Hello Dale,

I believe this is actually the expected behavior because when you drag an annotation to a new page, it creates a new one. This triggers the ‘add’ event as well. The old one will have to be removed which triggers the ‘delete’ event.

Thanks Darian.

I was currently using an object as a proporty on the stamp, as I syncronize state between the annotationlist and array of provided annotations.

Is the best way to do this using get/set CustomData?

Hello Dale,

If your goal is to keep track of the annotations that move across pages, I think get/setCustomData should work fine.

Perfect. This works.

Just had to update the annotations ID to the original id, which we store in the custom data
