JavaFX 8 'fx:constant' causes a parse error in Eclipse

Question

I am trying to load in FXML for my JavaFX application and am receiving this exception:

Caused by: javafx.fxml.LoadException:

Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[52,37]

The FXML lines causing this are:

<cursor>
    <Cursor fx:constant="DEFAULT" />
</cursor>
<columnResizePolicy>
    <TableView fx:constant="CONSTRAINED_RESIZE_POLICY" />
</columnResizePolicy>

I am using JavaFX 8 in Eclipse Neon with the e(fx)clipse plugin.
Thank you if you can help.

Have you added the namespace declaration? Please show the root element of the fxml file. — fabian, Sep 13 '16 at 18:54
Wow that fixed it, thanks @fabian. For people coming with the same problem: I added `xmlns="http://javafx.com/javafx/8.0.65" xmlns:fx="http://javafx.com/fxml/1"` to my root element. — learner0000, Sep 13 '16 at 19:01

I had forgotten to add the proper namespace to my root element.

xmlns="http://javafx.com/javafx/8.0.65" xmlns:fx="http://javafx.com/fxml/1" add those to your root and this is solved.
