Opening a Java SE project in the GUI Builder view, when the project was previously saved under NB 7.1 OS X version, gives a box titled "Warning - Form Loaded With Errors" and listing a number of JLabels for which generated code sets the FocusTraversalKeysEnabled property. Next to each such JLabel listing is a message that says "Error in loading component property: [JLabel name]-> FocusTraversalKeysEnabled No such property exists in the component." The box recommends opening the form as view only. The editor allows setting the property; however, the property does not appear in the GUI Builder Properties dialog for JLabels, as it does in the OS X version.
