For reasons best known to themselves, Adobe do not ship the trial Data Visualisation components with the SDK download, so you have to extract them from the Windows download yourself.
Update Aug. '09:The DV components are now available on their own, with full source and no need for a Builder licence to remove watermarks.
If you need older versions though, you'll still need the below instructions.

First, install the Flex 3 SDK:

If you are playing around with the Linux version of Flex Builder, CFEclipse, or generally mucking about with your Eclipse, or need to upgrade to a new Eclipse version, you've no doubt been annoyed at the way this removes all your carefully installed plug-ins.
Fortunately there is a way to keep them across Eclipse re-installs.

All you need to do is create a few magic directories and one file:

I've been playing with the method that seems to have been hiding from everyone for a while at http://www.briankotek.com/blog/index.cfm/2008/1/28/Returning-Typed-Structs-vs-CFCs-to-Flex
to generate arrays of value objects based on a query, but without using createObject().

There is a problem applying Dell BIOS updates to (at least) the PowerEdge SC440 and SC430 models:

# chmod u+x SC440-010500.BIN
# ./SC440-010500.BIN

Before I get into the meat of using ColdSpring to save even more time (by writing the Service layer for you, believe it or not), I wanted to take time out to give you some 'take home' reading and also address some terminology issues.

Imagine a DataGrid. A DataGrid that is displaying Model.searchResults, but needs to start an effect and reset selectedIndex when the data changes

One approach maybe to follow a pattern than involves having the Command call a method on the View, and this view method takes charge of doing whatever else is needed.
This makes Commands more complicated and means Events have to have an extra 'view' property which is kept in the Command as a private variable.
The View then has to expose a public 'onCommandNameResult' method which the Command calls in onResult().

Having read http://www.adobe.com/devnet/flex/articles/blueprint_02.html[1] I think there is a better way to have the View respond to change in the Model (i.e. Command results) without needing this callback.

Looks like this is your chance to give a bit of direction to Adobe on what you'd like from a ColdFusion coders IDE - take the survey here.

For the record, I plumed for 'free' as 'how much should it cost', but added a note that if the server was free, there was probably a market for an IDE with all the features CFEclipse doesn't have (yet). Competing with free is hard work though, and I'd much rather Adobe just paid people to improve CFEclipse.

I mentioned before ([node:1490]) this was coming but it's online now over at www.bbc.co.uk/iplayer/. And it all seems, as expected, to work very well.
If our V+ PVR ever fails to record something, at least we have a backup.

Oh, you have to (appear to be) in the UK for it to work, on the assumption everyone in the UK has paid the licence fee and no one in the rest of the world has.

One of the reasons I love Builder (apart from CTRL-O and CTRL-SHIFT-R) is that I've actually managed to make the new RSL cache feature of Flash Player work, when previously I'd failed totally to do it using the free command line SDK compiler.

Taking the instructions from Adobe's RSL cache wiki entry, it was a simple matter to go through and set the Framework, RPC and DataVisualization libraries to be RSL .swz and .swf files.
