Calling Add on a Business Object

The CurrentRow for table '[dbo].[ProdWOEquipment]' could not be evaluated because the CurrentRowIndex is out of range. Business object record count: 0. CurrentRowIndex: -1. Here is the call stack: > MicroFour StrataFrame Business.dll!MicroFour.StrataFrame.Business.BusinessLayer.get_CurrentRow() Line 1790 Basic AspireModel.dll!Aspire.Model.ProductionWorkOrderEquipmentBO.createby.set(int value = 1) Line 419 + 0x8 bytes C# AspireModel.dll!Aspire.Model.ProductionWorkOrderEquipmentBO.ProductionWorkOrderEquipmentBO_SetDefaultValues() Line 77 + 0x1c bytes C# MicroFour StrataFrame Business.dll!MicroFour.StrataFrame.Business.BusinessLayer.raise_SetDefaultValues() Line 1662 + 0xe bytes Basic MicroFour StrataFrame Business.dll!MicroFour.StrataFrame.Business.BusinessLayer.OnSetDefaultValues() Line 1673 + 0xa bytes Basic MicroFour StrataFrame Business.dll!MicroFour.StrataFrame.Business.BusinessLayer.NewRow() Line 6047 + 0xb bytes Basic MicroFour StrataFrame Business.dll!MicroFour.StrataFrame.Business.BusinessLayer.Add(Boolean CheckSecurity = True) Line 7283 + 0xa bytes Basic MicroFour StrataFrame Business.dll!MicroFour.StrataFrame.Business.BusinessLayer.Add() Line 7254 + 0xf bytes Basic The odd things is that I use the same kind of code elsewhere and it runs beautifully. There is something different about this BO's class. I am just not seeing it. I'll keep looking, but if anyone has some tips or tricks to share, I'd appreciate it. Bill

Try setting a break point in SetDefaultValues and step through until you get the error. Set a watch on the current row index. The light bulbs gone off for me many times by just doing that.

If I comment out the default values, the Add() command still ends up bombing on the get_CurrentRow() method of the BusinessLayer. For some reason the BO is not making a new row in the data table. I will keep testing...maybe a light bulb will go off for me, too.

E Group: StrataFrame Users Posts: 2.4K, Visits: 23K	Bill Cunnien (10/24/2008) Does this mean anything? _COMPlusExceptionCode = -532459699 This is form google: _COMPlusExceptionCode = -532459699 this error usally occurs when sql connection timeout or if the sql server is down. i got the same error when i tried to access the webservice which is located in another webserver. (That webserver was down at that time). Maybe you need to close VS and test again. Edhy Rijo

Other similar classes and BOs work just fine (all other applications are hitting the DB without issues). I'll take a closer look at the parent-child relationship. Thanks! Bill

E Group: StrataFrame Users Posts: 2.4K, Visits: 23K	Ok, I found my notes I am calling a child form from a listview, in the childform.Load() I did the following: ' Force the BO assignment here to fix a problem of the BO.Add() not working properly. Me.lstItemService.BusinessObject = Me.bizSC_AppliancesItems1 I don't know why was this happening and it was very difficult to reproduce in the sample application, so since this worked, I just leave it and moved on to new issues.
