I am working on a project where i have to show download button for a blob file based on their file id.
I tried to find videos and docs for it and could not get much resources. I found this article on web : http://www.apexlessons.com/download-blob-file-from-database-in-oracle-apex/ .
I followed the steps mentioned in ut created application item and item process for it.
I also set a button in my environment with the link mentioned in the article, my application is breaking due to it.
I have attached screenshot
