Hello,

I have asked why JavaScript was not showing a layer that I know exists here:

https://community.adobe.com/t5/acrobat-sdk-discussions/how-to-show-hide-single-layers-in-browser-with-javascript/m-p/15103693#M93768

Working with Thom Parker it was determined that the failure to show a layer was due to multiple layers. In that thread, I discuss a work around that prevents Illustrator from creating multiple layers such that only single layer instances are saved and thus JavaScript shows and hides layers.

Previously, when adding a PDF as a graphic element to FrameMaker or InDesign I would get a "Layers don't match" error. This had no effect and so I never looked into it, until now when it prevents JavaScript from working as indicated here:

Feel free to contact me. Fermilab has subscribed to Creative Suite, so I am using the last released version of Illustrator.

Illustrator should not be generating multiple layers.
