Invalid operation - create not allowed

rbellow posted on Tuesday, October 16, 2007

I am simply trying to create a new object.

Example:

MyBusinessObjects.Library.Employee.NewEmployee()

It errors with the message 'Invalid operation - create not allowed'

The trace suggests it fails in DataPortal_Create()

Any ideas on how I can get more detail as to why this is failing? I tried to comment out the ValidationRules.CheckRules() with no success.

<RunLocal()> _

Protected Overloads Sub DataPortal_Create(ByVal criteria As Object)

'ValidationRules.CheckRules()

End Sub

Make sure you're calling the DataPortal.Create with your criteria object - if you're calling it without a criteria object (that your overload is expecting) I suspect the DataPortal may be calling the Csla.Core.BusinessBase's DataPortal_Create directly (not your overload).

Bottom line is that the execution is running through the BusinessBase's DataPortal_Create, and that's why it's throwing the exception.

That's exactly it. I used CodeSmith to generate the object and just assumed that the _Create would not expect a criteria object. Thanks.

Do you need to pass criteria?  If not, you want overrides, not overloads.

Don't need it. So i will use overrides. Thanks again.
