There is a two-day training workshop taking place on the 24th and 25th of September in London covering some of the more advanced topics relating to Flex development.
If you’ve been working with Flex for a while and are interested in the differences between MVC Flex frameworks, design patterns, application builds and continuous integration, portals, modularization of Flex applications, unit, stress & functional testing, as well as a host of other topics, then I’d encourage you to check out this workshop.
More details and pricing information is here. You can use the code ‘ebd’ to get a 20% discount on the course fee.
