It is funny, but, when I have this line:

Imports iTextSharp.text.pdf

The designer would indicate a "Type expected" on one of the top declaration:

        Public oField As Collection = New Collection

It seems we cannot use collections when we have an import to iTextSharp.text.pdf. Can you try to add a declaration like that on top of your class to see if you will get the same?
