ADF provides the chance to create Custom, Validated Data Types by using Domains to define fields in Entity Objects as described in

4.15.1 How to Create a Domain

 

However in ADF 12.2.1.2.0, especially with dynamic components, an exception similar to the following is thrown while creating a Business Domain Layer Using Entity Objects:

 

where <CustomDomain> is the full classpath of the class representing the defined custom domain.

 

For a common JSF page a workaround is to set the converter of an af:inputText from "default" to "oracle.genericDomain" in the component Properties.
However, in case of a dynamic JSF page using af:dynamicComponent such workaround does not work.
