An additional bit of sample code would make everything complete. Merely looking at the samples you gave I can only say that the way the multi-page signatures is not 100% clean --- you have a P value pointing to the first page dictionary in the one annotation/field dictionary which actually is attached as annotation to the page dictionaries of both pages. Thus, in case of the second page, the P value is wrong. Acrobat and Reader don't seem to care, though. In my eyes it would be best not to have field and annotation dictionary merged. Instead having one field dictionary with one individual widget annotation dictionary for each page would be a cleaner approach.
