Author: ed
Changed:
U trunk/dabo/biz/dBizobj.py
U trunk/dabo/db/dCursorMixin.py
U trunk/dabo/db/dDataSet.py
Log:
Added references to the bizobj and cursor that \'own\' a data set. This will enable you to write replace() statements using functions such as \'self.Bizobj.foo(myField)\', where \'foo\' is a method of the bizobj.
