I'm seeing this error in my build, anyone know why it could be happening ?
[compc] Loading configuration file /Users/mrinalwadhwa/Projects/Blu/Development/flexsdk/trunk/frameworks/flex-config.xml
[compc] Error: could not find source for class mx.core:DesignLayer in namespace http://ns.adobe.com/mxml/2009.
Did you ever resolve this? I am getting the same thing.
