Re: [flexcoders] Profiler telling lies?

[Mark Doberenz]

Check your event listeners because if you're not using weak references  
then the garbage collector won't remove it. Disregard if you already  
knew that one :)

Hi all,



I’m trying to work out where a memory leak is occurring in our appli

When profiling the app, it claims there is still a back reference to  
its parent on the display list (even though I remove it!) at  
[child0]. When I debug the application, the child is removed as I’d  
expected, and the children array is empty.


So which one is lying? The profiler when it tells me there is still  
a back reference to the parent as [child0] or the debugger when it  
tells me the child has been removed…

Re: [flexcoders] using an event to trigger an action in a sibling component

I tend to create a public method on my Login screen called reset() or
something like that.Then, I can easily call it to reset that form.

Try Flexlib.  It has a really nice canvas button component.

Re: [flexcoders] Re: Modules not loading in some browsers! Why?

[Mark Doberenz]

It also may be that you're not making a hard link to the module and it's
getting garbage collected before you're doing anything with it.

I don't remember exactly the details, but I had an issue with modules
sometimes loading and sometimes not loading between compiles of my app.
Once I added a hard reference to the module once it was loaded, that went
away.

The garbage collection could play differently between browsers which is why
the modules get garbage collected in some browsers and not others.  There
could be a better way of saying that.  It's not that the garbage collector
behaves differently, but some browsers might have a larger overhead than
others and so the GC may get rid of stuff differently.

Re: [flexcoders] Howto Create Flex Builder Custom Component folders?

[Mark Doberenz]

Johannes,
  I was actually thinking that this would be what I'd need to do.  Do you
have any more info on what this would look like?
  Creating an installer for this library wouldn't be a big deal, so
packaging up the eclipse plugin and the swc wouldn't be out of the
question.  I just don't know how to do it.

[flexcoders] Howto Create Flex Builder Custom Component folders?

[Mark Doberenz]

I'm creating a Flex library project for work and it's ending up being a
BUNCH of little custom components.  So, when I use the library in a Flex app
project, there are all of those components in the "Custom" Components
folder.

Is there any way to create a new folder in the Components tab in Flex
Builder?  I tried searching for this before I'm posting this, but I can't
find anything about it on the web.

Any help would be greatly appreciated.

Re: [flexcoders] Error #2044: Unhandled ioError:. text=Error #2032: Stream Error.

[Mark Doberenz]

I came to find out that this is a general error that gets sent to Flex when
an error is getting generated by the server.
Essentially, the error is throwing an error.  I'd suggest using Fiddler to
see what the communication is and what the actual error is.
A limitation of IE/Firefox hosting a Flex app is that the browsers do not
send the data to the Flex app.

What needs to happen is that you need to try to send the fault back as a 200
MSG_OK that contains the fault information.  Flex will then parse the info
and throw an error.

That's what I had to do recently using Axis and I'd assume Spring is
similar.

Re: [flexcoders] Module Preloader?

[Mark Doberenz]

Can't you just have the module start up in a state that has some sort of
"loading" screen and then it transitions to a different state once the
data's loaded.

States or View Stacks could both work to do this.

Re: [flexcoders] Application Help.

[Mark Doberenz]

Date has a year property
just loop through something like this

var dArray:Array = new Array();
var d:Date = new Date(birthDay.time); // This will create a new instance of
a Date with the same time as the birthday
var now:Date = new Date();
While (d.year < now.year)
{
dArray.push(d);
d = new Date(d.time);
d.year++;
}
Then the dArray will have a list of dates.  Your datagrid can have some
datacolumns with functions that define the value in the grid.

Hope that helps,
Mark

Oh for cryin out loud

All I had to do was create an array of ModuleLoaders and add the
ModuleLoader to it when I created it and it kept all the instances just
fine.

Thank you so much  I can work on this project again!

Re: [flexcoders] Re: ModuleLoader 'SWF is not a loadable module' Error

[Mark Doberenz]

I've worked on an app too where I used modules heavily.  I had/have issues
where the module doesn't load.  I've noticed that the trace log shows that
the SWF is decompressed, but it never throws the Complete event.  I've found
that sometimes recompiling the app will work.

I'm not sure if it's an ApplicationDomain issue or not.  I tried tweaking
this a while back and never got anywhere, but once I removed it, the modules
started loading.  I didn't have issues with it anymore until just recently
when I started the project back up again.  It made me not work on the app
b/c I'm tired of hacking with this issue.

Unfortunately, I haven't found a way to really fix this. :(

[flexcoders] Flex and Server-Side Java classes

[Mark Doberenz]

All,
  I've been a part of this list for a long time and I'm a pretty decent Flex
programmer.  However, I'm not too familiar with the server-side aspect of
things.
  I wanted to post a server-side noob question for you experts out there.

  If I have a couple existing applications, one that runs in JBoss, one
that's .NET with a SOAP API, and I want to set up a broker system using java
and JBoss, is it possible to have Flex make Remote Object calls to the
broker system if I DON'T use LCDS?  In other words, do I need LCDS to call a
server-side Java class?

  Please no flames regarding this question.  If I've said something
incorrectly, please let me know so I can learn more about this stuff.  I
hate that I don't even know the questions to ask. :(

Thanks,
Mark

what's the namespace that the custom component is in?  You may need to
specify the full namespace location:

Re: [flexcoders] good examples of dynamic rendering

[Mark Doberenz]

Yeah, but they can be a bit slow regarding rendering time.

If you can get away with doing a List and setting it's ItemRenderer to a
Component, it may get you what you want also.
This is the way I try to do things since I heard that Repeaters are slow
rendering-wise...

Re: [flexcoders] Re: Variable width ListItems

[Mark Doberenz]

You put a repeater inside a hbox and set dataprovider of the repeater to
what you're using on the list box.  It's not normally best practice to do
this, that's why Alex asked if you had a lot of items in the list.  Using a
repeater is much slower in rendering time than a list.

[flexcoders] Re: Modules not positioning children correctly

[Mark Doberenz]

Well, in case anyone else has this issue, I found a bit of a hack to get it
to work.
I just created an mxml class called CustomModule.mxml and this is all that's
in it:



http://www.adobe.com/2006/mxml"; width="100%"
height="100%">




Now, whenever I make a new module, I just point it to the CustomModule
class as the main class to use, and everything resizes/positions fine.  I'm
not sure why, but I'll take it.

Just to make sure, I changed one of my modules to point to mx:Module again,
and the children didn't resize/position correctly.  Setting it back to
CustomModule made it all work again.

Hopefully this can help someone.

Re: [flexcoders] Apollo HTMLControl capabilities

[Mark Doberenz]

 Yeah, I just saw that yesterday.  It looks promising, but the whole
software renderer isn't going to quite cut it.
 I work for a software company called Right Hemisphere and we have a free
3D viewer called Deep
View<http://www.righthemisphere.com/products/deeppub/DeepPub_View/index.html>.
This is really what I'd need to hook into the project I'm working on.  We
have a need to push LOTS of polys and I don't think a software renderer
could cut it.  However, that said, I'm going to look into Papervision3D to
see what it can do.
 It's an ActiveX control, so I'm wondering if I can have apollo actually
open up another HTML webpage in IE and then using LocalConnections,
communicate with Deep View the way I've currently got it set up.  That might
be the way to go now that I think about it.

 I'm very open to other ideas though.

[flexcoders] Can't add objects to a new Apollo window

[Mark Doberenz]

I have an Apollo app that I want to make open another window and load a
module into it.

I'm following the instructions from this page...
http://labs.adobe.com/wiki/index.php/Apollo:Documentation:Working_with_windows#Creating_windows

I can make the new window appear, but nothing ever shows up in it.

I then used the createNewWindow() method from the page above and that worked
fine.  It created a new window and showed a nice graphic in it.

I then tried just adding a Label to that window by doing the following bit
of code:
var label:Label = new Label();
label.text = "Test Label";
label.x = 10;
label.y = 10;
newWindow.stage.addChild(label);


However, that didn't add the Label to the window.

I had previously tried adding a new ModuleLoader to the new window.  I added
event listeners to the ModuleLoader and it seemed to be loading the module,
and then added the module to the child property of the ModuleLoader.
However, just like the label, nothing appeared in the new Apollo window.

Any help on this would be GREATLY appreciated.

Cheers,
Mark

[flexcoders] Apollo - multi-window communication

[Mark Doberenz]

 I've been thinking about using Apollo for an extension to an app I've been
working on in Flex.
 The current issue with the Flex app is that it's locked to a web browser
and really only runs on one screen.  I know you can stretch the web browser
across multiple screens, but that's not quite what I want.

 I know Apollo has windowing capabilities and it seems to be quite nice as
far as transparent / custom windows goes, which is pretty cool.
 However, one thing I'd need to be able to do is have one window
communicate with another window by passing certain bits of information back
and forth.

 So, here's the $64,000 question "Does Apollo allow for communication
between different app windows?"

Any info on this would be GREATLY appreciated!!!

Re: [flexcoders] Root Node open when displayed.

[Mark Doberenz]

Do you even need the root node to be visible?
If not, there's a ShowRootNode property and you can set it to false.

Might be easier, might not.

Re: [flexcoders] Cairngorm Duplicate Remote Object Return Events

[Mark Doberenz]

OK, I was able to finally get somewhere with this...

Here's what I was using in my Delegate in the login method...

var call:AsyncToken = service.login(username, password);
service.addEventListener(ResultEvent.RESULT, responder.result);
service.addEventListener(FaultEvent.FAULT, responder.fault);

The problem was adding the event listeners to the service node... not a good
idea, but like I said earlier, this is how Sam Shrefler was doing it on his
tutorial.

Here's what I changed it to...

var call:AsyncToken = service.login(username, password);
call.addResponder(responder);

Now, I'm only getting one result every time I call the method.
Hope this helps someone else.

Your idea of the UID sounds like it will work but I'd prefer not send
extra data back and forth and it also won't clean up these redundant event
notifications.. It seems that cairngorm creates new instances of the
delegate/event listeners etc every time, maybe there is a way to find a
unique reference for them that you can use to filter out the extra events?
but I guess that still creates a memory problem and the application will get
slow after a while, something that would easily happen in a chatroom
application for example.. question is: how does someone kill these event
listeners with cairngorm?

All,
 Thanks for this discussion!  I hadn't heard of this before, so I googled
it and found this article:

 I'm going to try this out and see how it works.  Then maybe I'll be a

 I am undecided as to whether or not I want to use the code behind

OK, so maybe having a Singleton delegate wouldn't be a good idea.

Here's a bit more I've found on the topic.

I put a breakpoint at the Command result method and found that the address
location for the commands were changing.  So, essentially, the commands are
being persisted which in turn are persisting new instances of the delegate
and the event listeners that are a part of those delegates.  Removing the
event listener in the delegate first won't work because the memory locations
of the responder (the command) are changing.

Essentially, every time you create a new cairngorm event, you will create
new instances of the delegate and then the event listeners, so the same
result will fire the event listeners multiple times when you've created
multiple cairngorm events.

That's at least my take on the issue.

I have an app where I'm trying to perform a LoginEvent and I noticed that
every time I hit the Login button, I was creating a new LoginEvent and so
the more I tried to login, the more results I was getting back.  I tried
making the LoginEvent a private var on the view, and that seemed to work the
first time, but after that it wasn't passing the user data anymore.  Not
sure what that's about.

I don't like this fix because it would mean that there's only one instance
of each of the cairngorm events in the whole app.

Re: [flexcoders] Cairngorm Duplicate Remote Object Return Events

[Mark Doberenz]

OK, so maybe having a Singleton delegate wouldn't be a good idea.

Here's a bit more I've found on the topic.

I put a breakpoint at the Command result method and found that the address
location for the commands were changing.  So, essentially, the commands are
being persisted which in turn are persisting new instances of the delegate
and the event listeners that are a part of those delegates.  Removing the
event listener in the delegate first won't work because the memory locations
of the responder (the command) are changing.

Essentially, every time you create a new cairngorm event, you will create
new instances of the delegate and then the event listeners, so the same
result will fire the event listeners multiple times when you've created
multiple cairngorm events.

That's at least my take on the issue.

I have an app where I'm trying to perform a LoginEvent and I noticed that
every time I hit the Login button, I was creating a new LoginEvent and so
the more I tried to login, the more results I was getting back.  I tried
making the LoginEvent a private var on the view, and that seemed to work the
first time, but after that it wasn't passing the user data anymore.  Not
sure what that's about.

I don't like this fix because it would mean that there's only one instance
of each of the cairngorm events in the whole app.

I'm going to try a couple of things - one is to explictly remove the event

  Try setting a breakpoint in your delegate and look at the memory address
for "this" and see if it's changing each time the delegate's called.

sounds like the most likely thing to be happening.

try setting a breakpoint on where you remove / add the listeners and check
that
the references are the ones you expect, i.e. you are not trying to remove
a
different listener or something.

[flexcoders] Using "As" with a string Class type

Re: [flexcoders] Intermittent #2032: Stream Error errors

[Mark Doberenz]

I had this issue for a long time.
I'm hoping this is a webservice call you're trying to make, and that it has arguments that are needed.  Say the arguments are arg1 and arg2 and they both take string values.  Also assume the function is called func1.  Here's what I would suggest...

 
var func1:Operation = webserviceObject.func1;
func1.arguments = {arg1:"value1", arg2:"value2"};
func1.send();
 
The issue is that the argument list for webservices (and possibly http requests) are hash tables.  Hash tables don't guarantee order, so you need to create an object and specifically assign a value to a property.

 
After I implemented this, I pretty much got rid of all of my stream errors.
