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! f Cristophe

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? This LCDS stuff is great but I can no longer afford it.

Otherwise, it won't deploy any changes as you will have compile errors...

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... :-) Never got the sample to work, had to get the source code.

Googling around isn't shedding much light either. Sorry to be a bother...
