Right, here's the deal this time.

I have an edit page using objectdatasource, as demonstrated in the adef tutorial (Creating a DotNetNuke Module 4). I get everything showing up in my gridview on the edit page, I can get to the edit mode of the datagrid and all data shows up. But when I try to "update" my update function in the controller class throws an exception (A critical error has occurred. Exception has been thrown by the target of an invocation.). I found that it actually was my controller class update function that caused this when I ran the site in debug mode.

The update method for the datasource is "updatePersonal"

the function in the controller class is the following: 

<DataObjectMethod(DataObjectMethodType.Update)> _
		Public Shared Sub updatePersonal(ByVal objInfo As whiteboard_personalInfo)
			DataProvider.Instance().updatepersonal(objInfo.namn, objInfo.id, objInfo.foto, objInfo.huvudansvar, objInfo.telefon, objInfo.mail, objInfo.rumsnummer, objInfo.backupperson_id)
		End Sub

 where the whiteboard_personalinfo is my info class.

any ideas of why this doesn't work? It seems to be a problem with the "Dataprovider...." line, since it doesn't thrown an exception if I comment it. All the values inserted are of the right data type, my dataprovider.vb file is equivalent to what it looks like in the tutorial. There has to be something I'm missing here...
All includes are checked to be as they are in the tutorial. It's either a big error or something so small that I can't see it

Both the dataprovider and the sqldataprovider seems to be ok. They have the same order and the same data types as the ones I pass on from the info class. Can there be some kind of error when grabbing the data from the info class?


I'd be thankful for any help on this issue.
