Upgrading an APEX 5 application to APEX 20, we have a file load page that uses a File Browse item with the File Types set to: text/csv.
This is working fine in production, but when I run this in our APEX 20 version we always get the message that the file is not text/csv.
It does work if I set the File Types to: .csv.
As far as I can see, the HTML generated in production and dev is the same - the File Types is used to populate the 'accept' attribute of the file input item.
What's going on?
