I've done some further debugging and here's what I now know: 1. I was able to bind TypeConverters to the model.group and model.selectedNutrients properties by creating a SimpleFoodCreationRequest-conversion.properties with the following lines:
group=com.opensymphony.xwork2.util.EnumTypeConverter selectedNutrients=com.opensymphony.xwork2.util.EnumTypeConverter Element_selectedNutrients=com.gb1.healthcheck.domain.nutrition.Nutrient So converters can be defined at the nested object's level. 2. The group property is correctly mapped, the conversion being done by the EnumTypeConverter. 3. The selectedNutrients property is still not being mapped correctly. The EnumTypeConverter is invoked to map the whole parameter array ([VITAMIN_A, VITAMIN_B]) to an instance of Nutrient[]. To do this, it arbitrarly chooses the first parameter (parameters[0] => VITAMIN_A) and tries to map it by calling Enum.valueOf(Nutrient[].class, "VITAMIN_A"). This obviously fails. Why doesn't Struts2 / XWork recognize that there are multiple parameters to be mapped to multiple enums and call the EnumTypeConverter for each of them, sending the resulting Nutrient[] to the request object? Do I need to specify something else?
