Error during deleting BO record in a Form

Luiz Lima — Mon, 08 Mar 2010 09:20:34 GMT

Hi,

I have a form with a ParentBO and 3 children (I´m using DevExpress grid with BBS).
When I try to delete the record by Form, appears this message below.

I´ve been looking for some configurations on my BOParent or Form and .. Nothing....:crying:
This occurs when BoChildren are filled or not.

Some help guys?

2. Build the StrataFrame source code in debug mode so that we can at least see a line number which might clue us in. A NullReferenceException is a totally ambiguous exception to work off of here.
R: How can I do that?

Luiz,

Install the source code using the EXE provided in the Downloads. Open the StrataFrame source code solution, place it in Debug mode, and then build it. There is a .bat file that will register the DLLs in the GAC.

To place it in Debug mode, have a look at your VS Build menu, and see if you can find the "Configuration Manager..." option. If not, go to Tools, Options, Projects and Solutions, General and check the "Show advanced build configurations". Then, have a look at it and you will find the Debug/Release configuration option.

1. Does this happen when you are not bound to a grid?
R: Primary BO is bound to form and others three BOs are bound to grids.

2. Build the StrataFrame source code in debug mode so that we can at least see a line number which might clue us in. A NullReferenceException is a totally ambiguous exception to work off of here.
R: How can I do that?

Or

3. Create a sample that reproduces the problem and post it so we can look at this ourselves.
R: I´m working in another form to see if this problem occurs.

Tks

Well, there is not enough information for me to work with here. It almost seems like something is being re-evaluated in the grid, but I cannot tell for sure.
