Flex :: Adobe Air Filtering Large Datasets?

Sep 30, 2009

I have an Air app that downloads a data set of around 100`000 objects and puts the objects in an ArrayCollection.I would like to apply various filters to the data set in numerous screens throughout the app. am a little worried about possible performance issues if I make multiple copies of the collection. However, if I don't copy the collection any filters applied will be reflected in all the screens and this is not the behavior I need.

Flex :: Adobe Flash IOS Packager Throws Java.lang.OutOfMemoryError When Packaging Large Projects?

Jul 20, 2011

I've been porting a Flex 4 codebase to iOS using the adobe packager, but have run into a snag when trying to package our whole codebase. The packager runs for a while and then throws an OutOfMemoryError - even if I increase the java heap size to 4GB. No single piece of code seems to be causing the problem, as it compiles successfully if I cut out large chunks of code, and I can change which chunks I'm omitting. It might be related to the size of the code itself.I've logged a very detailed bug report with adobe here: ou can package to reproduce the issue, a ruby script that generates actionscript codeto generate that AIRI file, and a summary of all of the things I tried before logging the bug.

Flex :: Filtering By Attributes Has Undefined Variable

Aug 24, 2010

I have some xml and I am trying to filter it using e4x. My e4x statement looks like this:
model.config.source.fees..fee.(@min<amount).@amount

My xml looks liks this:
<flex><fees>
<fee type="credit" min="0.00" max="200.00" amount="6.00"/>
<fee type="credit" min="200.01" max="370.00" amount="10.00"/>
</fees></flex>

When the e4x statement is run, I get an error message:
Error #1065: Variable @min is not defined.
But if I change my statement to model.config.source.fees..fee.@min it will return an xmllist of all the min attribute values, so min is defined, at least in that statement. Why doesnt the original statement work?

Flex :: ArrayCollection Fast Filtering (one Chart At A Time Is Not Option)

Sep 19, 2011

I have the following situation: have a screen with 4 charts, each being populated with 59 array collections. Each array collection has 2000+ data points. This construct needs to be filtered(by time), but the problem I'm encountering is the fact that it takes a long time for the filtering to finish (which is to expected given the amount of data points that need to filtered).

Filtering one chart at a time is not option, so I wanted to ask you what do you think would be the best approach? (should I use vector instead?). To generalize this question what would be the best way to filter large collections in flex/as3?

Actionscript 3 :: Filtering Datagrid Based On Data In Rows, Flex?

Mar 23, 2012

I've search all over today trying to find how to do this, and not being familiar with actionscript is starting to catch up to me. What I would like to accomplish is: I have a list of messages in a Datagrid coming from a dataprovider in another class, which in turn gets them from our Oracle DB. I need to all the user to set a visible state on the message, and then filter that out of the datagrid with the click of a button. I have the check box for hide, and it sets that value into the database. I can't figure out how to get the filterFunction to work with an array collection when the filter parameter is within the row data.Here is the code

public function filterResults():void {
modelLocator.notification.messageList.filterFunction = filterRows;
modelLocator.notification.messageList.refresh();

Flex :: Performance - Printing From AIR/Flex Application Causes Large Files Being Sent To Printer?

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).

Flex :: App With Large Number Of UI Objects Is Slow

Jun 10, 2009

I'm building my first Flex custom component, in Flex 3. It is a data table based on the 'Grid' container class, with a simple text Label in each cell. (DataGrid and AdvancedDataGrid were not appropriate starting points for my needs.) The component works quite well using smallish tables, but I tried stress-testing it using a larger table, and have been disappointed by the results.

The component creation process has some slow spots, but those are in my power to optimize and aren't my primary concern. What worry me more are what appear to be limitations in the Flex framework itself.

This 'large' sample table has a bit over 7000 cells in it. This is largish, but still 1-2 orders of magnitude less than the biggest I need to accommodate. In standard Grid structure, the main portion of the component consists of a Grid with 400 GridRows of 16 GridItems each, plus a few other smaller ancillary Grids.

Once the table renders, I find the following:

Mouse-related events are slow to fire. Specifically, I have rollOver/rollOut event handlers registered on each table cell, to let me highlight the cell under the pointer. On a small table, I could move the mouse over the table very quickly, and the highlighting would follow the pointer in real-time. With the larger table, the highlighting is very jerky, changing only about twice per second, skipping over many cells.If I place the mouse cursor over the component and leave it there, my CPU is pegged (one processor core, anyway), and stays that way until I move off of the component, when it drops to idle. My component isn't doing anything at all at this point.

It feels like Flex simply cannot scale to support component trees that are this large. I shudder to imagine how it would behave with 100,000 cells. Perhaps I'm pushing the Grid beyond its intended use, but having an object per table cell doesn't seem like an unreasonable model, and ~14,000 objects in the tree (a GridItem and a Label per cell) seems pretty modest.

Flash :: Saving Large Images Created In Flex?

Nov 25, 2009

I am attempting to capture a very large image that was made dynamically within the Flash Player (the size of the image is 2400px by 12,000px) and am running into some very serious issues... Let me run down how the image get's to that size in the first place:

User adds elements to a canvas and then when the user is finished the canvas scales up to 2400px wide and ~12,000px tall. The problem arises when I attempt to save the image to the hard drive. Now, I dont know if this will affect the recommended fix, but the rendered image wont be saved on the hard drive, it will be sent to a server. I know about the ~4050px limit in Flash Player and was thinking I could get around that by clipping the images with the ImageSnapshot.captureBitmapData() method and keeping the required Rectangle variable below 4000px then repeat that down the large image until it reaches the end where the final images will be pieced together at a later time. However... As i mentioned the error comes when it reaches the 'fileReference.save(pngImage);' method..

Flex :: Workarounds For Flash Bug When Drawing Large Shapes?

Dec 12, 2009

When you use Graphics object to draw very large shape(that does not fit in 10000x10000 pixels) stroke width may become much wider than value specified in lineStyle function.For now I have only two options:

1. When drawing line you can split it into several lines. However this trick does work only for drawing lines, polylines and polygons. There is no way to apply this to drawing circles and ellipses. Well, we can approximate circles via bezier curves, but this approach seems to be very inefficient.

2. Perform manual cliping. But this require manual implementation of different cliping techiniques, and I think ActionScript does not suit well for this sort of task. And again there is need to approximate visible parts of large circles.

Flex :: Get Dimension Of Locally Loaded Large Image?

Feb 12, 2010

I'm trying to read the width and height of a locally loaded image. This seems to work for images that do not exceed the dimensions limited by the Flash Player 10 [URL], but as soon as the images are bigger, the width and height remain 0. The strange thing is that now and then, I can read the dimension of these bigger images, but most of the times not. I understand that this might be because of the player limitation, but then I would at least expect the error to be consistent.

I want to check this since there is no use in loading such a big image as it will not be displayed anyway, but it would be good to provide a detailed error message to the user.

Here's the code that I use to load the image locally and read the dimension:

private function chooseImageButton_clickHandler(event:Event):void {
var allowedTypes:String = "*.jpg;*.png";
m_uploadFileReference = new FileReference();
m_uploadFileReference.addEventListener(Event.SELECT,

Flex :: Build A Large-scale Application For Free?

Oct 13, 2010

I want to create a fairly large-scale Flex web application that has a similar interface style to Grooveshark.

When it comes to web development, I have always used the common PHP/HTML/JavaScript technologies. Now, I want to try something new and develop a RIA using Flex.

Using PHP/HTML/JavaScript, I am able to develop my entire website with free tools. Now, I'm wondering if I am able to do the same thing with a Flex web application?

Is it possible/feasible to develop a Flex web application for free? If not, what would be the lowest cost I would need to spend? And, whatever the option, what are the tools that would be needed?
