Hi,
i just started using csla.net after reading the book the first time (i think i am going to read it once more...)
But anyway, i followed the book setting up a web page to insert customer data into a database.
My process is related to setting up the projects in the ProjectEdit.aspx.
When the page is loaded i see my list of customers, which is fine (and means that the access to database works...) As soon a i press my new customer button, i get an exception "Dataportal.Create failed."
If i look closer into the exception there is another line : Invalid operation - create not allowed.
Also it says that the error is in BusinessBase line 906 when DataPortal_Create is called.
Here is the complete error message:
Line 904: <System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Naming", "CA1707:IdentifiersShouldNotContainUnderscores", MessageId:="Member")> _
Line 905: Protected Overridable Sub DataPortal_Create(ByVal criteria As Object)
Line 906: Throw New NotSupportedException( _
Line 907: My.Resources.CreateNotSupportedException)
Line 908: End Sub
