   I am kind of new with Flex 3.2, but I wanted to try the Flint engine.
   
   I downloaded 2.01, and imported this in a new Flex 3 project.
   
   I add the code from the Examples, and there are no errors. But when I run the app:
   
   TypeError: Error #1034: Type Coercion failed: cannot convert org.flintparticles.twoD.renderers::DisplayObjectRenderer@5e1e3a1 to mx.core.IUIComponent.

   Not sure what this means, and how I can solve this?
   
   Thanks!

   Flex's layout system only works with displayObjects that implement the IUIComponent class. Since DisplayObjectRenderer doesn't implement this class, Flex throws this error. To fix it, you need to wrap the renderer in an object that does implement IUIComponent - Grant Skinner has an example of such a wrapper here.
   
   I'm currently developing a Flex friendly version of Flint, to be part of the 2.1 release. It's in the flex branch of the svn repository.

   Perfect, this worked like a charm!
   
   I wasn't aware of this 'limitation'. Looking forward to 2.1 stable!
