问题 I have an application that I want to print an invoice like document in a table setup. Each line in the table will be from a separate document from a database.

问题 I have a bunch of PDF's which I have merged by this point in the code. At the beginning of the merged PDF I have a contents page which links to said PDF's respectively. These pdfAction.gotoLocalPage links sometimes don't work correctly and instead jump to between the bottom of the page and the next, however the PDF bookmark hyperlinks always work fine.
