I’m playing with Flex data Providers and actually I’m testing ArrayCollection. There are 3 ways to populate an Array collection:
Last technique is (as far I saw) absolutely the fastest , I did a test in which I populated a collection with 300,000 objects and it taken about 9 seconds instead of 32 (350% slower) of first one! The second technique is also faster than the first, but the third is better.
So, what I learned is that addItem() should used only to add few items, instead for huge collection should be avoided in favor of the third technique described in order to obtain better performances.

With Flex Builder is possible to install several SDKs (for example for testing purpose), all the SDKs are available here: http://opensource.adobe.com/wiki/display/flexsdk/Flex+SDK.
It’s possible for example to download the last SDK (still a preview) Flex 4 (codename Gumbo) and add it to the already installed SDKs, the procedure is really simple:
This is how the SDKs window looks on a Mac:

Today I’ve moved my first steps in the Flex world, following the introducing lessons of “Adobe Flex 3 – Training from the source”. After an introduction about RIAs, I’ve met Mr. Flex Builder and he told me about the fact that he has two faces, one for the source code and one for the visual design, and that he can switch among different perspectives (development, debugging and profiling)… then he showed me all his controls and layout components… he was so proud of them, but I told him that I can’t spend all the weekend to test their functionalities. So, I’ve took a look at how layouts work in Flex, and I’m very satisfied about the ability to draw dynamic areas that are able to resize and to be anchored to specific points.
