> Hi
> I still get an NPE whenever I use MessagesDialogExceptionHandler.
> For some reason, may be due to my xml configuration (??), the method afterPropertiesSet is called before ApplicationServicesLocator.services() is fully setup:
> Caused by: java.lang.NullPointerException
>         at org.springframework.richclient.exceptionhandling.AbstractDialogExceptionHandler.afterPropertiesSet(AbstractDialogExceptionHandler.java:51)
>         at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1390)
>         at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1359)
> I am using the sample configuration:
