I have a database that has file attachments that have pdfs. When I click on this attachment in web app builder I get this:
Works fine in other browsers....anyone been able to fix this?
I have not seen this issue before. What does your browsers web console say? More than likely you need to call tech support and report this issue as it could be a bug.
Normally attachments are added in ArcMap. There is no otb widget for adding attachments. There are attachment editor samples for the JS API that would not take a developer to much effort to convert to a widget, but as of yet I have not seen one.
