Hi

I'm upgrading from 6.1.6 and it works fine until the database is 100% updated then the error occur.
I have updated bin, ,umbraco, umbraco_client and merged config. I have deleted app_data\temp

I have done it several times now on a machine where I have installed a new 7.0.1 version without problems.

I have downloaded the source and found out that it occurs when this is performed:

SELECT *
FROM [umbracoUser]
LEFT JOIN [umbracoUser2app]
ON [umbracoUser].[id] = [umbracoUser2app].[user]
WHERE (umbracoUser.id = @0)

in petapoco.cs here

try
{
   if (!r.Read())
     break;
 poco = factory(r, cb); // calling on from here
}
catch (Exception x)
{
 OnException(x);
    throw;
}

to this

public TRet CallCallback<TRet>(Delegate callback, IDataReader dr, int count)
{
    var args = new List<object>();
   for(var i = 0;i<count;i++)
  {
      args.Add(CallDelegate(i, dr)); / and from here
 }
 return (TRet)callback.DynamicInvoke(args.ToArray());
}  

private object CallDelegate(int index, IDataReader reader)
{
    var d = GetItem(index);
    var output = d.DynamicInvoke(reader); // which calls
  return output;
}

this

Convert.ChangeType(src, dstType, null)

where src is an object og value 1 and dstType is an datatype Int16.

Exceuting the inital query gives me this
id userDisabled userNoConsole userType startStructureID startMediaID userName userLanguage user app
