createAnnotation() forces first annotationPage id

[martimpassos]

It seems to be using a hardcoded value instead of the id argument, is this expected behavior?

That was a convenience feature, so you can add Annotation instances directly without having to worry about the AnnotationPage. If there is already an AnnotationPage, it will use that instead, or you can add an AnnotationPage with Annotations manually.

I think you could also go back and change the ID on the annotation page. We could allow you to pass in ID to the createAnnotation() options though.

Correct me if I'm wrong, but the function seems to already have that option, only unused.

How would you go about renaming the annotation page? Accessing the object like manifest.canvas.annotationPage.id = 'new/id'?

[stephenwf]

You could instead add the page manually:

canvas.createAnnotationPage(`https://example.org/custom-id`, (annotationPage) => {
  annotationPage.createAnnotation(annotation);
});
