[flexcoders] Re: Memory consumption by the browser

[Dmitri Girski]

Ryan, 

Well, it is a big popup, based on a customised Panel component, with 3
states, declared in MXML. All elements are bound to the single data
structure which is passed as the parameter at the init stage.

I am using my own caching PopUpManager, which tries to find the object
in the dictionary before using createPopUp() method.

I know about the weak reference parameter in the event subscription,
but this is not a case - this panel uses  mxml bindings, i.e.
click="fClickedThat()". 

As I said, I ran it under profiler and every time
PopUpManager.addPopup() makes it visible I can see that the only thing
which is growing in numbers of instances are childConstraintInfo
objects (256 instances per each call). When I hide the panel using
removePopup() - the number of childConstraintInstances does not
decrease. But if I click on the GC button - it goes back to 256
instances (the panel still exists).
I am 100% sure that none of our custom objects are being created
during the process of popup creation.

Of course Profiler  does not show all the objects (I use standard
filter on flash.*), but if I turn it off, Profiler just dies on the
4Gb Quad-core machine. And I am unable to turn on the allocation trace
by the same reason - it just kills JVM. 

So we have to find a workaround for this problem. Simplification of
the panel is not an option so far - for complex tasks you have to use
complex tools, hammer & axe are not always the ultimate answer :)

PS I know that we already reached some limits in our project which are
unknown probably to 99% of developers and most sadly unknown to the
Flex Team.

Here is the example:
http://bugs.adobe.com/jira/browse/FB-12492
This popup window has too many mxml entries (due to the states), so it
takes more than 90 seconds to compare it with the previous revision. I
guess that, if people were creating complex interfaces in enterprise
environment, there will be a lot of fuss around this stupid Java
compare tool.

We also have 4 SWC objects embedded in that panel (graphical
components like buttons or icons developed in Flash). And the Flex
Builder does not like it either - it displays the SWC objects in
Design View only sometimes depending on its own mood and wind
direction. I am unable even to submit a bug on it, as all our small
test cases work fine, the problems appear only in the project environment.


Cheers,
Dmitri.

RE: [flexcoders] DataGrid updateComplete causes lots of memory leak.

[Alex Harui]

You can look at the allocation stack trace to see where those come from.  
WeakMethodClosures can generate false-postives in the profiler so it may just 
be a false alarm.  I don't know why you would need to hook UI or input events 
directly to do vertical scroll positioning.  The secondary view should pull its 
viewstate from a central data model, then you don't need to push information 
into the view and worry about when it is ready.

Selection is fine, as you said, can be done easily.
But I do need UI and event framework for the vertical scroll positioning.

On the other hand, from the profiler, here I do have some interesting
figures:

Memory Snapshot(in couple of minutes interval)
Loitering Objects

WeakMethodClosure | flash.events | Instances:48914(98.43%) |
Memory:782624(83.87%) //with updateComplete

WeakMethodClosure | flash.events | Instances:2(2.25%) | Memory:32(0.23%)
//without updateComplete

Same steps being followed for two parallel instances of same app run and it
returned me above noticeable figures. A couple more lines were there(with
more objects), but this one is noticeable.

RE: [flexcoders] DataGrid updateComplete causes lots of memory leak.

[Alex Harui]

It occurs to me that if you're changing the display in updateComplete you could 
be causing another updateComplete and looping forever.  Set a breakpoint on 
your handler and see how often it gets called.

If I were doing something like this, I'd have a "currentSelection" property 
somewhere that the first DG sets and the second DG reacts to by binding to it 
and avoid using UI and validation events directly.

RE: [flexcoders] DataGrid updateComplete causes lots of memory leak.

[Alex Harui]

Hopefully your code is:
updateComplete=this.callLater(setVerticalScrollBarMethod);

Depending on what that code does, it might use a bunch of memory, but if it 
gets freed later, it isn't a leak.  The profiler will help you determine if 
there really is a leak.

Hi Guyz,
I have a viewstack holding two DG's. When I double click on an item in first
DG, it should switch to the second DG and select the corresponding item in
that DG and scroll down to that item.

If I set verticalscrollbarposition something like..
updateComplete=this.callLater(setVerticalScrollBarMethod());

It causes a lot of memory leak until unless it is switched to the final
view(2nd DG with highlighted item.)
Can anyone tell me what I can use as an alternative to updateComplete ??

[flexcoders] PrintAdvancedDataGrid

[lehaianh1986]

I wonder that PrintAdvancedDataGrid have bug. I have an AIR app to
work with document file. The output is AdvancedDataGrid and I want to
print it.
I use code to work with AdvancedDataGrid follow link
http://livedocs.adobe.com/flex/3/html/help.html?content=printing_5.html#145939

When I debug my app by run only each code line, it can print my table
but not stable, sometimes ok and sometimes print nothing. When I run

[flexcoders] DataGrid updateComplete causes lots of memory leak.

[Manu Dhanda]

Hi Guyz,
I have a viewstack holding two DG's. When I double click on an item in first
DG, it should switch to the second DG and select the corresponding item in
that DG and scroll down to that item.

If I set verticalscrollbarposition something like.. 
updateComplete=this.callLater(setVerticalScrollBarMethod());

It causes a lot of memory leak until unless it is switched to the final
view(2nd DG with highlighted item.)
Can anyone tell me what I can use as an alternative to updateComplete ??

-Manu.

Set your Application width and height to 100%.  Then, when javaScript 
resizes the Object and/or Embed tag (NOT the document), then the 
Application will resize itself appropriately.

You may want to do some basic experimentation and/or research on 
DHTML.  That's beyond the scope of this forum.

RE: [flexcoders] Re: LCDS : Managed associations - creating/deleting new Items

[Jeff Vroom]

Yeah, that 'undefined' error is really just the player incorrectly reporting 
some error which is thrown up on the stack.If you do not register a fault 
handler, it is thrown as an error so that makes sense.

You have autoCommit set to true so the client is committing after each property 
change event which causes a large number of updates.   You probably want to 
just set autoCommit to false and manually call "commit" after each change.
If calling commit is not desired, maybe you just set up a timer to call commit 
periodically if there are any pending changes.

RE: [flexcoders] Re: Memory consumption by the browser

[Ryan Graham]

Hmm... at this point I suppose it depends on what you are doing with
your popup component. We'd have to see some code to try and pinpoint
memory-leaks.

 

Are you creating a new popup everytime the user requests it, or do you
create one instance and use the popup manager to show and hide that
instance, setting data properties accordingly? Are you adding listeners
to descendant components in the popup? If so are you using weak
references? For example:

 

addEventListener(MouseEvent.CLICK, onClick, false, 0, true);

 

and not

 

addEventListener(MouseEvent.CLICK, onClick)

 

HTH,

Ryan

RE: [flexcoders] Is there any difference between BigDecimal in LCDS and FDS

[Jeff Vroom]

Yes, this was just a change to the code I think around the LCDS 2.6 timeframe 
(the release we split BlazeDS off from LCDS).   Keep in mind that BlazeDS is 
just part of LCDS so LCDS will behave that way too in 2.6 and beyond.   I think 
there might even have been a hotfix for the change for 2.5.1 but could be wrong 
about that.

Unfortunately there is still no ActionScript equivalent of BigDecimal.

Hi Flexcoders,

The conversion from Number to BigDecimal in FDS and LCDS seems to be
difference.

In FDS, if VOs mapping is Number to BigDecimal, seems the value is
first convert to Java Double, and then a casting of Double to
BigDecimal, which may cause inaccurate result.

However in LCDS, the value is convert to String and then Cast to
BigDecimal. I am not 100% sure, but the BlazeDS seems doing that, does
the LCDS do the same? Anyone has any idea?

Moreover, is there any class in Flex 3 or even 4 that is similar
BigDecimal which is so essential for finanical application?

I was wondering if you could help me.

I would like to run a download and potentially untrusted Module
(written as a Felx SWF,  ) into an AIR application. This
would be a bit like Tour de Flex, but downloading and storing the
modules locally rather than loading them from a remote server every time.

There are the problems I have faced:

- Not being able to load then as normal because they are not in the
application directory, and also not being able to move them there at
runtime.

- Loading them via a ByteArray, but being unable to then put them in a
sandbox, or restrict their ability using a parentSandboxBridge.

- Getting the well documented "SWF is not a loadable module"
(http://www.mail-archive.com/flexcoders@yahoogroups.com/msg82210.html)

- Not being able to reference loaderInfo.parentSandboxBridge in my
module (should I get the rest working) as parentSandboxBridge is in
the AIR framework, but I need to create a SWF to load in as a module.

If you could help me with any of these point I would really appreciate
it, I will also be happy to document the solution if found.

Thanks

Your version of Flex may not allow a list of fontFamilies.

How much lighter is the background?  Do you have filters applied, alpha?  I've

In my Flex 3 app, when I use an embedded font, I notice that some of my labels 
appear against a backgroundColor that is lighter than the surrounding 
backgroundColor (sometimes, in repeatable conditions), even though this is 
nowhere specified explictly.

If I use a system font like '_sans' this does not happen.

Can anyone explain why this would be, or how I can fix this behavior?

My css code:

@font-face {

src: url('/assets/fonts/MyriadWebPro/MyriadWebPro.ttf');

fontFamily: myriadWebPro;

advancedAntiAliasing: true;

}

global {

fontFamily: myriadWebPro;

fontSize: 12;

border: 1px;

borderStyle: solid;

advancedAntiAliasing: true;

color: white;

}

I also observe that if I say
fontFamily: myriadWebPro,

it loads the myriadWebPro font, but if I say
fontFamily: myriadWebPro, '_sans',

it will load a default serif font instead.  That seems very strange.

Re: [flexcoders] Re: [SebCoverFlow] Enablinghand cursor when user mouse overs an item/picture?

[Fotis Chatzinikos]

Thanks Steve,

I had already tried doing this in the SebCoverFlow.as in the add cover
method, but shape was null there...

Then, after your post, I realized that because init is called, it does not
mean that the shape is initialized and i tried your suggestion

but again ... you were right saying : "seems to go somewhat towards..."
as the hand cursor behavior is at least non-deterministic...
It works... whenever it feels like it...

In My case :when the coverflow is initialized there are not hand cursors,
then after a couple of clicks the cursor appears
but it works as it should only for a couple of clicks...

Maybe there is a problem with the implementation of Away3D's useHandCursor?

Who knows...

I am still trying to get to a solution, i will post here if i get anywhere

Thanks again,
Fotis

Subject: [flexcoders] Mouse click & drop


I'm developing an app with click and drop as opposed to drag and drop.
I have a bunch of images on a canvas. When I click an image it adds a
MOUSE_MOVE event listener to the canvas. I then relocate the image
based on the canvas mouseX and mouseY movement. This event is removed
when I click the mouse a second time. As you can understand, this work
well if the image stays under the mouse, but goes haywire when the
mouse is moved over other images or if you move the mouse too quickly.
I could disable all the other objects on the canvas from responding to
the mouse movement but is there a better way to go about this.

[florian.salihovic]

To give some more input: the error occours when the data is manipulated in an 
itemrenderer of an advanced datagrid which displays items of an filtered 
ArrayCollection.

But what confuses me is, that the constant is null via it is passed, not the 
object.

[flexcoders] Public constant fields are null?

[florian.salihovic]

I'm more then confused! I declare in a class some string constants:

// MyConstants.as
package {
public class MyConstants {
public static const My_CONST:String = "myConst";
}
}

In one of my classes i declare a setter, which makes sure only allowed values 
can be 
processed, otherwise the class will throw an error.

// MyClass.as
package {
public class MyClass {
public function set property(value:String):void
if (value != MyConstants.My_CONST)
throw new Error("Ivnalid value passed: " + value);
}
}

Now it turns out, that sometimes - in a nondeterministic behaviour - null is 
passed 
allthough i pass the constant. How can this be? It can't be a race condition 
since the fields 
should be instantiated at compile time and the can't be null...

Any help? What am i missing? It would really be appreciated!

Reduce the variables, establish functionality one step at a time,

Step 1: Write javascript to resize what you want.  Don't do anything

You need to be resizing the object/embed tag, not telling Flex to 
resize the Application object, so Flex doesn't need to be involved in 
the process, unless you want to be able to click a button to initiate 
the resize. But all that needs to do is just call a js function, which 
should be able to handle it without any info from Flex.

 

[flexcoders] Is there any difference between BigDecimal in LCDS and FDS

[Dan]

Hi Flexcoders,

The conversion from Number to BigDecimal in FDS and LCDS seems to be 
difference. 

In FDS, if VOs mapping is Number to BigDecimal, seems the value is 
first convert to Java Double, and then a casting of Double to 
BigDecimal, which may cause inaccurate result.

However in LCDS, the value is convert to String and then Cast to 
BigDecimal. I am not 100% sure, but the BlazeDS seems doing that, does 
the LCDS do the same? Anyone has any idea?

Moreover, is there any class in Flex 3 or even 4 that is similar 
BigDecimal which is so essential for finanical application?

RE: [flexcoders] Making the impossible possible, something odd is happening

[Gordon Smith]

It's just pointless and possibly inefficient. If a var b is typed as Boolean, 
it is guaranteed to be either true or false, so you might as well just write

if (b)

rather than

if (b == true)

I haven't looked at the bytecode generated in the two cases, but I wouldn't be 
surprised if the latter case generated bytecode for the pointless comparison.

[flexcoders] DataGrid - variableRowHeight="true" and wordWrap="true" not resizing properly

[patrickfkellogg]

I have a problem with  that uses dynamically generated
columns.  When the cell has many characters the row resizes its height
properly with word wrap to show all the cell's contents.  But the next
time the  is shown when there is no data the row height
remains at the previous tall size.  It doesn't resize back down.  I
remember the fix for this before was to place the wordWrap="true" in
the  tag not in the  tag, but this is not an
option since I am creating my columns dynamically.  anyone seen this?
 Any fix?  thanks.

Date: Mon, 09 Feb 2009 14:53:24 -

We faced a similar problem where I'm working, everyone had to
implement a filtering mechanism using user input, including some
special characters. While we were comparing solutions it was noted
that all but mine had troubles with the special characters.I was
just using indexOf(string)>-1 rather than the RegExp methods. Now,
they kind of had me beat when we had to make it case-insensitive, they
only had to add the "i" second parameter whereas I had to upper or
lower case everything, so I had to type more characters there, but it
was still way less than the escaping code they had to add. 
I guess long story short is, take a look at all of the tools in the
box, and make sure you're using the right one for your use-case.

No, I think that they wouldn't use ExternalInterface--that is strictly

you'd manipulate the dom of the embedded HTML document.

Subject: [flexcoders] Tree with Custom itemRenderer "Blocking"
dropIndicator...

 

Hi everyone, I'm not sure how I managed to get to this but here goes

basically here's the problem.

I have a tree that's been extended with a custom itemrenderer. I
actually set the default icon and label to be effectively invisible
and placed an itemrenderer (a hbox with other elements in it) over it. 

I've also added code to the tree such that when you drag a node over a
tree, it will open the tree after 1/2 second (aka spring loaded
folders). This way the user can just rearrange stuff to his/her
hearts content. 

I'm trying to mess around with the showdropfeedback and dropindicator
skin settings. I understand the theory behind it but I am finding a
weird error...

say when I grab a node and mouseover a branch, it'll open the branch
and list its children. The drop indicator works fine until the branch
opens and as I'm scrolling down the open children, the indicator
sometimes disappears... after some investigation, it seems like the
children are being created ON TOP of the indicator, which of course
makes it disappear. If I put a opaque background on the itemrenderer,
it'll definitely make the drop indicator disappear (since it'll be
behind the renderer)

is there a way to FORCE the indicator to be rendered on TOP of
everything? I want to provide user feedback on where the item will
drop... I thought about overriding showDrop feedback and creating a
BRAND NEW hbox or label or something and having the application add
that to its childlist, passing it the coordinates so it'll be placed
on top of the tree... but I'd love an easier solution...

[flexcoders] Re: navigateToURL and "_self" - Works locally, not when swf is on remote server

[uclamerrick]

Thank you for helping.

What I meant was that when I click the image nothing happens.

Also, I was not clear with the local vs remote - my swf file can be
embedded much like youtube, vimeo etc... 

When the swf file is generated from the code below and still on my
laptop clicking the image takes me to the desired URL. 

But then pretend I work at Youtube, and when I export the swf to a
youtube server and someone else embeds the swf file on a page on
xyzdomain.com, clicking the image does not work.

I tried switching this to a button to make sure it was not an image
thing, I got the same result.

The results I describe were on Firefox and Safari on a mac, I have to
install windows on a virtual machine to test that.

RE: [flexcoders] Webservice with Dynamic request?

[Tracy Spratt]

What are the input parameters of the operation "SearchParams"?  What
data types?  Does it have a single argument of type array that that
contains an array  of "searchcriteria" objects, which have the three
search specification values? 

 

The request object is a dynamic "Object", not xml. build it something
like this:

Var oRequest:Object = new Object();

oRequest.criterialist = buildSearchCriteriaArray()

webService.SearchParams.request = oRequest;

 

Be sure to remove the declarative mx:request tag.

Flex from the Source (from Adobe Press) is a really good one to get

book "basic" or easy, you'll do fine on the Flex portion. Or you can 
try the online Flex training 
(http://www.adobe.com/devnet/flex/learn/designer/learningpath.html).
Then, make sure to study AIR - the main areas you should focus on are 
the differences between Flex & AIR (like the file system stuff, HTML, 
etc. - things you can do in an AIR app you can't do in a web app).
Get those 2 things - and you should be good to go. That's what I 
did - of course it DOES help significantly if you are a full time 
Flex developer... But if you can't do that, there's really enough

RE: [flexcoders] Memory consumption by the browser

[Ryan Graham]

Is this in all browsers? I know IE 6 (maybe even 7?) has issues with
memory management. I consistently see memory leak-like behavior with IE
6, for example: 

 

Start debug session for basic app - IE reports 60+ MB memory usage with
a value that steadily climbs as I use the app.

Minimize the browser, then bring it back to view - IE memory usage drops
to ~13 MB.

Use the app for a few more minutes, memory footprint grows in size a few
MB.

Minimize, then restore - IE footprint back down to ~13 MB or so.

 

I don't see the same behavior in FF, which is good. The issue might be
with memory management within that particular browser, and not the Flash
Player.

Subject: [flexcoders] Memory consumption by the browser

 

Hi everybody,

I am trying to solve the problem when my application consumes a lot of
memory.
When application starts in the browser, Windows/Mac reports the size
of browser process around 150Mb.
Then, if you start opening/closing the same popup window (which is
actually being cached by application), the browser starts to grow. 
Each appearance of popup consumes around 1.5Mb [sic!] (the consumer is
childConstraintInfo, around 256 instances)
When you close the pop up, memory sometimes goes down, but never to
the original value. Never ever. At least 100-200kb more at a time.

OK, when I use a profiler, it shows that application consumes 42Mb. 
Profiler shows no leaks, even if the number of instances are growing,
when I click on GarbageCollector icon it always goes to the original
figures, including childConstraintInfo instances. Total Memory stays
at 42Mb mark. Good.
But the problem is that browser's footprint is still growing. After a
couple of hours of work with application it grows to 500-600Mb.

In profiler everything looks perfect. In reality - 600Mb app on 1Gb
system makes it dead.

The question is, what makes browser to be so memory hungry? Why it
consumes more & more memory without any attempt to release it? 

The simplest action with panel instance addPopUp/removePopUp consumes
1.5Mb of memory - I don't believe it. Well, the panels has 3 states
and complex layout with ~100 elements. But what makes it so different
to the "Hello, World" popup, which seems to be right?

Thank you for any thought in advance.

Regards,
Dmitri.

 However, if you're "myfile.as" is an actual class definition, as

 Additionally, how do you define "Whole Path?"  I've always used a

Debug it.  Does pizza_ckb.data contain what you expect?  Is you filter
function working correctly?

Subject: [flexcoders] filter arraycollection with checkbox acting wired

 

hi i am trying to filter an array collection using a checkbox, but
when i select the check box all the data disappears. here is my filter
function

private var pizzaSelected:Boolean;

private function pizzaFilter():void {
if (pizza_ckb.selected == true)
pizzaSelected = pizza_ckb.data;
filterGrid();
pizzaAr.refresh(); 
}

private function filterGrid() :void
{
pizzaAr.filterFunction=myFilterFunction;
pizzaAr.refresh();
}

private function myFilterFunction(item:Object): Boolean
{
return 
(item.pizza == pizzaSelected) ;
}

then on my pizza_ckb checkbox on the click event i call 
pizzaFilter(); is there something am doing wrong. if there is pizza
then the result is true and pizza records show if false nothing is
supposed to show up.

SWF, HTML file etc on the remote server.

What do you mean when you say "does not work"? Do you get an error

You click the image and nothing happens? Something else?

I changed the following and it looks good:

Panel height from 800 to 700
Panel width from 550 to 600
Accordion height from 770 to 650
Form 1 height from 640 to 600
Form 2 height from 640 to 600
Form 3 height from 660 to 600
Form 4 height from 640 to 600

Also changed checkbox id "QuoteForm" to "aQuoteForm" so it would compile.

Re: [flexcoders] Re: how to call javascript functions in AIR application?

[Jeffry Houser]

I thought [but haven't tried] that if you load web pages using the HTML 
browser portion of AIR, it would support embedded SWFs, in which case I 
would expect that the Flash Player JavaScript calls to access the HTML 
wrapper would work. 


[did I mention I haven't tried this?]

However, if you're just trying to convert a Flex built SWF to something 
that can be deployed to AIR, the JavaScript / ExternalInterface calls 
will probably need to be re-written.  I wonder what your JavaScript 
calls are doing that is important to the application.

Subject: [flexcoders] Re: Problem with Accordion Component resizing.

 

Tracy,
Ok, when I setup the accordion to display a 4 part form (kind
of like a wizard style) I chose certain dimensions for the height and
width. Those dimensions, the height and width, apply to the
Application, the Panel, the Accordion and the display area on the
accordion, which is based on the Form component. 
I'm a little confused because when I returned to the project,
just now, it seems to be different. It is reflecting the dimensions,
that I had chosen earlier. This is weird. It just was ignoring the
height and width settings when I tried to change the height and width
on each of the different components, going from Application, to Panel,
to Accordion to Form, in the container ship hierarchy. Now, when I
came back, just moments ago, it's different, it shows the height
values I was using. Another wierd thing that it was doing, was that
I'd change the value on the height of these components and it seemed
to just go back to the older value (which was smaller) or to some even
smaller value.
OK, this just seems wierd but it does seem to be ok now. I'll
have to wait and see if this happens again. Maybe it wasn't updating
or refreshing. I don't think that this explanation is valid though.
Thanks,
Bruce

You are probably going to have to monkeypatch Seb's component.

to line 166 of CoverPlane.as

seems to go somewhat towards the functionality you need.

Note that you will need to download the source from

the source from the demo page as this appears to be older than the

Hi all,

I have been experimenting with using the custom install badge by Grant
Skinner (http://www.adobe.com/devnet/air/articles/badge_for_air.html),
however, for some reason the background image specified by "imageurl"
does not display, even in the example badge. Instead of displaying the
background image, the appname and version are displayed in blue text.

I've tried using both relative and absolute URL's, PNG's and JPG's,
and checked to make sure the permissions for the file were okay, but
nothing worked.

Any suggestions?

Thanks,

[flexcoders] Re: Some material for flex 3 Certification

[nathanpdaniel]

Flex from the Source (from Adobe Press) is a really good one to get 
your head wrapped around Flex - if you would consider that 
book "basic" or easy, you'll do fine on the Flex portion.  Or you can 
try the online Flex training 
(http://www.adobe.com/devnet/flex/learn/designer/learningpath.html).
Then, make sure to study AIR - the main areas you should focus on are 
the differences between Flex & AIR (like the file system stuff, HTML, 
etc. - things you can do in an AIR app you can't do in a web app).
Get those 2 things - and you should be good to go.  That's what I 
did - of course it DOES help significantly if you are a full time 
Flex developer... But if you can't do that, there's really enough 
material out there to understand it...

[flexcoders] Re: Flex RegExp issues

[mmormando]

We faced a similar problem where I'm working, everyone had to
implement a filtering mechanism using user input, including some
special characters. While we were comparing solutions it was noted
that all but mine had troubles with the special characters.I was
just using indexOf(string)>-1 rather than the RegExp methods. Now,
they kind of had me beat when we had to make it case-insensitive, they
only had to add the "i" second parameter whereas I had to upper or
lower case everything, so I had to type more characters there, but it
was still way less than the escaping code they had to add. 
I guess long story short is, take a look at all of the tools in the
box, and make sure you're using the right one for your use-case.

Note that this is a "quick fix."  If you think you might want to reuse

cs.addChannel( myChannel) ;

Re: [flexcoders] ActionScriot file in Componet

[Jeffry Houser]

Can you share some code?  Something like this should work:


include 'myfile.as';


However, if you're "myfile.as" is an actual class definition, as 
opposed to ActionScript snippets I would expect that to cause odd errors. 

Additionally, how do you define "Whole Path?"  I've always used a 
relative path from the includee file.

Try just setting the blendMode on the textArea to "layer", and see if 
that will let you rotate it without embedding.  I found that 
ImageSnapshot sometimes didn't work with fonts that were not embedded.

[flexcoders] Re: AdobeFlexBuilder 3 AIR: problem with Exported Release Build

[dmkramerica]

I just solved the very same error. Which, after research, has multiple
causes.

What I found was:

If you have .png files in a folder called "assets", for some strange
reason it will not install.

Delete that folder (in both the /src and in the /bin-debug or
/bin-release folders), copy the those .pngs to another folder first
obviously (I called mine /img). Then make sure all your .png file
references are correctly "re-pathed" in the code (and I ditched all
unused files and all .DS_Store files too for good measure) and it
installs.

I have not found a really good explanation, but working = good.

The certificate issues (another possiblity I found posted on the web)
turned out to not be my issue, but you may want to look into that too.
It's documented on the Bug List too.

Hope this helps.

Now...can I get some help on my last post? I'm feeling dumb.

[Bret Phillips]

This may be of help to you:
http://livedocs.adobe.com/flex/3/html/help.html?content=data_access_2.html

explains the usage of http service and gives example in both php and 
coldfusion. Outlines request, server side processing of response, and response 
return.

Hope that helps.

[flexcoders] AdobeFlexBuilder 3 AIR: problem with Exported Release Build

[samir_npatel]

Hi Frnds,
I am using Adobe Flex Builder 3 and have created an AIR application.
I want to create a 'Build' so that I can install it and run it
independently.
So I created it using 'Project' --> 'Export Release Build'.
It creates MyProject.airi file. When I click it to install it, it shows
following error...

"The application could not be installed because the  AIR file is
damaged."

I tried with many different applications, but same result.

please help...

[flexcoders] Question about MVC in a Flex Application

[carlo giordano]

Hi,
I would share infomation about how is used the MVC in a Flex
Application. I have begun to use Pure MVC two months ago but I don't
know if is very useful.

If someone use different MVC framework and would like to share tips
would be appreciated.

Thanks for attention.

[flexcoders] Sandboxed Modules in AIR

[rob_mcmichael]

I was wondering if you could help me.

I would like to run a download and potentially untrusted Module
(written as a Felx SWF,  ) into an AIR application. This
would be a bit like Tour de Flex, but downloading and storing the
modules locally rather than loading them from a remote server every time.

There are the problems I have faced:

- Not being able to load then as normal because they are not in the
application directory, and also not being able to move them there at
runtime.

- Loading them via a ByteArray, but being unable to then put them in a
sandbox, or restrict their ability using a parentSandboxBridge.

- Getting the well documented "SWF is not a loadable module"
(http://www.mail-archive.com/flexcoders@yahoogroups.com/msg82210.html)

- Not being able to reference loaderInfo.parentSandboxBridge in my
module (should I get the rest working) as parentSandboxBridge is in
the AIR framework, but I need to create a SWF to load in as a module.

If you could help me with any of these point I would really appreciate
it, I will also be happy to document the solution if found.

Thanks

[flexcoders] DataGrid - variableRowHeight="true" and wordWrap="true" not resizing properly

[patrickfkellogg]

I have a DataGrid that has dynamic columns (see below).  when i set
the DataGrid's variableRowHeight="true" and wordWrap="true" it resizes
tall and wraps just fine when a cell's contents are really long.

The problem is the next time the DataGrid appears when there is no
data to display it doesn't resize the row height to a normal row
height.  It remains at the previous really tall height.

The fix typically for this is to set the wordWrap="true" in the
DataGridColumn tag and not in the DataGrid tag, but since i am
generating the columns dynamically, I can't do this.  Any one seen
this?  any fix?
thanks. pat kellogg 

 

[flexcoders] navigateToURL and "_self" - Works locally, not when swf is on remote server

[uclamerrick]

I have an Image on an ApplicationControlBar and I am trying to make it
such that when the image is clicked, the current browser window/tab is
redirected to a URL. It works when the swf file is opened locally, but
not if its a remote swf file. I am guessing this is some security
issue, and am wondering if anyone has found a way around this.

This works
Opening the swf file locally, and clicking the image loads the new URL
as specified in the imageClick function below. 

This does not work
Opening the swf file remotely using an html page with object/embed
code and clicking the image *does not* load the URL.


import flash.net.navigateToURL;

public var myURL:String;

private function imageClick(evt:MouseEvent):void {
myURL = "http://www.yahoo.com/";;
navigateToURL(new URLRequest(myURL), "_self"); 
}

[flexcoders] Add FXG graphic from external file into application

[Jan Tošovský]

Hello Everybody,

I've found similar topic in this discussion, but it probably covers slightly
different thing:
http://www.nabble.com/Loading-.fxg-with-Actionscript-td21009054.html#a210090
54

In my case I load the external FXG file into a XML variable. Now I'd like to
convert this XML code to the Graphic element and to add it to the app. Is
this possible? Or there must be used a different approach?

Jan

My root element is Application, where Group element is not permitted. And
what is 'comp'? To which object all this content is added by the last line?
Is there any more complete sample how to do similar things?

[flexcoders] looping through xml (newbie question)

[annelie2008]

Hi,

I'm trying to loop through my xml, but I'm having some problems. I 
thought this would give me all the line nodes, but it's empty:

var xmlLines:XMLList = myXmlList..Line;

Is that the right way to go about it, or is there another way?

Xml code is below.

Many thanks,

Annelie

[flexcoders] Re: Displaying UIComponents vertically

[annelie2008]

Turns out it was my fault entirely, I hadn't checked the xml code 
properly and assumed it was supposed to give me three vertically 
stacked staves but it was actually showing them horizontally. I will 
check more properly before posting a question in the future.

Thanks for answering though!
