Can not open FXML files in DataApp example

Question

Hi,
I download javafx_samples-2_2_0-windows.zip and unzip, and open DataApp project. I build and run, it's ok.
but I cannot open many fxml files, for example, it gives me following error messages:
Error loading file 'C:/work/tianqing/Java/JavaFX/TestProjects/DataApp/DataAppClient/src/com/javafx/experiments/dataapp/client/livetab/live-tab.fxml'.
C:\work\tianqing\Java\JavaFX\TestProjects\DataApp\DataAppClient\src\com\javafx\experiments\dataapp\client\livetab\live-tab.fxml:0: error:
     java.lang.ClassNotFoundException: com.javafx.experiments.dataapp.client.map.UnitedStatesMapPane
Could anybody tell me why?
I'm using Netbeans 7.2 and my java version is "1.7.0_07".
Thanks very much!

Hi,
I believe that's caused by one of the bugs mentioned in SceneBuilder 1.0 release notes. When you open an FXML file that contains custom types - such as com.javafx.experiments.dataapp.client.map.UnitedStatesMapPane, SceneBuilder should popup a dialog window - prompting you to enter a classpath from which to resolve these types. Unfortunately, this popup is not displayed when you open an FXML file from NetBeans or by double clicking on the FXML file from the file system.
Sometimes SceneBuilder will open - but all custom types will be hidden - sometimes you will get a ClassNotFoundException (depending on how the custom type was imported).
Fortunately there's a work around: start SceneBuilder by double clicking on SceneBuider's icon - instead of double clicking on an FXML file. Then use "File > Open..." from within SceneBuilder to open your file.
Hope this helps,
