[flexcoders] Re: horizontal DG

[tntomek]

I think you can use lockedColumn to simulate the grid header on y axis. Then 
programmatically add n-columns. Note that there are performance considerations 
for having a very wide grid, its certainly not as fast as default setup. You 
will also need a dataprovider that you can map column data fields on. If you 
are using objects you will need to use Proxy, XML might just work by default

Re: [flexcoders] Label help

[Alex Harui]

The truncation algorithm simply chops characters until textWidth + 
truncationText.textWidth fits.

You could write a similar algorithm that adds “.” until you reach the desired 
width.  Could be slow though.  There are variants that use binary-subdivision 
to speed things up a bit, but it is still essentially looping.

An alternative would be to always have a row of “.” as wide as the renderer and 
overlay the two text pieces over the row and use some white backgrounds behind 
the text so it covers the “.”  That could be faster, and the “.”would always 
line up in the rows above and below, but the distance between the last char and 
first “.” would vary.

In mx components, there is a Label component and a UITextFIeld that is usually 
used to display text in various components.  In Spark, there is just Label so 
there would be less confusion about which one to use where, especially for less 
tech-savvy folks like skin designers using Flash Catalyst.  Lots of folks use 
mx:Label in item renderers and pay the performance cost and have the same issue 
with styles.  And now that Spark Label is everywhere, if you change its default 
styles the effects show up everywhere.  Which is normally a good thing.  And 
the way to get a subset of Labels to behave differently has not changed.  Use 
CSS via a class selector and stylename, or subclass and use a custom 
type-selector.

I am using Spark Label Components, which matters because I can't change the

[flexcoders] Re: Pb with mx:image and Path on server

[Flex]

It looks like you are using ../ which means go up one directory and based on 
what you describe for you app structure that is not true, since Images folder 
is a subdirectory of your swf root.

Try this..


also ensure that your directory name starts with an uppercase on the webserver. 
Best not to mix case especially on Unix/Linux systems.

Did you try using an absolute URL for server file upload url as opposed to 
relative paths? I am not sure what url you are loading the module from relative

You shouldn't need to do this.  Try setting the minimum and maximum values on 
the date time axis to the desired dates and it should do the rest(regardless of 
which dates there are data for).

Re: [flexcoders] Component Data Calls

[Flex]

We hit a number of issues using modules as well. Pretty much most of them had 
to do with modules loading resources before the main app so that raised issues 
with main app or other modules trying to use them...not all resources had the 
issue and it became a guessing game of putting dummy vars etc in the main app 
so we gavce up. A pity since other than that we even got the back browser 
button to work with modules.

We are hoping that Flex 4 will make it work better. Don't get me worng...I am 
not criticizing Flex in any way but it is just not easy to use Modules AND it 
does seem to have issues based on our experience.

Anyone.
When you install LCDS, you'll pick a J2EE install (not tomcat). The jars 
you need will be under the path that was mentioned "/resources/lib/".


Regarding the license, you need to be sure that you cannot have LCDS 
container accessing more than 1 CPU with maximum 2 cores. The best to 
get the better performance is to deploy LCDS ouside CF so your CF 
instance can fully take advantage of the machine and only LCDS will be 
limited.

Re: [flexcoders] Flex and LCDS - Cannot Remove Client?

[Jeffrey Vroom]

LCDS maintains several data structures on the server to track clients using
the messaging system.   The standard HttpSession is kept by the app server
using the cookie.  The FlexClient is associated with an individual Flash
player instance.  Each subscription has a corresponding MessageClient to
track that subscription.   I think this error occurs when the client is
trying to send a message to the server to clean up that flex client data
structure.   It might be occurring though when a session is expiring or
something.  I'd expect to see this type of thing if you restart a server or
are using non-sticky load balancing - so the HttpSession and FlexClient
states get out of sync.  It may well not be a problem but might cause a
memory leak or something like that.

If you want to track it down further, turning on the debug logs for some of
the categories would show you the context in which it is happening.

Re: [flexcoders] Bitmap width/height 0 when loading image from hard drive

[Alex Harui]

IMHO, the player and the hosting browser get really unpredictable once you get 
past 500MB or so.  Hopefully you’ll be able to stay below that and your app 
will be stable.

Thanks Alex for the follow-up.  Your questions prompted me to dig into the 
memory load more and it looks like we had some bad memory issues.  
Specifically, when the user selects a bunch of photos, we load those images in 
using file.load() and then generate small thumbnails from the loaded data.  The 
problem was we were keeping around the file references while the files were 
also being uploaded. The full file data (stored in the data property on 
FileReference) was no longer needed in the app after the thumbnail was 
generated but we were hanging onto it anyway.  By calling file.data.clear() 
after generating each thumbnail we were able to free up that memory...which was 
a LOT of memory.

So, the short story is there DOES seem to be some funky business in Loader when 
Flash Player is under a lot of memory stress.  On the flip side we've reduced 
the memory stress sufficiently to hopefully not run into the issue in the first 
place.  To answer your questions anyway:

The process memory was up around 1 GB before we starting running into trouble 
(with proper memory cleanup this is dramatically lower).  This is on a 4 GB 
memory Windows Vista machine and I had quite a few other applications open 
(Flex Builder, Illustrator, etc.)

I had loaded in 450 images with each being roughly 1.5 MB each as compressed 
JPGs and we were creating thumbnails at about 150x100 pixels each (~60k in 
BitmapData each or ~27MB for 450 thumbnails).  Reports from other people show 
they were getting problems with less than 200 images but we haven't dug into 
the details of the size of their images, etc.

In our test, all 450 thumbnails were still around which took up around 27 MB.  
And, because of improper memory cleanup, 450 full bitmaps loaded from the hard 
drive were still in memory also.

Thanks for the help.  Hopefully that will clear up our problems.

And yet another update.  Sorry for the large number of emails.  It looks like

24 million pixels just fine.  As I add more stress and then attempt to load the

adding stress to the Flash Player and I continue to load the same 14 million 
pixel image I'll start to get 0 width and height for that image, even if it's 
under the bitmap limits.  At that point I can load a 12 million pixel image 
fine.  If I continue to use the app and add stress, I'll soon not be not even 
be able to load the same 12 million pixel image.  This imaginary limit seems to 
get smaller and smaller over time and has very little, if anything, to do with 
Flash's max bitmap dimensions.

[flexcoders] Partial LineSeries - is it possible?

[Battershall, Jeff]

I have a line chart with a DateTimeAxis that is stipulated to be about 750 
pixels wide and it's used to display a decade's worth of data points.  However, 
in the current decade, there are only a couple month's worth of data points.  
As a result the line series takes up the entire chart's entire available 
horizontal space.  What I'd LIKE to have happen is have the line series only as 
wide as the data points require - kind of like a YTD graph.  See what I'm 
getting at?

The Spring bean which is exposed as a Remote Object has the following method

I am unable to understand why AMF Channel or Blaze DS is treating the String as 
HashMap !!!

 

This was working pefectly fine till yesterday !!

 

The version of the BlazeDS i am using is : blazeds_turnkey_3-0-0-544

and the Flex SDK Version is : flex_sdk_3.5.0.12683

 

We recently upgraded to Flex 3.5.0 version earlier we were using 3.3 version

[flexcoders] headerRenderer ComboBox

Hi,

Today, my question is : How to populate a ComboBox (as headerRender of an 
AdvanceDataGrid) with the rows of the corresponding column?

(and doing it inside of my custom ComboHeaderRenderer AS3 class to get 
something as generic as possible)

I saw a lot of samples of ComboHeader everywhere, but always filled with static 
data or in mxml style..

Is a non-visual component that you instruct it to fetch something and the

[flexcoders] Re: Security issues SOLVED. (Mostly...)

[Laurence]

Ok, then...  Fantastic.  I am using AMF to communicate with the CFC's, and I'm 
using the SecureColdFusion channel I created to transfer the secure stuff, and 
the regular ColdFusion channel to transfer the non-secure stuff...  So even if 
I serve the .SWF over HTTPS, nothing will change (except I won't need to set 
'secure="false"' in my crossdomain.xml file.)  Perfect.

So far, the only major differences I've noticed between CF8 and CF9 are the 
configurations of the channels themselves.  I found a comparison in this 
article: 
http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WS5B9C73A8-5FA2-4a54-B0C6-CECA2E20052D.html

That, and the fact that my un-patched CF 8.01 server didn't enforce the 
"public" vs. "remote" policies on the functions in my .CFC's.  I've checked all 
my CFC functions to ensure that they have 'access="remote"' set in the 
 declaration.  Other than that, I've made no changes to my .CFCs, 
and they work fine with CF9.

But I've only been running CF9 for about a week or so?  I'm sure I'll notice 
other differences as time goes on.  But, so far, the transition to CF9 really 
hasn't been all THAT bad.  Just gotta make sure you specify CF9 when you're 
asking for advice -- that was my earlier mistake, assuming CF8 and CF9 were 
more similar than they actually are.

Best of luck in your transition.  Hope my experience helps you to avoid a 
couple of the pitfalls I fell into.  :-)

Re: [flexcoders] Re: Security issues SOLVED. (Mostly...)

[Warren]

It depends on how you are communicating with the CFC.

If you are using the remoting protocols, then how those channels are configured 
is what counts.  Just because the swf is served thru HTTPS doesn't mean your 
data will be IF you are using the AMF channels.  I have used (in test) https 
channels under an http web server. If you want secure data transmission under 
AMF then you need to create and use a secure channel.  

If you are using other means (wsdl, URL, parameters, etc.) to move data back 
and forth, then the web server protocol comes into play.

It would be nice for someone from Adobe to comment on this, especially with 
some sort of overview of the differences between CF8 and CF9.  I'm going to 
have to move soon to CF9 and you've already found one difference in the 
services-conf.xml file (the endpoints) that I'm going to have to deal with.

I don't agree. I use modules extensively and have not experienced any bugs with 
them. It is more likely to be the code you use to load them and what you do 
inside them.

I don't use HTTPS here (We have a closed intranet) so I can't test if it would 
work but as I understand it, you should be able to do an HTTP call from the SWF.

I suggest giving it a try and monitoring the exchange with something like 
Charles. That should tell you pretty quickly whether you can even do it.

[flexcoders] Flex and LCDS - Cannot Remove Client?

[headj...@bellsouth.net]

I am using Flex 3.4/Hibernate/ and LCDS 2.6 with polling AMF running on Tomcat 
5.5 The application works fine, but occasionally I get a message in the logs 
that says "[ERROR] [Service.Message] Failed to remove client: 
884EDC33-A098-231E-44AD-F76A5A6E1A76}" .  (The session ID changes obviously.)

I've looked for information on this message in an attempt to diagnose what it 
is, but haven't found anything on it.  Has anyone else run into this message or 
does anyone know anything about what this means? 

I'm also wondering if this might have something to due with network 
performance.  Does anyone have any pointers for tuning and setting parameters?  
This is not a large application, but our network does suffer from some 
congestion issues and RTMP is not an option due to firewalls.  Could that 
message above be related to poor network performance?

Disclaimer:  I'm new to LCDS, so bear with me!  

Thanks,
JB

This is great, thanks for the links, I'm using FlexFormatter and that's
awesome.

PMD could be what I'm after, I want to remove dead code and Class files and
thanks for the tip on CPD.


?What is TDD?


Thanks!

Re: [flexcoders] Flex 3 + Colfusion + LCDS 2.6.1 manual installation

[João Fernandes]

Jochem, the express license is for LCDS and it's valid no matter you 
deploy it standalone or with CF so you can use Express version (2.6.x) 
with CF9. The main reason why the CF team stop bundle it with the 
installer is the fact the new LCDS doesn't provide an express version, 
so they prefered to bundle BlazeDS instead and provide a readme for a 
manual installation.

I don't think so. With CF 8 you got a license for LCDS Express, but
IIRC with CF 9 you don't.
