Update all signature fields in a PDF Document

[Marius Leustean]

Description:

A multi-page PDF document has a signature field on each page.

The PDF Viewer is opened with `enableFormDesigner = false` because I do not want that the user to be able to add, edit or delete the existing form fields.

Requirement:

When the user fills a signature field (on a random page), I want to update all the other signature fields within the document (regardless on the page in which they exist) - with the same signature filled by the user.

The code I've tried:

- in a callback for the `addSignature` event, I store the `event.data` in a variable.

- I get all the fields in the document with the `retrieveFormFields()` method and filter those that are unsigned.

- for each field described above, I use `updateFormFieldsValue(field)`. A sample of the code would be:

formFields.forEach(field => {
  field.signatureType = [signatureType]; // Draw, Type or Image
  field.value = data;
  if (signatureType === SignatureType.Type) {
   field.fontFamily = signedField.fontFamily;
  }
  this.pdfViewer.updateFormFieldsValue(field);
​});

​The issue:

It doesn't work. Even if the field values are updated, the signature is not drawn in the field.

Can you please help me with a solution?

Thank you!
