Hi Paulo, what means 'mixing other elements'?
I've added a small test program which mixes PdfPTables, Paragraphs and
Lists and the position returned by my getVerticalPosition has been
correct for all test cases. OK it will only work on document level but
that's absolutely OK for me.
By the way, can you explain the big amount between the second paragraph
and the first PdfPTable, shouldn't it be aligned to the rule like the
second PdfPTable does?
Best regards,
Christian
