I've got a normal HTML 5 form for uploading. When I click on add files, I get prompted with all sorts of apps I can upload from. Let's say I choose dropbox. When I pick a file to upload from DropBox, the browser fails to open the selected file returned from DropBox.
A colleague says this is because we have the database ID from the file. I'm wondering if there's a way to detect that this is what was returned and do something about it better than just failing... Like maybe worse case, tell the user why it failed (we'd have to be able to detect that it failed). Or better, somehow detect that it was a database ID of the file and be able to go get it from our web page.
