And besides that I really can’t understand how those parsely components work … please someone help !!

It’s been a while since you wrote this, but I still want to thank you: this is HUGE for anyone looking to optimize an ADG’s performance – we were desperate until we found your article. Quick question, related to the same topic: do you have any ideas on how to optimize an ADG for insertion of data? Basically, when we add a new row the ADG takes over the CPU and responds super slowly – some sort of optimization is even more desperately needed in that case.
I tried the same trick by ignoring CollectionEvent events of kind “add” and saw a little improvement, but not quite as dramatic as what I saw with your example. Would love to know what your thoughts are on handling such a case.
thank you!

This LCDS stuff is great but I can no longer afford it. For years, I’ve been touting Adobe as -the- technology to go to, and look at my thanks $30K per CPU. Think I can deploy my own app on this new technology? No way.

I may be forced to abandon my zeal for the platform and dreams of true RAD development. I miss the days of fat clients back in the 90′s and RAD development with Delphi – we were very productive back then! Thought Adobe was bringing the really cool stuff to us again, but some @%#%#! marketing folks must have changed course.

As a small business owner, I feel screwed royally, and I wonder what Adobe is thinking?

Thanks

Also, you need to grab fds_rb.swc and fds.swc from lcds resources directory and put them in your referenced libraries for TraderDesktop-lib. Otherwise, it won’t deploy any changes as you will have compile errors…

Never got the sample to work, had to get the source code. Had to change the Flex Compiler from Air beta 2 to “use default SDK” in Flash Builder (right click on the project then Properties/Flex Compiler. Also, you need to rename or copy channels-config.xml to just config.xml. It’ll still give compiler errors for the TraderDesktop-lib but just ignore them and it will finally work. Fun…

I finally got past that (wasn’t loading channels-config.xml properly, was looking for config.xml in same directory) but now says – Error: Unsatisfied dependency: Context does not contain an object of type mx.rpc.remoting::RemoteObject.

Googling around isn’t shedding much light either.

Sorry to be a bother…

Trying to get this to work and encountering an error. I fully admit I’m a Flash/Flex newbie so it’s probably something simple but I’ve not had any luck so far.

Can you help because I’m VERY interested in using Flex in a real-time/heavy-data application. Thanks for any assistance you can give me…

When I load the page I get the following error in flash debugger:
