>                 Key: CAY-1196
>                 URL: https://issues.apache.org/cayenne/browse/CAY-1196
>             Project: Cayenne
>          Issue Type: Bug
>          Components: CayenneModeler GUI
>    Affects Versions: 3.0M5
>         Environment: Ubuntu Linux
>            Reporter: Michael Shea
>            Assignee: Robert Zeigler
>            Priority: Minor
>
> To duplicate:
> 1. Open an existing project with the Cayenne Modeler.
> 2. Select an existing attribute on an existing object entity. Delete the Java Type field.
> 3. Navigate to some other object entity.
> 4. Go back to the original one and click the "attributes" tab. You will see that the GUI doesn't get updated when you switch to that tab.
> It looks like the modeler is calling Class.forName( "" ).
> I have managed to work around this by manually editing the map.xml file and filling in a valid java classname for the attribute in question.
> The following stacktrace is printed to the console:
