BeanfieldGroup error Indicator


I’m new to Vaadin and trying to get some error handling on a view with a BeanFieldGroup.
After clicked the “save” Button the BeanfieldGroup commit.
If the Backend throws a RuntimeException now while setting a attribute, the invalid Field shows a Error Indicator(triangle) with the Stacktrace and not the Message of the RuntimeException.

How can i show the Message of the RuntimeException?
