Hi there,
Thank you for your response,
Please see below observations:
If you add the following annotationChanged event handler:
const { annotationManager } = instance.Core;
annotationManager.addEventListener('annotationChanged', (annotations, action) => {
if (action === 'add') {
console.log('this is a change that added annotations');
} else if (action === 'modify') {
console.log('this change modified annotations');
} else if (action === 'delete') {
console.log('there were annotations deleted');
}
annotations.forEach((annot) => {
console.log('annotation page number', annot.PageNumber);
});
});
Then create a rectangle annotation then a free text annotation, calling exportAnnotationCommand will give you 2 annotations inside the ‘add’ element of the XFDF:
Afterwards, if I group the 2 annotations, then call exportAnnotationCommand, only one modified event is triggered and you will see that inside the XFDF, there is only one modified element, the freetext (second annotation):
This is why you are not seeing the parent annotation inside the XFDF. As you mentioned, this is the expected behaviour for annotation grouping.
We do not have a way to disable the annotation grouping, however you can simply block that button by hiding the element from the UI:
instance.UI.disableElement('annotationGroupButton')
Best regards,
