Connect your BankBizobj and your AccountBizobj with:
def createBizobjs(self):
bankBizobj = BankBizobj(self.Connection)
self.addBizobj(bankBizobj)
accountBizobj = AccountBizobj(self.Connection)
accountBizobj.LinkField = "bank_iid" # foreign key to bank table
bankBizobj.addChild(accountBizobj) # accounts are childs of bank
self.addBizobj(accountBizobj)
The whole linking between banks and accounts is done by Dabo.
There is no need for manual event processing.
