OrderItem PDF download

[jollopre]

When trying to download a PDF for a given order item through Firefox, the PDF appears to be generated by the server, however in Firefox the dialog to download/cancel the file attachment is not prompted.
The time estimated to complete this task is 3 hours.

The exporting functionality for orderItem returns binary data to the browser. As that URL resource is protected, i.e. requires http authentication with token, the client code (e.g. JavaScript) generates an HTML anchor whose URL represents a blob object from the data received.

Chrome and Sarafi behave fine if JavaScripts triggers the click for an HTML anchor, however Firefox requires any HTML anchor to be appended to a document in order to work properly. See more details regarding Firefox unexpected behaviour at (https://bugzilla.mozilla.org/show_bug.cgi?id=1218456)
