I think you're correct, Tom, on the functionality. According to the FS "A particular fee instance can be applied multiple times to a customer account". Checking out this functionality in the product also verifies this behavior. I can create a loan account with two of the same fee type applied to the account. ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom Bostelmann Sent: Thursday, November 22, 2007 5:01 AM To: Developer Subject: Re: [Mifos-developer] issue 1512 persistent object equals/hashCode- data model clarification needed This is a great question. The additional test fails - which it should because LoanOfferingFeesEntity (bad use of plural 'Fees' in name aside) represents an instance of a fee that is associated with the loan product. Here's my attempt at a business example (Aliya/Emily/Beth/Amy/... please step in to correct me if I'm wrong): An example situation could be where the loan officer sets up a fee to cover the costs of providing a consultation visit (this is represented by the FeeBO). The loan officer has decided that a certain loan product requires two such visits (two instances of LoanOfferingFeesEntity using the same FeeBO). Therefore there should be two different instances of the same fee associated with this loan product. Does that make sense?

To ensure I understand the business requirement / data model, could someone clarify whether the following is true or not? 1. For each loan product, it may be associated with multiple fees. (I guess fees the product could apply) 2. However, each loan product will be associated with the same fee at most once. In other words, in mysql, table prd_offering_fees should have a unique constraint on (prd_offering_id, fee_id) You can also see the attached patch on LoanOfferingBOTest that reflects the above assumption. Or you can see the actual test right below (rather than going through the patching). - sam A new test method in LoanOfferingBOTest.java (equivalent to the attached patch) public void testBuildloanOfferingWithDuplicateFeeXXX() throws SystemException, ApplicationException { createIntitalObjects(); Date startDate = offSetCurrentDate(0); LoanOfferingBO loanOffering = new LoanOfferingBO(TestObjectFactory .getContext(), "Loan Offering", "LOAN", productCategory, prdApplicableMaster, startDate, interestTypes, new Money("1000"), new Money("3000"), 12.0, 2.0, 3.0, (short) 20, (short) 1, (short) 12, false, true, false, frequency, principalglCodeEntity, intglCodeEntity); FeeBO fee = TestObjectFactory.createOneTimeAmountFee("Loan One time ", FeeCategory.LOAN, "100", FeePayment.UPFRONT); LoanOfferingFeesEntity loanOfferingFees1 = new LoanOfferingFeesEntity(loanOffering, fee); loanOffering.addPrdOfferingFee(loanOfferingFees1); // another fee for the proudct: which refers to the same fee // as the one above LoanOfferingFeesEntity loanOfferingFees2 = new LoanOfferingFeesEntity(loanOffering, fee); loanOffering.addPrdOfferingFee (loanOfferingFees2); assertEquals("sam: I believe the business requirement is that the loan should not have fees that are essentially the same.", 1, loanOffering.getLoanOfferingFees ().size()); assertEquals("sam: I belive these two offering fees are considered identical from business requirement", true, loanOfferingFees1.equals(loanOfferingFees2)); } ------------------------------------------------------------------------ - This SF.net email is sponsored by: Splunk Inc.
