.length > != 0" which
of course was always true as ".length" was undefined for my XML elements.

What I realized (and already knew but just wasn't thinking) was that XML and
XMLList don't have any properties... everything is a method. It does that to
avoid colliding with your own element names. So, whenever you're wanting to
access any "property" of an XML node or XMLList don't forget your parens!

when you say 'some data' on the component, do you

 Having your item renderers access  data from your

the system.  If it's a brand new app, the client needs help thinking
about interaction paths, and there's great value in putting in a
little extra thought ahead of time to help you flesh out what might be
possible in the time period given.  (I don't know about you, but my
clients always want the sun, moon, and the stars, and they want it
now- and it becomes my job to tell them how long things will take and
help them make a decision about what they want within the allocated time)

I've always found that when I am looking at a (potential) project, I
already know (or find out very soon) what the overarching business
functions are.  This allows me to build a very simple setup to allow
for this rapid prototyping.  (Remember that Cairngorm is a
micro-architecture, not just a framework).  It really only takes a few
hours to set up simple events and once you have one set up, the others
follow the same, or a very similar pattern.

Re: [flexcoders] Flex Builder Syntax Highlighting Not Working

It works on some files and others it doesn't.  What syntax causes it to
fail?

[flexcoders] Re: Populate ComboBox from database - NOT using Flex Data Services

[April]

Thank you for everyone's responses, but I'm still not having any luck.  I'm not 
getting any 
errors - but my combobox is not populating.  Again, I'm really new to Flex.

My app is called PreTraffic with the following structure:

PreTraffic
 cfc (folder)
  job.cfc
 JobSearch.cfc

**

job.cfc contatins:









SELECT  job_id, job_title
FROMjob
WHERE   status = 'O'
ORDER BYjob_title


SELECT  job_title AS label, job_id AS data
FROMjob
ORDER BYlabel


   


**

JobSearch.mxml contains:


http://www.adobe.com/2006/mxml"; 
xmlns="*"
layout="absolute" 
backgroundGradientColors="[#ff, #d0d0d0]"
creationComplete="InitApp()">









 

RE: [flexcoders] Re: ctrl key with a combination - doesnt seem to work

[Robert Chyko]

Did a little further testing... if I use Firefox when I am debugging I
get 2 KeyBoard events that are captured.  The second event has the
correct keyCode that I am looking for (67).
 
If I debug using IE, only one event ever gets handled, its keyCode is
17.  So I guess the question becomes, is Flash Player dropping the
second event, or is IE blocking it?

I am having the same problem.  At least from where I am standing
there doesn't appear to be a way to capture the second key.  I also get
true for the value of event.ctrlKey and 17 for event.keyCode.
 
Anyone have any insight?

Hi Adam,

That was a typo. Here's what I have :

public function myKeyDown(event:KeyboardEvent):void {

}

And I have specified the event listener in the DG as 


The problem is not with the Event generation. I have put
trace and it
seems to call the function when the event occurs. The
problem is
detecting the CTRL + .

The keyCode always returns 17 (for CTRL key) and the
ctrlKey is TRUE.
What happens to the keyCode of the other key , for Ex: C
or c which
would be 67 or 99 ???

Is there any other way of detecting it, which I am not
aware or is
this a Flex bug ? It does not work as suggestec in the
Flex help docs.

[flexcoders] Re: Flex Prototyping Best Practices

[akhilbhaskar]

Well, yes and no.  You're right about finding the balance part.  Since
you're in the agile world, it really is dependent on your experience
and whether or not you are a partner in the design, or just the
implementor.

If you find that you don't have time to get things set up beforehand,
you always have the option of fleshing out the UI with the client,
then telling them that you'd have some sample data fleshed out for
them for the next day (or more depending on number of
screens/complexity, etc.)

Architecting an app is IMHO a different paradigm from how it looks and
feels.  If the app is being built to replace an existing application,
there's already a model for how the client is used to interacting with
the system.  If it's a brand new app, the client needs help thinking
about interaction paths, and there's great value in putting in a
little extra thought ahead of time to help you flesh out what might be
possible in the time period given.  (I don't know about you, but my
clients always want the sun, moon, and the stars, and they want it
now- and it becomes my job to tell them how long things will take and
help them make a decision about what they want within the allocated time)

I've always found that when I am looking at a (potential) project, I
already know (or find out very soon) what the overarching business
functions are.  This allows me to build a very simple setup to allow
for this rapid prototyping.  (Remember that Cairngorm is a
micro-architecture, not just a framework).  It really only takes a few
hours to set up simple events and once you have one set up, the others
follow the same, or a very similar pattern.
