The Fattest

I just took the entire tutorial, step by step and it worked just fine. I am using Xcode 3.2.1 and iPhone SDK 3.1.3. I did update a couple things in the tutorial to make even easier to follow. Couple items to make sure you did/do are make sure the file owner is set inside of Interface Builder and make sure that you imported the "SimpleUIViewController.h" inside of the app delegate file. I'm sorry you had issues but I promise that it did and still does produce a working application. :)

What has changed? I work with XCode everyday and nothing noticeably has changed for me.

Yeah it works like like any other Flex application. Remember you need to have a Flex Builder Professional for charts, but as long as you have that it shouldn't be an issue.

All this sounds like you need to build a custom item renderer for certain columns. The advanced datagrid may handle what your looking to do with the multiple rows. You can check out a basic tutorial on item renderers here on the site, http://www.switchonthecode.com/tutorials/flex-using-item-renderers.

How large is the set of data? Also what does the code for the datagrid look like?

In order to use something like this in Flex on the web you would have to have the server handle creating the file for download.

Yep, nice catch. Updating now.

Yeah I really hope to get one out here soon. We have had some hiccups in all kinds of things.

The issue that flash is single threaded. What you can do is break it up and throw a set timeout in there to show some progress.

Thanks, fixed.
