Join David Gassner for an in-depth discussion in this video Displaying data with List and IconItemRenderer, part of Flash Builder 4.5 and Flex 4.5 New Features.
When you're working with complex data in a Flex mobile application, you can work…with it in exactly the same way, as we would in a web-based or a desktop…application: using remote object or web service or HTTP service components to…retrieve data and then visual components to display it.…I'll show you how to use these visual components that are included with Flex…4.5, using a version of the application called DataLists.…I'll start by retrieving and reading the data into memory.…The application already has an XML file called tours.xml.…
I'll look at that with the Eclipse text editor and show that each tour element…has properties called tourName, price, duration, and image.…Returning to the component, I'm going to copy in some code that will retrieve…the contents of the XML file and transform it into an array collection.…Down towards the bottom of the project in the root folder, there is a file…called typinghelp.txt.…It has a script element with a bunch of ActionScript code and an HTTP service…

Q: Is Flash Builder compatible with Mac OS X 10.7 (Lion)?
Q: I'm using the most recent versions of Flash Builder and Flex. The projects provided in this course's exercise files don't run correctly. How do I get the code working?
A: The course's exercise files were built for the original release of Flash Builder and Flex 4.5. There are two potential issues: the version of the Flex SDK linked into each project and the version of Flash Player you have installed on your system.
For each project, follow these steps after importing it into Flash Builder:
- In the Package Explorer view, right-click on the project name and choose Properties.
- Click Flex Compiler.
- Change the Flex SDK Version to Use default SDK.
- Click OK.
- The project should now compile correctly.
- Open Windows Explorer (Windows) or Finder (Mac).
- Navigate to the Flash Player installation folder.
- Open the player subfolder.
- Open the subfolder for your operating system (Mac or Windows).
- Open the version subfolder.
- If running on Mac, open the DMG file and install the Flash Player application.
- If running on Windows, run the Flash Player installer executable for whichever browser you use for previewing Flex applications.
