I have been using the Embed API for over a year with great success. On the pdf manipulation side I was using iText 5 but needed to switch to iText 7 6 months ago to handle an issue with checkbox groups that span pages. Again, we have been working fine on 100s of PDF documents created by various Financial Institutions, different vendors, etc. but again successfully. Last week Thursday, it was reported that CheckBox groups ( radio buttons ) are not saving or being changed. I have spent 3 days and verified that I have not changed any code that would impact the saving of PDF data. So my question is .. did something change on your side?
This is pseudo code of the script in my HTML page using the Embed API: Pretty much right out of your documentation..
<div id="adobe-dc-view" style="width: 100%; height: 100%;" ></div>
<script src="https://documentcloud.adobe.com/view-sdk/main.js"></script>
<script type="text/javascript">
document.addEventListener("adobe_dc_view_sdk.ready", function() {
const saveOptions = { showSaveButton: true }
const previewConfig = { showDownloadPDF: false }
let adobeDCView = new AdobeDC.View({
clientId: "<my client id>",
divId: "adobe-dc-view"
});
adobeDCView.previewFile(
{
content: {
location: {
url: "@routes.FormWorkflowController.editWorkflowFormAsPdf( doc_id )"
}
},
metaData: {
fileName: 'doc.pdf'
}
},
{
embedMode: "FULL_WINDOW",
showPageControls: true,
dockPageControls: true,
showAnnotationTools: false,
showLeftHandPanel: true,
defaultViewMode: "FIT_PAGE",
showDownloadPDF: @hostserver.isLocalServer,
showPrintPDF: false,
enableFormFilling: true
}
);
adobeDCView.registerCallback(
AdobeDC.View.Enum.CallbackType.SAVE_API,
async function(metadata, content, options) {
let formData = new FormData();
formData.set(
"CaptureData",
new Blob([new Uint8Array(content.buffer, content.byteOffset, content.length)]),
"FormsLogic_PDF_Editor.pdf"
);
const response = await fetch("@routes.FormWorkflowController.uploadPDFForDataHarvest(doc_id)",
{ method: 'POST', body: formData });
if(response.ok) {
//move reload to end of js call stack (after promise is returned)
setTimeout(function() { window.location.reload(true); });
return new Promise((resolve, reject) => {
resolve({ code: AdobeDC.View.Enum.ApiResponseCode.SUCCESS, data: { metaData: metadata });
});
} else {
//adobe UI to display failed save without page refresh
return new Promise((resolve, reject) => {
reject({
code: AdobeDC.View.Enum.ApiResponseCode.FAIL });
});
}
},
saveOptions
);
});
</script>
The first PDF is a sample pdf that has been working for over a year that started not saving checkboxes last thursday.
Below is the pseudocode on my controller ...called by the registered callback above.
def uploadPdfForDataHarvest(...... ) = SecuredAction.async(streamingBodyParser(maxUploadSize)(newByteArrayOutputStream)) { implicit request =>
val keyword = "CaptureData"
request.body.file(keyword) match {
case Some(file) =>
file.ref match {
case Right(streamResult) =>
val bytes = streamResult.outputStream.asInstanceOf[ByteArrayOutputStream].toByteArray()
PdfGenerator.saveToFile( "public/output/adobe_returned_file.pdf", bytes ) <-- The second file above
val reader = new PdfReader( bytes ) <--- iText 5 or iText 7
val form = reader.getAcroFields()
val keys = form.getFields().keySet()
var data = Map[String, Seq[String]]()
data = data.++( keys.map { k =>
k -> Seq( form.getField( k ) )
} )
Note that I take the bytes coming in from the form data and write them out to a file which is the second file attached. Notice that the old radio button and the new radio button are both checked which seems like a bug to me since the field names for these should be the same and the values are what is different.
The form.getField( k ) call when it goes for the radio group always returns the first one ( 'Individual' ) even though that is old data and the new value '529 Plan' cannot be retrieved so that I can make the change.
Again, this was working last wednesday and now it seems to fail on all radio groups. I have not changed any code to impact this. The result is it seems...all getField(k) calls return the first value of the radio group ( selected or not ) when I get the result after a save.
