I've scoured the web and these forums looking for someone else with a similar problem in hopes of finding a solution to this.
I'm using the latest versions of InDesign CC and Acrobat Pro DC on macOS 10.14.4.
I have two InDesign documents—DocumentA.indd (a booklet, one of hundreds like it) and DocumentB.indd (a couple of reused pages common to all booklets). Each document contains an interactive button linking to a destination URL with a simple rollover state change (background color).
I can export each of these documents to an interactive PDF and everything looks and functions as expected.
The problem arises when I import DocumentB into DocumentA and export that as one final PDF for distribution. The interactive buttons that are in DocumentA work fine as before, but the buttons in DocumentB no longer work—no rollover appearance change and no link functionality.
Alternatively, setting them up as hyperlinks instead of buttons yields the same results. The hyperlinks in the imported file do not make it through to the exported PDF. It appears the import process strips out the interactive content, or at least InDesign doesn't see that particular content to export it correctly.
Yes, I know I can export each document as a separate PDF and then combine them in Acrobat—I've tested that and it works, with all interaction preserved—but for the quantity of projects involved here it's just not feasible. Ultimately I need to be able to create an InDesign template for all future iterations of DocumentA, all containing those same few DocumentB pages.
Is this a bug, or do I need to change some setting somewhere to allow/enable interactive buttons in imported InDesign documents?
