The main issues with FX are the same as those people have with ActionScript. The language is reasonable as a scripting language to tie things together but it feels very odd for most Java developers. Unlike action script you don't get the advantage of the amazing GUI tools Adobe offers.
Web start seems simple when creating hello world, NetBeans gets you started with a self signed JWS version. For production you will need a proper certificate which is harder but doable. Then there is the issue of pack.gz with its odd special case servlet (don't get me started on that one). Then you have the issues of HTTPs deployments not working for some people and the multiple incompatibilities between JWS versions installed which occur when someone has a corporate PC with a specific version of Java installed.
There are lots of issues some summed up here for older versions:

Newer versions of JWS (Java 6u10) broke different things but didn't really fix lots of the long standing issues. Most people using JWS just got burned one time too many.
