Cannot load custom control sample from FXML Documentation

This was reported to the documentation group by a user.
The custom_control.fxml file (attached) which is used in the "Mastering FXML" tutorial <http://docs.oracle.com/javafx/2/fxml_get_started/custom_control.htm>
 can be loaded by SB 1.1, but not by SB 2.0.

When trying to show details on the load error dialog, I get the following trace:

loader.getController()=com.oracle.javafx.scenebuilder.kit.editor.panel.util.dialog.TextViewDialog@258860fc
loader.getLocation()=jar:file:/Users/svienot/Projects/sb20/SceneBuilderKit/dist/SceneBuilderKit.jar!/com/oracle/javafx/scenebuilder/kit/editor/panel/util/dialog/AbstractModalDialogM.fxml
