what happens when you click the :P+ when you have a query with parameters for your custom type ?
It should automatically figure out the type.
Hereby you will find all the necessary details for my use case....

I'm trying to execute the following statement in HQL Editor:
Code:
from Statement stt where stt.lastProductionDate = :businessDate
When I click the :P+, HQL Editor displays:
- Name: businessDate
- Type: string
I don't really know if it should display those parameter values or the following ones instead:
- Name: businessDate
- Type: StringDateType
Moreover, what value should I provide to the parameter within HQL Editor ? A java.lang.String or a java.util.Date ?
I've got the same issue with a generic enum UserType.
