[flexcoders] Cairngorm and compile time generated errors

[bparvizi1]

I'm using Cairngorm in Flex Builder Eclipse.  However, in my .as and 
mxml files the compile time error checking in the problems panel does 
not work.  Compile time errors fall silent. I made sure to have 
the "Build Automatically" checked as well, so I know I am compiling 
it.  I have to run the app to see the errors.  The little red x does 
not show up next to the code line number.  Code hinting works fine.  
Does anyone know how to fix this? 
Thanks.
