Interactivity (buttons setting layer visibility) is not preserved when replacing page in Acrobat

I made an interactive pdf by creating buttons to set layer visibility on and off on hovering. Now I want to replace the 'base/background' pdf (because my client wanted to change 2 words...) while preserving the interactive buttons. This should work (Organize pages --> Replace with new 'base' pdf file) but it doesn't: buttons remain but the actions aren't working anymore.

The original file is made in Illustrator --> save as PDF --> Create acrobat layers from top-level layers. Names of the layers are exactly the same; only the base layer changed.

Please help?

I guess this is because you're using the "Show/Hide layer" action.

You should use a JavaScript instead.

Please tell me how I do that...?
(I don't know JavaScript) (and it should work in Acrobat - for those of us who don't know JavaScript...)

To show a specific layer ("MyLayer1", in this example) you can use this code:

var ocgArray = this.getOCGs();
if (ocgArray!=null) {
	for (var i=0; i<ocgArray.length; i++)  {
		if (ocgArray[i].name=="MyLayer1") {
			ocgArray[i].state=true;
			break;
		}
	}
}

To hide it replace true with false in line #5. If you need to do this multiple times it's of course possible to place this code in a generic doc-level function where you specify the layer name and new state (hidden / visible) as input parameters and just call it each time.

Are you sure the layers are still there after you replace the pages? Do you see them in the Layers panel?

Definitely: the layers are there; the buttons are there (with the same action settings); the button just doesn't work... (when hovering, the 'hand' appears but no other layer is shown)
