Form Fields are not loading??

[m0ntymccune]

Is there something I must do in order to display filled forms?

could you please provide an example?

It’s perhaps a strange case, but what I’m doing is loading a pdf form, populating it via script, and the trying to display the results… PDFLib.PDFDocument.load(formPdfBytes).then(pdfDoc => { // Get the form containing all the fields const form = pdfDoc.getForm(); //get pdf_instance fields and set values... for(var i = 0; i < self.od_pdf_instance.OD_PDF_Instance_Values.length; i++){ var instanceValue = self.od_pdf_instance.OD_PDF_Instance_Values[i]; var field = form.getTextField(instanceValue.FieldName); field.setText(instanceValue.FieldValue); } pdfDoc.save({updateFieldAppearances:false}).then(pdfBytes=>{ var b = pdfBytes; const pdfBlob = new Blob([pdfBytes], { type: 'application/pdf' }); const pdfURL = URL.createObjectURL(pdfBlob); //THIS DOESN”T LOAD THE POPULATED FORM FIELDS... let pdfViewer = new PDFjsViewer($('.pdfjs-viewer'), options); pdfViewer.loadDocument(pdfURL); //IF I USE CHROME’s PDF VIEWER HERE, IT WORKS PERFECTLY... // var iFrame =document.getElementById('pdfiframe'); // iFrame.setAttribute("src", pdfURL); If I use Chrome’s PDF viewer with the pdfURL, it works perfectly, but when passing the same URL to pdfViwer.loadDocument, it doesn’t load the form fields :(
