Just instantiate more than one instance of the bizobj, and work with
them independently. You'll have to give them unique DataSource
properties, however, so that dForm doesn't get confused. Example:
{{{
from bizcats import BizCats
class MyForm(dabo.ui.dForm):
def afterInit(self):
app = self.Application
self.bizCatsAll = BizCats(app.dbConnection, DataSource="cats_all")
self.bizCatsSome = BizCats(app.dbConnection, DataSource="cats_some")
self.addBizobj(self.bizCatsAll)
self.addBizobj(self.bizCatsSome)
}}}
Now, set the DataSources of your 2 grids appropriately.
