Please give a brief summary of your issue:
Notes Panel Shows Incorrect Annotation Count When Importing XFDF in Chunks Using importAnnotationCommand
Please describe your issue and provide steps to reproduce it:
When loading annotations from the database in chunks and importing XFDF using annotationManager.importAnnotationCommand, the Notes panel displays a higher annotation count than the number of annotations actually rendered on the document.
Example:
-
API returns 50 annotations
-
Only 50 annotations are visually rendered
-
Notes panel shows 75 / 200+ comments
Expected Behavior
-
Notes panel count should match the number of unique annotations imported and rendered.
-
Importing 50 annotations should result in 50 notes.
Actual Behavior
-
Notes panel count increases unexpectedly.
-
The count jumps by tens or hundreds, even though only a few annotations are visible on the page.
-
This happens specifically during chunked XFDF imports.
Key Findings (Important)
After investigation, we found:
-
importAnnotationCommand()does not guarantee a 1:1 mapping between:-
One XFDF input
-
One annotation object created
-
-
Some XFDF commands appear to:
-
Replay
<add>or<modify>operations -
Re-apply changes to existing annotations
-
Create additional internal annotation objects
-
-
As a result:
-
The document visually shows the correct annotations
-
The Notes panel counts all internal annotation objects, including duplicates or overwritten ones
-
-
Concatenating multiple XFDF strings into a single call significantly amplifies the issue and causes massive inflation in Notes panel count.
What Does NOT Work
-
Concatenating multiple XFDF strings into one
importAnnotationCommand -
Skipping
importAnnotationCommandand trying to manipulate XFDF directly -
Applying styles without importing annotations into
annotationManager
importAndStyleChunk: async function (annotations) {
const self = this;
self.showAnnotationLoader();
const annotationManager = window.webViewerInstance.Core.annotationManager;
for (const a of annotations) {
const importedAnnots = await annotationManager.importAnnotationCommand(a.annotData);
importedAnnots.forEach(annot => {
annot.setContents(a.text);
self.applySecuritySettings(annot);
annotationManager.redrawAnnotation(annot);
});
await new Promise(resolve => requestAnimationFrame(resolve));
}
},
