Simple calculations or formatting of existing fields. For example, say my bizobj is invoice line items with fields cDescription, nQty, and nPriceEach. I may have the following virtual fields: nLineAmount : nQty * nPriceEach cQtyPriceString : "%f @ $%.2f" % (nQty, nPriceEach) Otherwise, you'd be tempted to put such calculations in the UI layer where you are actually using them, when they really do belong in the biz layer, defined once. You can sort on virtual fields, bind to virtual fields, do anything you can do with regular fields (except save values back to them). -- pkm ~ http://paulmcnett.com _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/dabo-users Searchable Archives: http://leafe.com/archives/search/dabo-users This message: http://leafe.com/archives/byMID/dabo-users/[EMAIL PROTECTED]
