Solved, though not sure why! I include it here for completness, in the hope it may help someone else.
I gave up trying to get the icons displaying and went ahead and created PNGs, then added the first of them using the icon tag of ButtonIcon (icon="assets/icons/ico1.png") leaving the FontAwesome assignment still there under iconFont. When I went to test it, the original FontAwesome icon was displaying instead of my icon :D No idea what was causing that, but now it works so Ill take it! -- View this message in context: http://apache-flex-development.2333347.n4.nabble.com/FontAwesome-and-Flex-4-14-tp46092p46097.html Sent from the Apache Flex Development mailing list archive at Nabble.com.
