Please refer to the attachment.

For the field name or Include Field Indicator Check, the event works normally.

However, for Read Only Check Box, Required Check Box, and File Size Input, the annotation Changed Event does not work even if the modifications occur, is there a solution?

annotationManager.addEventListener(
          "annotationChanged",
          annotationChanged
        );


const annotationChanged = async (
    annotations: Core.Annotations.Annotation[],
    action: "add" | "modify" | "delete"
  ) => {
    if (!instance || isImportingRef.current) return;

    console.log({ annotations, action });
}

Hello, I’m AiRon, an automated tech support bot
While you wait for one of our customer support representatives, I can help you with your question.

It seems you’re experiencing issues with the annotationChanged event not triggering for certain modifications within a Signature Form Field in WebViewer. This event should fire whenever an annotation is added, modified, or deleted, but there are scenarios where it might not be working as expected for specific field modifications.

Some things you can try:

• Check if the annotationChanged event is properly set up and listening for changes on these specific form fields.


• Ensure that the fields in question (Read Only, Required, and File Size Input) are correctly linked to the event listener.


• Verify that the event handler is not filtering out these specific types of changes by mistake.


• Consider using the imported or isUndoRedo properties of the event’s info object to handle specific cases differently.


• Test with other types of annotations to confirm if the issue is isolated to Signature Form Fields.

Hi Rlaks5757,

Thank you for reaching out.

I can confirm we don’t have an eventListener for this type of changes for now.

You can make a feature request to create an eventListener on these changes here:
