How does you export the file?
Unless you export the pages by printing them to the Adobe PDF printer all the actions on the objects they contain should remain exactly the same. So how are you doing it currently, exactly?
I misspoke on the export... we are doing an extraction to get certain pages separated from the larger overall document.
Is it possible to do this through extraction?
What kind of "extraction"? How are you doing it, exactly?
You will get this message when you combine files with same form fields.
This has nothing to do with extract or export pages.
We have asked (more than once) exactly how you extract. Please answer this - not the effect, but what you click and choose for options. Screen shots may help. You need to answer this, because it seems crucial to the problem.
