Flex :: Flexbuilder - Organize Application For Compile Performance?
Jun 28, 2010
I'm preparing to reorganize & refactory a Flash Builder application. The goals of the reorg are 1.) keep compile times for the part of the project I'm working on as fast as possible, 2.) keep the unrelated parts separate for code reuse. Goal #1 trumps goal #2 if there's a trade-off.
Currently, the app has assets in one project, core functionality AS3 in another project, and the MXML in a third project that links to the other two.
Would moving resources/code into swc libraries help compile time? What about compiling assets into an swf and embedding that into the main application?
I have .fla called Helicopter and a movieclip in the library with a linkage of Fly. If I use the code-snippet(as a seperate class called Helicopter.as)below with Flash or Flashdeveloper it works fine. If i use FlexBuilder (Actionscript project)I get these errors. is there some settings I have to change in FlexBuilder?
Severity and Description Path Resource Location Creation Time Id 1046: Type was not found or was not a compile-time constant: Fly. Helicopter/src Helicopter.as line 7 1247730594859 770[code]....
I am working on an Adobe AIR (2.0) application that contains a feature to allow users to print documents (such as salary slips). Those documents are originally in PDF format. Due to circumstances we cannot directly display those PDFs in the AIR application (for example using flash.html.HTMLLoader). Therefore we convert the PDFs to SWFs (using the pdf2swf tool, see The SWFs are loaded into the application using a mx.controls.SWFLoader, like so:
I have a flash application which consist of Grid Components, Button, Label, and Combo-box Components. All these components are used more than 70 times(simultaneously) with in the application. So Its takes too much of memory. So How can I test the memory usage of each component at the time of running. Is there any plug-in available for browsers to find the memory usage. I'm using flash CS3 and ActionScript 3.0. The application suppose to run in browsers.
Will I take a big hit in performance using nested ViewStacks? Should I strive to handle all navigation in one ViewStack and push children manually or will the affected performance be negligible?
We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?
There is probably no way for this but does anyone know a method of excluding certain functions from a build by use of a meta tag and or compiler option?I want to expose some functions for testing but not have them bloat the application on production. I could create separate testing classes and test for a complier directive or option and only load them if necessary but I like the idea of having the test function on the actual object (in the class).
I have a problem with my flash application because after a while that it is running, it eventually starts to slow down. My application involves something that needs to be replicated with the addChild() method. I've read some info on the internet which states that the cause of the slowing down or the lag in the application is that the removeChild() does not remove the child from the memory
I have a lot of the following warnings:Duplicate variable definition.variable 'elem' has no type declaration.Illogical comparison with null. Variables of type Boolean cannot be null.Will they affect the performance of my flash application? Will they affect the compiling time?
I'm using as container for my LinkButtons. I would like to know 1) How can I remove the space between the items in my Tile container. 2) How can I set dynamic width for my items (at the moment they all have the same width regardless the width of the included component) 3) How can I avoid to display scrollbars if the items are not included in the container
I m trying to install Flex Builder 3 into Eclipse 3.5.1 as a plugin on Mac 10.6.2.During the installation phase, FB3 says it only support eclipse 3.3 & 3.4. But I started the installation anyway. After the installation was done, I can't find Flex perspective from Eclipse. So I google around and found out the possible way to manually add this link file from folder "links" to point to the FB3 Plugin folder. I did that and FB perspective can be shown now. But when I try to switch to FB perspective, error occurs:[code]
I'm working on a project on Flex AS3.0 project in Flex Builder. It was working fine, I changed the name of one of my classes and all the related process. Now when I compile dubug the thing, it keeps on compiling an older version even if I comment all the code in main. It still compiles the old files. I have cleaned the project , but still the same old problem.
It's growing pains time again. Some of our stuff requires FlashBuilder 4 and some still requires FlexBuilder 3. Both are installed OK, and no projects use both IDEs. The trouble is, when I go back to work on a FlexBuilder 3 project it takes freakin' forever to build and I get weird errors like these: This doesn't seem to cause any identifiable problems except to throw up a modal dialog at various points in the build process, forcing user interaction. But I do notice that memory fills up fast in FB3 and generally FB3 starts behaving strangely and ultimately quits once it gets up over 700MB.
This is only a temporary bridge situation until we get all projects into FB4, but "temporary" could mean weeks if not months. Does anyone have any advice for how to get through this bridge period? Is there anything I can do to make these two IDEs work and play well together? Failing that, does anyone know what "java.lang.String" is the "reason" for the problem? Does Eclipse have a resource bundle somewhere that is getting corrupted when i go back and forth between the two?
is there any documentation on the FlexBuilder "expressions" tab, and what expressions it can accept?As far as I can tell, it can show the value of variables, but that's it: comparisons, function and method calls all fail: [code]this is specific to FB3 Flex Builder. Apparently FB4 Flash Builder is slightly less incompetent.
I am not using FlexBuilder, I'm using the free Flex SDK with TextMate. I'm having some trouble figuring out what this FlexBuilder process actually does behind all the nice dialogs and things, so that I can do the same thing by tweaking whatever the relevant file is, but Googling just points me at similar instructions telling me to use FlexBuilder.
We have an AIR application running on an Apple iPad, that occasionally experiences sudden drop in its performance. The frame rate drops from 60fps to 2fps and it never recovers from that. this is only reproducible on iOS 4, but never on iOS 5 - we've checked that on two identical iPads (generation 1)the performance drops occasionally, but always happens when we switch between apps - from our app to another and back very rarely, the performance drop also happens on first start of the app this performance issue does not happen in renderMode=CPU, but this mode doesn't work for us, because the rendering is ugly, especially on rotated bitmaps.
I have created an Adobe AIR application that interfaces with Salesforce.com. The only drawback I have is that the data that is synced to the desktop is not encrypted. I can encrypt a database that I create locally, however, I am trying to encrypt the database that is created and maintained by the flexforforce toolkit.
I am creating an application using flex mobile but could not find how to show alerts using flex.So can anyone please tell how to show the alert in flex mobile , mx alert don't work in this and i could not find an alternative in spark.
I am having a problem that I cannot figure out. I have searched the internet, describing as best I could and I could only find one other person with the same problem as me and no one replied to his post. Here's to hoping someone knows what is up.My App was working fine yesterday, then I added a few lines of code to a class file. When I tried to test the movie, it wouldn't compile. It would just run through all of the frames flashing each control. It does not output anything to the Output window nor the Compiler Errors window, which is odd because even when it would compile before it would output some warnings to the compiler errors window.
So I went into the class I changed and commented out the changes I made. Still will not compile.Also, when I try and go and Debug the movie, it tells me "You cannot debug this SWF because it contains no Actionscript". I've tried researching this problem as well, but it seems that this problem occurs when people are using the Document Class. I am not using a document class. My actionscript is on the frames.This same problem happened for the first time on Monday, but by tinkering with files/settings, it was fixed. That is until yesterday when i made that change.
I am using a custom Flex skin to create an active blur/frosted glass effect on the background of floating Panels, TitleWindows, and other containers (similar to http:url....). There is a background image in the Application skin, and potentially any number of other components above and below the active blur component. Here's some relevant code within the skin:
public static const BLUR_FILTER :BlurFilter = new BlurFilter(16, 16, BitmapFilterQuality.HIGH); private var _bitmapFill :BitmapFill = new BitmapFill; private var _matrix :Matrix = new Matrix;[code]....
Unfortunately, the performance of this when the component is being resized, and especially when moved, is poor. There is noticeable drag delay and overall slowdown, and this is with only one popped-up TitleWindow in the test application. There is especially poor performance when components inside the TitleWindow are changed (button hover states, etc.)I've attempted to optimized a little bit by avoiding reinstantiation of the blur filter, bitmap fill, and matrix, but this has had little or no effect. I removed the blur at one point, just drawing the Application to a bitmap, and the performance is still poor, so it's clear that it's mostly the BitmapData.draw() call.
I've read about using scrollRect and cacheAsBitmap, but I'm not sure where to apply these properties (or other optimizations I'm not aware of) within the Application or its components.
I'm trying to set up the swiz framework in flex but cant seem to get it to compile. Im using swiz 0.6.2 and flex 3.0.2. The swc is in the libs directory of my flex project. Im following the tutorial here:[URL] and my code looks like:
[Code]....
when i try to compile i get the error unidentified method loadBeans through a reference with static type Class.
I've noticed that, recently, builds in FlexBuilder have been taking much, much longer than they used to (30 or 40 seconds, as opposed to 3 or 4). What is the simplest way of profiling these builds to figure out what is taking so much time?
