问题 For my project i want to implement a combobox with h:selectOneMenu . I read many posts about how to handle the selectOneMenu properly and how to implement a custom converter. The combobox shall store the ID ( Long ) from a different DB Table (named fk_ID) for which a constrain is in place. So far everything seems to function as planned.
