Question

In propel 1.3 and 1.4 the following inheritance structure worked fine.

table name="payment_method" baseClass="rwf.lib.SymmetricEncryptedObject"> 
    column name="id" type="INTEGER" required="true" autoIncrement="true" 
primaryKey="true"/> 
    column name="discriminator" type="INTEGER" inheritance="single" 
required="true"> 
      inheritance key="1" class="Card" extends="lib.propel.PaymentMethod"/> 
      inheritance key="2" class="RecurringPaymentMethod" 
extends="lib.propel.PaymentMethod"/> 
      inheritance key="4" class="DirectDebit" 
extend="lib.propel.RecurringPaymentMethod"/> 
      inheritance key="5" class="Cheque" 
extends="lib.propel.PaymentMethod"/> 
      inheritance key="6" class="PayPal" 
extends="lib.propel.PaymentMethod"/> 
      inheritance key="7" class="Moto" extends="lib.propel.PaymentMethod"/> 
    /column> 

However with propel 1.5 when you create a new inheritance say

inheritance key="8" class="RepeatingPayPal" extends="lib.propel.PaymentMethod"/> 

I get the following error

[PHP Error] Argument 1 passed to DataModelBuilder::getNewStubObjectBuilder() 
must be an instance of Table, null given, called in /usr/local/www/ 
/extlib/propel-1.5.2/generator/lib/builder/om/PH P5MultiExtendObjectBuilder.phpon

Now to almost solve this I can remove the lib.propel from the extends
section. but I still get the same error when I create an inheritance
that references an inheritance class ie.

inheritance key="3" class="ContinuousAuthorityCard" 
extends="lib.propel.RecurringPaymentMethod"/> 

(with or without lib.propel)

im not sure if this is a bug or a configuration problem but I cannot find
any docs that deal with the situation. I think I need to be able to state
lib.propel as we have classes in here that we use and also classes with in
another directory called rwf.lib as you can see from the baseClass of the
table pasted above.

Hope someone can point me in the right direction.

Answer 1

So I decided I no longer needed the lib.propel which has got ride of the first problem.

There was second problem I came across with inheritance and this is the bug I have posted http://www.propelorm.org/ticket/1033 if anyone is interested in that.
