Hi everyone,
I have run out of ideas. I am creating JSR-168 portlets with Spring and Hibernate. In my portlets, I have:
Class:
VendorContactBean (extends ContactBean)
and
VendorCompanyBean (extends CompanyBean)
In the ContactBean class, I have getter/setter methods:
public Set getCompanies()
public void setCompanies()
I have the same thing in my ContactBean class.
The problem is that when I try to add to the existing Set of companies (or contacts) I get a ClassCastException. If I only use the base class ContactBean/CompanyBean everywhere, then it works fine. It's only when I extend the base class do I get this error.
Can someone help me figure out what I'm doing wrong?
Thanks,
Eric
