I am not able to use groovy script files (via <fx:script source="TestControl.groovy"/>). I get the following exception:

I guess its just an "extension detection"-problem... embedded scripts like the following do work fine.

<Button fx:id="buttonTest" text="Test Button" onAction="inputTest1.text = &quot;test&quot;"/>
