I do think this could fall under WCAG2.0 3.3.4, quite possibly (G168). I believe that if the visual user can see it on the screen the screen reader needs to read that as well. Many, many web pages do give an error when requesting to leave the page.

Perhaps adding a window.onunload event handler that brings up a confirmation dialog may be of use? Keep track of whether or not a user has entered any new data, and if so on unload bring up something like

confirm("If you leave this page without saving, your changes will be lost.");

In addition, if that happens, any information entered must be retained, should the user come back to the details page, regardless of how many links navigated away from the page.

The help file for the application does mention information must be saved before navigating away from the details page. I also believe the user is making a conscious decision to navigate away from the page and retaining the information entered is not required.
