Comment 5 Chiana 2013-09-29 01:14:34 UTC 
It seems this is related to the xmlns:fx="http://javafx.com/fxml/1" parameter that is set, that makes to not work properly, if you then add "xmlns:fx="http://javafx.com/fxml" this error occurs, if you on the other hand remove the "/1" from the xmlns:fx..." line it seems to work...
Comment 6 Lou Dasaro 2013-09-29 06:02:30 UTC 
This exception likely a result of trying to redefine namespace xmlns:fx, e.g. xmlns:fx="http://javafx.com/fxml/1" xmlns:fx="http://javafx.com/javafx". 
I copied that into my FXMLDocument.fxml and quickly received an Exception.

For the workaround, you should delete one of the xmlns:fx declarations - but bear in mind that each time you save the file in Scene Builder, it will update the namespaces as follows (using Scene Builder 1.1 GA, which correctly injects): 
xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2"

See also bug 236509 and included JavaFX RT and Scene Builder JIRAs.
Comment 7 Svata Dedic 2013-09-29 16:45:56 UTC 
will be fixed soon for dev/8.0
Comment 8 Svata Dedic 2013-10-02 08:39:29 UTC 
Actually a separate defect, even with improved namespace support. Note you cannot have two xmlns attributes, it's a XML level error. 

Fixed in rev http://hg.netbeans.org/jet-main/rev/05316f8cbcef
