[flexcoders] FileReference for file uploading, how to specify the folder to open?

[Mat Mikul]

Hi!

I need to upload a file from flex. I know the path and the file name
already, but haven't figured out a way to be able to upload in the
background. This is likely due to some security restrictions posed by
Adobe to ensure sites cannot upload files from the user's computer
without their explicit permission. I can live with that for the
moment, but then I don't want the FileReference dialog box to open
always in My Documents. I'd rather it opened in the folder where the
file is, and that I can specify the file name so that all the user (if
they are ok with it) needs to do is to click Ok.

How can I specify default folder location?

Re: [flexcoders] LCDS: DataService.fill() not filling

[Brendan Meutzner]

Geoff,

1) check the data-management-config.xml file to be sure your data  
type, unique Id value, etc are correct


2) make sure your array collection is not null prior to passing into  
fill method on service ( ie. new ArrayCollection() on var first )


HTH,

Brendan

Does anyone know what would prevent a DataService.fill() call to not

I have an ArrayCollection that is the dataProvider for a DataGrid. I
see that data is coming back from the fill() call, but it doesn't
appear to be passing that data to the ArrayCollection. If I inspect
that variable after the fill() completes, it's empty.

I double checked that the ArrayCollection that I'm passing to the
fill() method is indeed the one that is used as the dataProvider.

Any thoughts would be appreciated.

[flexcoders] Re: dataGrid effciency

[Tim Hoff]

Hi,

The biggest performance culprits with a DataGrid, or any of the ListBase
components, is the itemRenderers and the size of the dataProvider.  You
can optimize the itemRenderers by using UIComponent; see Alex's blog. 
And depending on how many items are in the dataProvider, you could see
performance issues there as well.  If you are performing any
calculations you might look at ways to tighten up the code.  With a one
second refresh, you might be asking too much of the UI.

hi everyone,  i used dataGrid  to display  a  list of  real time data.  when i

the DataGrid has 13 DataGridColumns, every column  almost  nest  a

the data update every second, and  i  need to  change the components’ style in 
some columns following the data.  as i know  these two aspects

who konws  how to optimize it or other ways to  achieve.

Is integration and a resulting much, much better experience not enough
of a reason?  As a matter of fact, good part of what Adobe does so
well is already done in pieces elsewhere.  The reason why Adobe does
it well is in great part due to nothing more than better integration
and a resulting better experience.

If Adobe wrote such a SWF to FLV converter then they could offer it to
YouTube and other sites so that they could accept uploading of SWF
files, on which they would then do PERFECT conversion into FLV or some
other format.

There is another thing Tom that you totally fail to recognize and that
is the quite poor quality of most of the videos that are currently up
on YouTube. A lot of quality is lost in the process of using various
settings of frames per second and Kb or Mb per second, that may or may
not match what YouTube uses and then one's video ends up going through
yet another conversion, resulting in yet another decrease in quality.
Giving YouTube a perfectly beautiful looking SWF presentation and
letting them convert it to FLV with whatever settings suit them the
best, would most likely result in the best possible video quality.

When all is said and done Tom, be assured that most of the folks out
there (most of them not being technical) can not tell nor figure out
why ADOBE FLASH MOVIES look so bad on YouTube.  Most of them know how
to right click on one that they are watching and BINGO, we know what
they see will UNFORTUNATELY in most cases cause them to erroneously
think that FLASH IS CRAP FOR VIDEO.

Sorry Tom but since (with a statement like that) you seem to know very
little about how Microsoft operates, I will explain it to you.

Time is the only thing that is on Adobe's side.  Eventually, Microsoft
will end up eating everyone's lunch, at least on the desktop.  It
causes me a lot of pain to say just that but it is true. While they
have a lot of catching up to do, within a couple of years they WILL
catch up to Adobe - technically speaking.  With another 2-3 years,
they will catch up in the field as well - in terms of deployments.

Tom, like it or not, there will not be anything that will be more
beatiful then an end-to-end .NET code (C#, VB, take your pick) that
stretches from the clients/devices and all the way through the servers
and into the database itself (stored procedures).

Unfortunately, they WILL end up eating everyone's lunch because of the
beauty and a much, much better developer experience due to such an
end-to-end integration.  Just the type of lousy integration, a small
piece of which I suggested earlier.

P.S. You just happened to be the closest official one on my path of
frustration. Please take my comments constructively and not at all
personally, even though that might end up being hard to do, at least
from a first reading.

And thanks for replying.

[flexcoders] Re: How do they do that (Flex & video)

[comfederation]

No it's not OK ;)

When a company has different file formats then it's really sad and
unfortunate to have to rely on third party tools for conversion
between those formats - if for no other reason then integration and
overall better experience. 

My laymen understanding is that FLV is a streamable video format and
like you said SWF is like an exe.  Well actually it's more like Java
byte code in that it is a stream of byte code that is only
understandable by the Flash Player.

If you look back through some of the responses or maybe they are on my
other post, you will see that at least one person on this forum has
suggested using SnagIt or some other screen capturing tools. No,
indeed it is not OK if folks who are evidently at least dabbling with
Flex and there they are suggesting third party screen capture tools.  

Not only is it not OK but it is quite sad that Adobe, who is smack
deep in this space, has left even one developer thinking of resorting
to such band aids. I for one am disgusted by it and only because they
know the best how to "play" a SWF file and how to capture the video
"stream" that comes out of it.

Enough said on my part.

P.S. However, your reply is not only OK but it's also much appreciated
as well.

"you can display it somehow, maybe by setting a tooltip somewhere" -
Getting the text isn't the problem, getting it to display is! :)

I want the tooltip to display whenever someone mouses over the cell in
the custom ItemRenderer's column (just like it works when I don't
specify a custom ItemRenderer). Any idea how to accomplish this?

[flexcoders] Re: creating a class - question extending

[Michael VanDaniker]

Image, like all UIComponents, has a zero argument constructor.  Unless
your imageWithData knows what its username is going to be without any
outside info, it wouldn't make sense to do much of anything with the
username in the constructor.  If you're going to be instantiating your
images in Actionscript you can just assign the username after the
object is created.

It is not a service but a component to use to create this autocomplete  
behavior. You simply use the yahoo component library swc in your Flex 
application. The manager will use whatever data you want it to. check 
out these examples for a better idea of how it works.

Re: [flexcoders] JavaFX and Flex how do we compare?

[Josh McDonald]

Thanks for that info Chet, you're definitely in a unique position to offer
insight.

Would I be right in saying that compared with FX Script (ie, without writing
Java2D / Swing code), AS3, Degrafa/FXG and MXML provide a lot more power in
terms of custom component and skin creation? This is the way it seems, but
that could be completely the fault of Sun bungling their PR as usual ;-)

I'm also interested in the differences and similarities between JFX's
bindings and those supported in Flex if you can find the time to elaborate
on the subject.

Cheers,

-Josh

Many classes have a ToolTip property you can set.  For instance, 
UIComponent.  You can even use the ClassFactory approach to specify a 
ToolTip function to use to make your itemRenderer more reusable.

RE: [flexcoders] JavaFX and Flex how do we compare?

[Chet Haase]

I would be curious to find out how others view the platforms, especially from 
the standpoint of external application developers, but having been on the 
inside of both of these projects, here are some points of comparison. I'm 
attempting to be objective here and just point out some of the areas to 
consider. But since I used to work at Sun on Java/JavaFX and now work on the 
Flex team at Adobe you should filter appropriately.


-  Maturity: One of the reasons that you haven't heard much about 
JavaFX to date is that it's actually not yet released. Supposedly this will 
happen in the very near future, so maybe we'll all hear more about it at that 
time.

-  Language: Although many of the underlying capabilities of JavaFX  
rely on the Java SE platform, JavaFX itself is based on a new scripting 
language (not Java, not JavaScript, not ActionScript, but a new scripting 
language entirely). One notable differences between the languages of JavaFX and 
Flex is that Flex uses MXML for its declarative aspects, and ActionScript for 
the programmatic aspects. The JavaFX language combines both of these elements, 
having aspects of declarative and programmatic in the same code.

-  GUI capabilities: Both platforms offer GUI components, graphics, 
animation, and databinding capabilities, thought the platforms differ widely in 
syntax and capabilities of these different features.

-  Tooling: Most of the tooling so far announced for JavaFX are more on 
the code developer side; editing plugins for NetBeans, plus export plugins for 
Illustrator and Photoshop (they produce PNG files from the layers in the 
project). On the Flex side, there's the FlexBuilder IDE and the in-development 
tools such as Flash Catalyst for designer/developer workflows and FXG roundtrip 
import/export from/to the CS tools including Catalys for the graphics tags in 
the Gumbo release of the SDK.

-  Runtime availability: The availability of the JavaFX runtime is 
basically that of the Java platform (if a user's machine does not have the 
proper release of Java (I believe it will require the latest updated 10 
release), they will need to download/install it). The availability of Flex is 
basically that of the Flash platform of the appropriate version (e.g., Gumbo 
will run on FlashPlayer 10).

[flexcoders] AIR Cairngorm Application Command Architecture

[zwigby]

I have question about setting up an air application architecture using 
cairngorm commands. So the application has very complex calculations 
that have be done in steps and I am not sure the best way to lay them 
out in cairngorm. A general example is as follows: there are 5 
different calculations which can be done. Each of these calculations 
involves multiple steps. Each step may have to lookup information in 
the local database. Some of the steps are reused from calculation to 
calculation. So I was thinking of each calculation being a command and 
then the steps would be helper classes that use delegates to get the 
information from local database. Any thoughts would be great. Thanks 
in advance.

[flexcoders] Is it this difficult to purchase Flex in south east asia?

[Yohanes Iwan Sugiarto]

Hi..

I'm sorry if this question goes a little bit out of topic.
I live in Indonesia and would like to purchase Flex 3, so I contacted
a local reseller/distributor (this distributor does listed in the
Adobe's website). FYI, there's no Adobe representative here in
Indonesia, Singapore is the nearest.
Short story, I paid full for my purchase in 22 Sept, and they promised
at least 2 (two) weeks of delivery time.

But until now (so it's been almost 2 months), they were still unsure
when they can deliver Flex.
My last contact with them was last week (10 Nov) and they asked me to
wait about 3 or 4 weeks more.

I don't quite understand what's their problem and what cause the delay
(they only said "need more time to deliver")
Can you imagine, 3 months to get a software that is suppose to be
already released?

I wanted a full refund and think of buying online, but they said my
order were already processed through Adobe Singapore.
Can anyone help me? should I wait again?

What kind of charts are you displaying?  I've had amazing success with
scrapping the charting framework all together and simply "drawing" the chart
programmatically.  Yes, it's a bit more work, and yes it's only feasible if
you don't really need a lot of the charting features that come in the
framework.  However, the performance difference is huge. 


The project I applied this on was for financial stock data, and using a
custom drawn chart I mention above, along with the concept someone else
mentioned by only showing the n-th datapoint interval depending on the
overall range being displayed worked quite well.  You're able to keep a
consistent number of plot points (I've found 500-750 performs best) no
matter what the overall range of data you're displaying.  I say 500-750
performs best as I also had a horizontal axis slider which allowed for
constantly updating data in the chart.

On a more serious note, I have to agree with Fotis and Ricky that 50K
data points is too many, both from a (Flash 9 VM at least) performance
perspective and probably also from an Information Visualization
perspective (unless, maybe, your users have 300 dpi monitors).

There are several standard interaction design and information
visualization techniques which may be useful to you . . .

1) Aggregation (as already suggested, take 'N' data points, average
them, and then only display the average value).

2) Filtering (by sliders on an axis, by date/time, by structured or
open-ended queries, ...)

3) Progressive rendering (sample the entire data set at intervals of
'N', render those points, then go back and get the data which is
mid-point between the original points, add the new points to the
curve, repeat until desired resolution obtained--or on user demand)

4) Non-linear zooming (like idea 1), but allow user to zoom in on a
section of the curve, when they do, add the additional data points to
the curve for the zoomed-in region)

On a more pragmatic note, you certainly _can_ plot more than 2,000
points. For example, I've personally used Flex to create charts with
over 14,000 points in them, so I know that at least that number is
definitely *possible*. However, the overall

RE: [flexcoders] Re: Creating a Chart With 50,000 Data Points

[Mark Easton]

I'd be using C++. :)
 
I already have a C++ application running on our gateway which deals with
grabbing data from the stations. It then passes that to a parser utility I
wrote so that would be a good place to reduce the dataset ready for a
progressive display on a flex chart. 
 
Yep - a very interesting application!

[flexcoders] Strange ADG error on deleting entire nodes at once...

[Adrian Williams]

All,

   I could really use some help in identifying where even to begin 
looking to figure out what's causing this problem.


   I have a ADG that is displaying a GroupingCollection. 

   I have an application control bar that has a "trash" image.  A user 
can drag a node from the ADG and drop it in the trash to delete the node 
and all it's children. 

   When you initially get into the application and drag the first node 
of the tree to the trash, the delete fires correctly and without error.


   When you try to drag the (now) first node of the tree into the 
trash, I get the following error:


TypeError: Error #1010: A term is undefined and has no properties.

   This only errors when manipulating the second time you try to delete

without error.  I suspect there is some kind of out of index problem 
happening but the dump gives me no ideas on where to look.

[flexcoders] Re: Flex 2 charting license with Flex 3 sdk

[schneiderjim]

Maybe it should help, but I'm not sure. 

I don't really care about extracting the source code. Should I?

Does this imply that I still need a Flex Builder 3 Pro license in
order to use charting in my Flex 3 SDK app?

Is my Flex 2 charting license rendered useless/invalid once I upgrade
to the Flex 3 SDK?

[flexcoders] Re: May I save BitmapAsset instance to database?

[Michael VanDaniker]

Your question is a bit vague, but I'll try and be of some help.

You can use the ImageSnapshot class to get the ByteArray the backs
your image. Then you can store those bytes in a database and pull them
up later.  If you're building an AIR application and saving the image
to a local database you'll want to read up on the SQL utilities
available to you here:

http://livedocs.adobe.com/flex/3/langref/localDatabaseSQLSupport.html

If you're building a browser app you can pass the ByteArray to a
webservices or a remote object that will store the image in a database.

http://livedocs.adobe.com/flex/3/html/help.html?content=data_access_4.html

If you can be more specific about your problem, we can provide more help.

My question is how would i get all the entries in the list except the
entries with the pool in the list. Basically i have all the data and
the list having the data with id as 'pool', All i need is all the
entries from my data without id 'pool'. Below is my code for getting
entries for the pool name. Please let me know if anyone has any idea.

I don't think so. The output I get is

 

param1=0 param2=0 param3=bar

 

If it was using the default values, param2 would be 1, not 0. I think it
is simply coercing null to 0.

The defaults aren't always null, and MPO is that the developer
shouldn't need to know what the appropriate default is to make the
default behavior. I feel like I'm really sure that I've seen places in
the framework code where functions are called this way, but I'm not
sure how to search in there to get verification.

[flexcoders] May I save BitmapAsset instance to database?

[markflex2007]

Hi,

I create a BitmapAsset instance from image class and I want to save it
to database and other people can see the image when he read out
BitmapAsset instance from database.

Do you think if it is possible? and how to save and read from database?

Thanks

I don't think so. The output I get is

param1=0 param2=0 param3=bar

If it was using the default values, param2 would be 1, not 0. I think it is 
simply coercing null to 0.

The defaults aren't always null, and MPO is that the developer
shouldn't need to know what the appropriate default is to make the
default behavior. I feel like I'm really sure that I've seen places in
the framework code where functions are called this way, but I'm not

RE: [flexcoders] Re: HTML IN FLEX

[Gordon Smith]

AIR includes a very complete HTML+JavaScript engine (WebKit), but this engine 
is much too large to include as part of the ordinary Flash Player.

Flex 3 components such as  which have an htmlText property are 
based on the Player's flash.text.TextField class, which supports a small  and 
nonstandard subset of HTML. See the htmlText property of TextField in the 
Language Reference for a list of what tags and attributes are support in 
htmlText markup.

Adobe is developing a new Text Layout Framework (TLF) which works with the new 
Flash Text Engine (FTE) APIs in Player 10. (It will be used in Flex 4.) TLF 
will not support all of HTML, but it will be more capable than TextField's 
htmlText.

 I think the Text component is setting the text format of its TextField to 
correspond to the CSS styles set on the Text component. The inheriting CSS

RE: [flexcoders] Re: Creating a Chart With 50,000 Data Points

[Mark Easton]

Thanks Brendan,
 
We are charting observations from a range of sensors and contact inputs. The
contact inputs are a special case as they can only have 1 or 0 values. But
the sensors include temperature, current, voltage, light, humidity,
vibration, motion, gps velocity, gps location, wind speed, wind direction
etc.
 
The client does like the the charting features so he wants all of the flex
charting cool stuff as well as the ability to see these charts. 
 
But that does not mean that I cant look at a combination of approaches. Its
a good idea to look at coding a custom chart, and one I will look at
closely.
 
Yes I was thinking along the lines of having 2000 plot points. So in the
case of a 3 month graph I would start with 120,000 points and need to reduce
that to 2000.
 
Cheers,
Mark

What kind of charts are you displaying?  I've had amazing success with
scrapping the charting framework all together and simply "drawing" the chart
programmatically.  Yes, it's a bit more work, and yes it's only feasible if
you don't really need a lot of the charting features that come in the
framework.  However, the performance difference is huge. 


The project I applied this on was for financial stock data, and using a
custom drawn chart I mention above, along with the concept someone else
mentioned by only showing the n-th datapoint interval depending on the
overall range being displayed worked quite well.  You're able to keep a
consistent number of plot points (I've found 500-750 performs best) no
matter what the overall range of data you're displaying.  I say 500-750
performs best as I also had a horizontal axis slider which allowed for
constantly updating data in the chart.

On a more serious note, I have to agree with Fotis and Ricky that 50K
data points is too many, both from a (Flash 9 VM at least) performance
perspective and probably also from an Information Visualization
perspective (unless, maybe, your users have 300 dpi monitors).

There are several standard interaction design and information
visualization techniques which may be useful to you . . .

1) Aggregation (as already suggested, take 'N' data points, average
them, and then only display the average value).

2) Filtering (by sliders on an axis, by date/time, by structured or
open-ended queries, ...)

3) Progressive rendering (sample the entire data set at intervals of
'N', render those points, then go back and get the data which is
mid-point between the original points, add the new points to the
curve, repeat until desired resolution obtained--or on user demand)

4) Non-linear zooming (like idea 1), but allow user to zoom in on a
section of the curve, when they do, add the additional data points to
the curve for the zoomed-in region)

On a more pragmatic note, you certainly _can_ plot more than 2,000
points. For example, I've personally used Flex to create charts with
over 14,000 points in them, so I know that at least that number is
definitely *possible*. However, the overall rendering time was (as I
recall) over 3 minutes long. More troubling was the fact that the
entire Flex UI become very sluggish once a chart that large was
displayed. I've seen good chart rendering speed ( ~= 2S ) and no UI
sluggishness, up to about 1500 points. I've also been able to render
up to 6,000 points, but it took about 10S for the rendering and the UI
started to become sluggish. From your posting, it sounds like you're
not seeing those rendering speeds. I'd recommend that you experiment
with how you are using the charting objects/API. My experience was
that I was able to see some very noticeable speed-ups simply be
optimizing how I called the charting API (especially w.r.t. how I
loaded the series data). In particular, if your charts are
interactive, try to cache anything you can that doesn't necessarily
change during an interaction (i.e., axis objects).

Last thought: the new Flash 10 VM (Astro) has support for larger
bitmaps and also can now do hardware-based rendering, apparently. I
haven't tried either of those features myself, but using the v10 VM
_might_ be another way to get a performance boost, etc.

Good luck!

RE: [flexcoders] Re: Creating a Chart With 50,000 Data Points

[Mark Easton]

Hi Jim,
 
Yes, LOL ... and it gets worse when we try to plot a graph for one year
(about 500,000 observatons).
 
We are plotting values received from sensors (eg temperature, vibration,
humidity, gps location, gps velocity, wind speed, current, voltage, light).
We take readings each minute.
 
I have produced a dashboard which uses the following techniques:
 
1. Each sensor graph is in its own window ... so can be looking at 10 graphs
at the same time for instance.
2. I average data to reduce the dataset size 
3. I employ drill down
4. I have included a slider to look at reduced time frames
 
The client rejected this solution. I did some tests in flex and found
results similar to you Jim. When I tried to plot 40,000 points I gave up
waiting for it after 6 minutes. 10,000 points took about 20 secs the first
time (including reading from the local sqlite data store).
 
The client and I have now agreed that:

1. If we have a large number of observations from a sensor and plot all of
those on a graph over a period of time, then whatever optimisation we use to
improve performance should produce an identical looking graph to the first.
(I think that identical is probably to strong a word here)
2. We will add a confif paramter for each sensor such that the sensor
readings can be changed to occur at multiples of 1 minute. For example,
every 10 minutes.

So, I will still end up with data sets to large for flex, and given that I
want to display many graphs at once and will also be looking at representing
many sensors on the one graph this contributes to the issue.
 
So, I do need to sample the dataset somehow to make it work. But have to try
to meet the goal expressed in point 1 above.

I think a combination of your points 3 and 4 might be a good approached
combined with some algorithm to ensure that my top level curve does not miss
an max's and min's and as close as possible approximates a full detail
curve.
 

A few challenges there!
 
Thanks again,
Mark

[flexcoders] Re: HTTPService with mixed parameters

[valdhor]

When I try your code and check it with Charles
(http://www.charlesproxy.com) the method is GET and the URL is
http://my.url/service?params=%5Bobject%20Object%5D&method=getMessage&pre\
feredMainTextPartTypes=%5Bobject%20Object%5D

I have no idea how you would get the data in this situation as Flex
sends [object Object] as the parameters. If I were you I would add a
function to serialize the data before it is sent:

 private function sendTheData():void
 {
 var theURL:String = "http://my.url/service?";;
 for(var key:Object in params)
 {
 theURL += key.toString() + "=" +
params[key].toString() + "&";
 }
 jsonRequest2.url = theURL;
 jsonRequest2.send();
 }

As an aside, if you need to send both GET and POST parameters, set the
service to POST and add the GET parameters to the url property of the
HTTPService.

To send objects I would recommend using RemoteObjects.

[flexcoders] Re: Creating a Chart With 50,000 Data Points

[jim.abbott45]

50,000? LOL. ;-)

On a more serious note, I have to agree with Fotis and Ricky that 50K
data points is too many, both from a (Flash 9 VM at least) performance
perspective and probably also from an Information Visualization
perspective (unless, maybe, your users have 300 dpi monitors).

There are several standard interaction design and information
visualization techniques which may be useful to you . . .

1) Aggregation (as already suggested, take 'N' data points, average
them, and then only display the average value).

2) Filtering (by sliders on an axis, by date/time, by structured or
open-ended queries, ...)

3) Progressive rendering (sample the entire data set at intervals of
'N', render those points, then go back and get the data which is
mid-point between the original points, add the new points to the
curve, repeat until desired resolution obtained--or on user demand)

4) Non-linear zooming (like idea 1), but allow user to zoom in on a
section of the curve, when they do, add the additional data points to
the curve for the zoomed-in region)


On a more pragmatic note, you certainly _can_ plot more than 2,000
points. For example, I've personally used Flex to create charts with
over 14,000 points in them, so I know that at least that number is
definitely *possible*. However, the overall rendering time was (as I
recall) over 3 minutes long. More troubling was the fact that the
entire Flex UI become very sluggish once a chart that large was
displayed. I've seen good chart rendering speed ( ~= 2S ) and no UI
sluggishness, up to about 1500 points. I've also been able to render
up to 6,000 points, but it took about 10S for the rendering and the UI
started to become sluggish. From your posting, it sounds like you're
not seeing those rendering speeds. I'd recommend that you experiment
with how you are using the charting objects/API. My experience was
that I was able to see some very noticeable speed-ups simply be
optimizing how I called the charting API (especially w.r.t. how I
loaded the series data). In particular, if your charts are
interactive, try to cache anything you can that doesn't necessarily
change during an interaction (i.e., axis objects).

Last thought: the new Flash 10 VM (Astro) has support for larger
bitmaps and also can now do hardware-based rendering, apparently. I
haven't tried either of those features myself, but using the v10 VM
_might_ be another way to get a performance boost, etc.

Good luck!
Jim

Good to hear it's not just me.  And on such a different system, as well.  I
updated the bug with my code for the simpler test version.

Does anyone know if they read bugs that say "resolved" but have been

Actually, it looks like I *can* repro, even building from source. I'm
not sure what is different between this time and the previous time doing
it. Steps are even simpler:

1. Click on chart, move mouse around (app traces out
mx.charts::ColumnChart)
2. Click on chart, move mouse again (app traces out null)

Well, I tried it on another machine (also running XP), with FP9 and the
error count be reproduced.  Upgraded to 10 on that machine, error could
also be reproduced.  So clearly it's not that.  Could be the version of
the player for Windows, maybe.

I'm attaching the HTML/SWF to see if it reproduces if you use the SWF I
generated.

As such, I changed the code so that it has a text box (so you don't need
to look at the console output).  If you click on the chart twice in a

[flexcoders] LCDS: DataService.fill() not filling

[Geoffrey]

Does anyone know what would prevent a DataService.fill() call to not 
populate it's managed collection?

I have an ArrayCollection that is the dataProvider for a DataGrid.  I 
see that data is coming back from the fill() call, but it doesn't 
appear to be passing that data to the ArrayCollection.  If I inspect 
that variable after the fill() completes, it's empty.

I double checked that the ArrayCollection that I'm passing to the 
fill() method is indeed the one that is used as the dataProvider.

Any thoughts would be appreciated.

[flexcoders] Flex 2 charting license with Flex 3 sdk

[schneiderjim]

We purchased the Flex 2 charting license. Now, we have upgraded to the
Flex 3 SDK. We haven't (yet) purchased Flex Builder 3 as we/I don't
use Flex Builder very much. I do command line/ant builds and editing
with my text editor du jour. 

However, since upgrading to the Flex 3 sdk, we are now getting the
"data visualization..." watermark. 

Is there something I can do with my flex 2 license.properties to get
this to work? In Flex 2, there was some command-line stuff with
charting-source.jar that I needed to do. Or, do I need to
purchase/upgrade to Flex Builder 3 (Pro)? If the latter is the case, I
think I read that I can just put the license in the flex-config.xml
file. Is this true?

Thanks,

Jim

Re: [flexcoders] Can you spare 5 minutes to reproduce this 12 line bug?

[Pan Troglodytes]

Not to worry.  Clearly the bug reporter couldn't reproduce it, so I'm not
shocked that someone else can't.  All I need is for some people who CAN
reproduce it to prove that my computer doesn't somehow magically work
differently than everyone else's.  But you do make me think of something -
maybe it's dependent on Flash Player 9 and the tester only used 10.  Will
have to try testing that.

RE: [flexcoders] Custom ItemRenderer and DataGrid/DataTips - Renderer's Responsibility?

[Alex Harui]

Implement IDropInLIstItemRenderer.

The labelData will have a columnIndex where you can get the dataTipFunction and 
run it (see DataGridItemRenderer.as).  Once you have the text, you can display 
it somehow, maybe by setting a tooltip somewhere

I have a DataGrid with a custom ItemRenderer written as an
ActionScript class (that extends HBox). I want the DataGrid to
display datatips for this column, but no datatips appear!

I've found a few "bugs" filed about this, but apparently this works as
designed:
https://bugs.adobe.com/jira/browse/SDK-9822
"Not a bug. It is the renderer's responsibility to deal with
dataTipFunction. This is for performance reasons."

So the question is...
How does a custom ItemRenderer deal with the dataTipFunction to create
/ display the datatip?

I know the ItemRenderer is responsible, so can someone give me an
example of how to fulfill this responsibility? :)

RE: [flexcoders] SWFLoader - displaying parent application

Classes from a child SWF that are also in the main app are not used.  The main

Hi,

I'm trying to load a SWF application that I created using Flex 3 (with
FlashDevelop) into a parent application. I tested using a SWF I downloaded
from the internet and it loads correctly. When I try to load the swf that I
created, it loads (I get all the events, similar to the one working) but
instead of displaying the child swf, it displays another instance of the
parent application where the child should be!

The app I'm testing with is the example in the Flex 3 documentation. It just
contain a simple Label to confirm that the app was loaded.

Your help will be greatly appreciated, as I'm dumb struck that one work, and
the other not..

Hi Alex,

Thanks for reply and I hope this time I could explain it well.. :)

the dialogue window pops up at a particular position in the page, and when I 
scroll down the page(when I come to the bottom of the page) the popup also 
comes along. But what I want is the popup should go up with the main page..

For example this pop up generates at a text input and I need the pop up to 
stick to that text input i.e where it was generated originally. Instead now it 
gets detached from the text input and moves down with the page when scroll down

RE: [flexcoders] Re: Security sandbox violation: local SWF files cannot use the LoaderContext.securityDomain property

[Alex Harui]

First you have to identify which code is causing the violation.  Post the 
entire violation.  It should contain more information about which component is 
doing the violation.  Once you figure that out, then you can try to workaround 
it, but testing from the server instead of the local filesystem is recommended 
as someday you will deploy the app to a server and you'll have different 
security rules in such a configuration.

  it says that it will take on AJAX and Silverlight. 
  It will also have desktop runtime like AIR, I guess!!! 
  SUN was also in MAX, San Francisco and there they also 
  talked about it. Now I want to know how do we compare

RE: [flexcoders] modules or something else? + Mate

[Alex Harui]

If the cpu is bogged down by the creating of children, I don't think modules 
will help.  Modules defer loading of the code for a view or component, but at 
some point you still have to instantiate it and create its children.

I'd figure out what the bottleneck really is and work around it.  If there's 
1000's of children, but you can't see all of them or don't need all of them, 
create some, and create others in batches via callLater.

I have never used modules so I am not sure if what I am trying to do
will work for them or not or maybe there is an easier way to resolve
this issue.

I have an app that has several documents. Each document is made of a
canvas with an accordian in it. In this accordian I have two vboxes
(thus to slides). The first vbox, which is shown on automatically, is
a bar graph. The second vbox is a very heavy large custom component
that is cpu intensive to create.

Here is what I am currently doing, which freezes up my browser. In
vbox1 I call this
creationComplete="vbox2.createComponentsFromDescriptors()"

which means I am creating the children of vbox2 when vbox1's
creationComplete event is dispatched. I do it like this so that when
the user clicks vbox2 view it, its ready to view and they don't have
to wait on it to load.

The other way I was doing it was waiting for vbox2 to open and then
creating the vbox2's children, which still causes the browser to lock
up until it complete, but then they are also looking at a blank
background. I tried to use an animation so they would have something
to look at, but the animation stops because the browser is locked up
do to CPU cycles be eaten up by my heavy components creation being so
CPU intensive.

I am not sure if moving to a module would solve this issue as I have
never used them? Do they load like a flex appliation (progress bar)?
And if I go with modules can through events like a regular component
so my main app can listen for the events?

I am using Mate so if that matters?

LoD.  Large scale datasets can work the same way computer graphics do. 
Users don't normally need to see every data point when a summary will 
do.  Provide the user with the minimal amount of information necessary 
to understand what the data is saying and let them use the interface to 
drill down into specific areas.

This works really well if you pre-calculate and cache the results on the 
backend (and predictive caching on the front doesn't hurt either).

[flexcoders] MouseEvent.MOUSE_WHEEL fires twice in Firefox

[hu22hugo]

The mouse_wheel event triggers always twice in Firefox. IE7 fires
correctly only one event. Find below a simple test case. Can anybody
confirm this behavior and maybe a workaround?

Thanks,

Re: [flexcoders] Re: How do they do that (Flex & video)

[Fotis Chatzinikos]

flex and video are different things...

Flex can play video easily, the same applies to Silverlight.

Silverlight is not video , it can play video...

Trying to convert an swf to flv is similar to converting an exe to flv

ok?

Re: [flexcoders] X-axis values in flex chart

[Sefi Ninio]

Hey.

I ended up calculating the number of tick labels to skip and used the
labelFunction to return the value every calculated value.
This works great - I have a label every 10th value, and all values are
displayed in the chart as they should.
Only problem is that the label font size is still very small (actually, it's
exactly the same size as when all labels are displayed).

I even tried to define horizontalAxisRenderers and in it a custom renderer
with a specified fontSize but tis didn't work either...

Does anyone have any ideas on how this can be accomplished? What I need is
to display every Xth label, with a readable font size...

Thanks,
Sefi

If there are good free tools to do it, why should Adobe bother compeating 
unless it can make a killer advantage.

If people want to go in the direction of spending more money, as opposed to 
less money, they should feel free to do so. We'll see them back again in a 
few years :-)
