What I'm trying to do is create a hyperlink on an Opportunity form.
AFAIK, there're two appropriate ways to format such data:
1. Using text type
2. Using URL type
The problem is when you paste a link to local resource, like \\filestore\folder1, the URL formatter prepends it with http://, creating a hyperlink http://\\filestore\folder1 (which doesn't work) instead of file://\\filestore\folder1 (which works correctly).
Previous solution like creating a text field storing link text (\\filestore\folder1), and a button on a form. Using button onclick event and passing text field value as URL parameter by manipulating the DOM stopped working after on premise rollup 1.
Any suggestions how to do it now?
