I'm working on a document now in which I've had to assign new page headers to several pages. I made these changes, and printed the document to PDF. But the PDF didn't show any of my page header changes. It just reverted back to the old page headers.
Has anyone seen this? Is it a common glitch or something I can change myself?
How were these headers assigned?
The usual method is via Master Pages, which then need to be applied to the Body Pages, usually via the Apply Master Pages feature, controlled by the MasterPageMaps Reference Page content (which usually doesn't exist until you run the command for the first time).
You need header-unique Paragraph Formats to get the MP each BP requires.
Does it display correctly in your FrameMaker file?
