Eclipse plugin for JavaFX Script

In addition to the support for JavaFX Script in the NetBeans IDE, there is also an Eclipse plugin. Developers can now kick the tires of this new extension of the Java platform in their favorite IDE. At a glance the Eclipse plugin is not as sophisticated as the NetBeans one, however the deployment support is invaluable. One can build and application and just before deploying it, can choose to do this in the browser, desktop or the mobile emulator. 

Users should download the official documentation. More advanced users could use the instructions below:

I followed the instructions about, even including installing Eclipse for JEE, even though I already had Eclipse installed. I do not see the JavaFX menu item. I verified that the new flies are in the ECLIPSE_ROOT/plugins and ECLIPSE_ROOT/features.

I am running on Mac OSX 10.5.x. Any suggestions?

I tried installing the eclipse plugin for JavaFX under windows xp, eclipse 3.4, Javafx sdk 1.1.

Unfortunately it makes the Eclipse help system crash !! It works again if I remove the JavaFX plugin.

I also noticed that it highlighted some errors that were not errors in scripts (i.e. they still build and ran).

This is a shame. I guess it's early days for this eclipse plugins or perhaps it's not compatible with some others.
