i had this exception when my webservice was tring to execute the code below...

Dim t As namespace.editableroot
t = namespace.editableroot.Neweditableroot()

the editableroot class was created using the csla2.0.x version... and now im changing it to csla3.0.2...

this is the whole message - DataPortal.Create failed (System.NotSupportedException: Invalid operation - create not allowed
   at Csla.Core.BusinessBase.DataPortal_Create() in C:\development\Csla\ver_3_0_2\cslavb\Csla\Core\BusinessBase.vb:line 1184)

dont know why this is happening...

This exception is thrown by the CSLA core BusinessBase class if you don't override the DataPortal_Create() method.

If you are using the Data Portal to create a new instance by calling DataPortal.Create() then you MUST override this method in your class.

Assuming you are overriding the Dataportal_create method in your object verify your calling statement and the method both include or exclude a criteria argument. 

eg

Public Shared Function NewMyObject() As MyObject

If Not CanAddObject() Then

Throw New System.Security.SecurityException( _

"User not authorized to add a Object")

End If

Return DataPortal.Create(Of MyObject)()

end function

Private Overloads Sub DataPortal_Create()

...

Select defaults from wherever

end sub
