I am using Spring MVC with hibernate. my Application pojo has a Customer
associated with it. The association is made via a 'customer_fk' column on
the Application table of type int8, which stores the id of the associated
Customer.
when I edit an Application what has a Customer assigned, I get the
following exception
[ismid] ERROR [http-8080-Processor25] OptionsTag.doStartTag(84) |
java.lang.Long cannot be cast to com.ism.ismid.model.Customer
java.lang.ClassCastException: java.lang.Long cannot be cast to
com.ism.ismid.model.Customer
at com.ism.ismid.model.Customer.equals(Customer.java:35)

org.springframework.web.servlet.tags.form.OptionWriter.renderOption(OptionWriter.java:172)
I already have a CustomerEditor which is working when i _create_ an
Application entity with an assigned Customer. This exception occurs when I
try to _edit_ the same entity.
It seems like the CustomerEditor works when creating the Application because
it is being used to deserialise a Customer from customer_id in the form of a
String , but in the Edit case, the Customer needs to be converted from a
Long.
Any ideas?
