I am trying to perform a toArray() on a retrieved Set:
Code:
public void validateBeneficiaries(BeneficiaryDesignation designation,
Errors errors) {
Beneficiary[] beneficiaries = (Beneficiary[]) designation.getBeneficiaries().toArray();
...
}
If I inspect designation.getBeneficiaries() I see the following:
Quote:
designation.getBeneficiaries()=PersistentSet (id=128)
If I inspect designation.getBeneficiaries().toArray() I see the following:
Quote:
designation.getBeneficiaries().toArray()=Object[4] (id=168)
When I drill into that array I see an array of Beneficiary of length 4.
Why then am I receiving a cast exception when I call the above code? Am I overlooking something obvious?
Thanks,
Leo
