xx is either a reserved keyword or is already assigned to another item.

I am currently working on a new project based on a previous one. It involves quite a lot of javascript and I am trying to copy an item from one document to the new one.

I keep getting the error message that my desired item name is already in use:

"[my object name] is either a reserved keyword or is already assigned to another item. Provide a different name for the item."

I know that there is no other item in my entire document with that name. Some trial and error showed that simply deleting and repasting an object would already cause the repasted item to be automatically renamed and won't allow the original name anymore.

Of course I could change the name, but that would mean a lot of work to change it everywhere in the code.

Is there any way to "reset" what captivate thinks is already in the project?
