Doc.Objects Qustion with Blocks

Hi all,

When I for example have 3 objects named A,B and C. Put them in a block and get doc.Objects. None are found because they are in doc.InstanceDefinitions - getobjects.

But when I EditBlock Rename object A with D, A is still found when I loop doc.Objects until I leave EditBlock. Why? Because A doesn’t exist anymore.

Example Code (all items found are in the list called Names):

Dim Names As New List(Of String)
Dim Obj = doc.Objects
For Each o In Obj
    If o.ObjectType <> DocObjects.ObjectType.InstanceDefinition And o.ObjectType <> DocObjects.ObjectType.InstanceReference Then
        If Names.Contains(o.Attributes.Name) = False And o.Attributes.Name <> "" Then
            Names.Add(o.Attributes.Name)
        End If
    End If
Next

For Each Block As Rhino.DocObjects.InstanceDefinition In doc.InstanceDefinitions
    For Each o As DocObjects.RhinoObject In Block.GetObjects
        If o.ObjectType <> DocObjects.ObjectType.InstanceDefinition And o.ObjectType <> DocObjects.ObjectType.InstanceReference Then
            If Names.Contains(o.Attributes.Name) = False And o.Attributes.Name <> "" Then
                Names.Add(o.Attributes.Name)
            End If
        End If
    Next
Next

What you describe is what I expect. Is there a question here?

My question is why A still exists when I renamed it to D, because A doesnt exist in my drawing anymore.
