>
> If the logging level is set to debug, the bean utils populate method calls the toString() methods on the  
> state classes during parsing of the dialog configuration file by the digester. This is causes a null  
> pointer exception as the toString() methods call getDialog().getName() and the initialisation of the  
> web application to fail.  
>   
> Affected classes: ActionStateImpl, ViewStateImpl, EndStateImpl  
>   
> The fix is to add a check for null values on the call to getDialog(), i.e.:  
>   
> public String toString() {  
>   
>         return "ActionState[dialog=" + ((getDialog() == null) ? "null" : getDialog().getName()) +  
>                ",name=" + getName() +  
>                ",method=" + getMethod() +  
>                "]";
