Hi everybody,
i'm trying to use the class PdfCopyFields for copying PDFs with fields.
There are the same fields on different pages of a PDF and the fields
have attached javascript (a coloured border is shown, when the focus
is in the field). Therefore i'm using kid-fields with method setPlaceInPage().
When copying the PDF with PdfCopyFields the fields are copied correctly, but
the javascript ist lost. In fact, the javascript is attached to the field,
but not to the field-kids any more.
Does anybody have an idea?
Thanks,
Peter
