Re: [flexcoders] Large Flex app architecture
Agreed: I just did a write-up today on the very subject. http://www.mossyblog.com/archives/441.cfm It's got me baffled as to how to fix this as I know for a fact at work killing a browser and what not just won't be done on most cases for long periods: I mean if were to use a Kiosk style approach to allow folks in board-rooms and what not to initiate actions, thats an environment where browser refreshes will occur every now and then. We also make use of large Smartboards (picture really big touch-screen but works like a whiteboard) at work and well, they often sometimes keep the one browser open a lot aswell - well could be the case anyway.

Our factory has also the job of destroying views (and related models, command instances and helpers). We've been very careful trying to destroy every piece of non use memory to avoid issues, however, after some days of use (if the user doesn't reload the app) the application will stop responding and we'll have to kill the browser.

I'm attacking my FLEX archiecture much in the same way i would with a traditional web paged system. I've looked at Screen by Screen approach where typically you active a screen for a task. Example: TravelAuthorization Request Form (Wizard Format) = Screen1 TravelAUthorization Admin Form = Screen 2 TravelAuthorization Summary / Report = Screen 3 etc.. Now each of these screens have their own sub-screen lifecycle (ie much like the FlexStore where checkout form replaces product pod and so on). Anything that significantly breaks away from a parent Screen becomes a screen onto itself. Once I formulated a pattern for this and broke my approach into screen by screen, I am then going to use a destroy / create approach. I'm hoping that my theory holds that Flash Garbage collection will free up memory every time i destroy a screen, but this is a Intranet Application so bandwidth isn't my top priority here (while i should be mindful of it) - so I plan to use Run Time Shared Libraries but will quite happilly kill an asset and move it to a download every bite situation if need be. I will use view stacks up until a point, and then i'll have my own quasi view stack manager to attack the same problem. Again, I am not finding much information on how FLEX Garbage collection works and what key tricks i need to make sure are in place, so the above may not hold water and won't know until I have it fully tested and working but surely a destroy/create approach should work and if it doesn't by god MM you better make it happen soon or i'll...i'lll bah..i got nothing. hehe. I posted on my blog on how I am attacking this screen by screen approach, via this: http://www.mossyblog.com/archives/434.cfm Its a framework I am working on and its ripped off a few concepts from Mach-II and Apache Cocoon.

var t = baseStack.createChild(aList[itm]);
baseStack.selectedChild = t;

Both browsers continue to ask for more memory
every click of
createChild and Destroy. Furthermore when you
click on LinkBar items
(back and forth randomly) I noticed that it too
increases memory.
I then noticed if you refresh your browser memory
(thankfully) reverts
back to its original size.
After 15 mins the best result I got was:
Internet Explorer:
before: 51,000k (give or take)
after: 55,500k (give or take)
15mins: 55,400k (give or take)
FireFox was pretty much the same results.
Q. Am i destroying incorrectly? should i do
something else first? ie
what should i do.
As over a long period an application can easily
climb in memory usage
and the only counter-act for this would be to
change mxml files via
url when they go from screen to screen? it seems
cumbersome but that
appears base don the above to be a possible
solution?

You could set up your Python modules as services: 1. Web service on Tomcat? 2. Simple CGI script that returns data in XML format. This can be accessed from Flex using HTTPService. You could also try wrapping your Python module into Java using Jython, and then access it using RemoteObject from Flex. I'd go for the service way (HTTPService to keep it simple). Flex can also send data to your Python module via the CGI script in XML format (using HTTP POST?) or as URL parameters (HTTP GET). Manish Yahoo! Groups Sponsor ADVERTISEMENT Yahoo!

I just grepped over my literally hundreds of MXML and ActionScript source files and didn't find a single MovieClip reference. The fact that Lazslo separates itself from the Flash Player is another benefit as well.. If something should ever happen, maybe legal issues or whatever, Lazslo can output to, say, Java applets or whatever, since the code is all abstracted from the VM and the compilation process handles the dirty work of putting your code into a format the VM can understand. Ditto for Flex. 1) You don't write Flash code in Flex. 2) In theory, it's possible to output Flex (MXML/ActionScript) to a different output format. Manish Yahoo!

chr() is deprecate in favour of String.fromCharCode() since Player 5.
My questions:
1, how to insert a unicode directly? Like unicode(61657)
textObject.text = String.fromCharCode(61657) + Dec 31, 2005;
2, how about specify a font and code for one character and then specify

Create two Label objects and place them adjacent to each other. The
first Label object would contain the special character in Webdings
font.
mx:Label text={String.fromCharCode(61657)} fontFamily=Webdings /

The numbers os bytes will redirect to the browser navigator temporary

Re: [flexcoders] Flex 1.5 price
Actually, i mentioned this on the weekend to some soon-to-be FLEX converts, the new price model will be cheaper for us lol.. As we bought FLEX pre-Price hike, @ $15k (AUD) (2CPU) Now thats great, but if we have servers that are DUAL CPU (which is common pract in most comps) we'll need a dev product copies... thus $15k USD x 2 . which is in the end more exp ..plus i don't think we get Gold Support on the pre-price. So there ya go, it was cheaper in the end for us to wait.. (thats of course if we prefer to live on 1xCPU servers then well... 15k AUD was cheaper ) On Apr 4, 2005 2:15 PM, Igor Costa [EMAIL PROTECTED] wrote: Agreed with JesterXL, go to the Monster.com and see some bites, really good.

In my opinion Flex is really a good way to develop quikly applications but the prices is the great hide seek. So, STOP all blesment about that, if you can't work and offer to your costumer a flex solution jump to Flash. other simple way. But really as Lucian Beebe said ( we are offering packeges for your solutions and your projects ), look for it and ask, that's simple Don't be acomplishment for this thread.

Re: [flexcoders] Memory Leak?
Sorry, I missed all that ? how do you tell the player to allocate memory?
On Apr 4, 2005 2:18 PM, Igor Costa [EMAIL PROTECTED] wrote:
Scott has a trick inside this problem set your player to the 0% of memory
size for record on the right-click of mouse and test again.
The numbers os bytes will redirect to the browser navigator temporary
directory and the computer will waste less time and less memory
worked with me when I had the problem.

hrmmm..
I'm guessing the player will be released at the end of this year? if
that being the case I'll just continue on as normal (knowing the
memory leaks are there) and await the player (that and inform our
support staff that a browser closure is recommended when not using
apps).
Thanks for the input though Matt ;)

I dunno whats going with GMAIL as I tried sending this earlier but
kept going to Matt only...
Heres a memory Leak test thing I did.
I did a basic script which looks like this:
mx:Script
![CDATA[
public var IsViewStack:Boolean = false;
import mx.containers.*;
import mx.controls.*;
import
com.SynergyFLEX.viewpods.test.testpod1;
import
com.SynergyFLEX.viewpods.test.testpod2;
import
com.SynergyFLEX.viewpods.test.testpod3;
import de.richinternet.utils.Dumper;
function loadPod() {
if(IsViewStack) {
} else {
var aList = new Array();
aList.push(testpod1);
aList.push(testpod2);
aList.push(testpod3);
aList.push(Button);
aList.push(TabNavigator);
aList.push(Accordion);
aList.push(Label);
aList.push(TextInput);
var itm =
Math.round(Math.random()*aList.length);
Dumper.info(itm);
var t =
baseStack.createChild(aList[itm]);
baseStack.selectedChild
= t;
}
}
function delPod(indx) {
baseStack.destroyChildAt(indx);
}
]]
/mx:Script

Both browsers continue to ask for more memory every click of
createChild and Destroy. Furthermore when you click on LinkBar items
(back and forth randomly) I noticed that it too increases memory.
I then noticed if you refresh your browser memory (thankfully) reverts
back to its original size.
After 15 mins the best result I got was:
Internet Explorer:
before: 51,000k (give or take)
after: 55,500k (give or take)
15mins: 55,400k (give or take)
FireFox was pretty much the same results.
Q. Am i destroying incorrectly? should i do something else first? ie
what should i do.
As over a long period an application can easily climb in memory usage
and the only counter-act for this would be to change mxml files
Re: [flexcoders] Flash and Flex
Golden Rule I live by: What you can do in FLASH, you can do in FLEX. The catch22, is that sometimes in flash you can setup a container.swf, and load in an other.swf that makes use of variables items within container.swf itself. That works cool, but I'm a bit sketchy on this one, that if you import a Flash build SWF into a FLEX app via loadMovie for example and inside this other.swf is say V2 Controls (Flex look-a-likes) i'm unsure as to how the two will collide? ie FLEX uses its own flavoured version of the v2 framework where as FLASH has its own version and not sure if there will be two sets brought in. But, for a test case i build a Modeler SWF in FLASH which basically lets you drag shapes on stage and connect nodes to these shames (pretty much the same as MS Word Workflow Tool) .. it works fine in FLEX but i dare not as yet try and use variables within that swf inside flex? but in theory the two should be able to. I guess be careful with the two frameworks? but you should be able to live by the same rules/boundaries as if you where using two SWF files to communicate with one another either via localConnection or via swf within swif approach.

Are there any limitations between the actionscript I can use in flash compared to what I can use in Flex? Is the goal just to use flash when complex animations are needed or is flex limited in such a way that flash is needed more often if you are doing heavy user interactions and animations? Yahoo!
