Prevent and Catch Errors with Poka-yoke Devices: I could not find any examples poka-yoke devices within the web application.

Ditch Anything Modal: The application actually goes the other way and has several application-modal errors. If the user attempts to navigate away from the form without saving, it pops up a message saying, "

Confirm

Are you sure you want to navigate away from this page?

Press OK to continue, or CANCEL to stay on the current page."

The application also pops up an application-modal error if you try to save when there is a page break with no information on it.

Write Error Messages That Help Instead of Hurt: The error messages that do come up are written very clearly, and instruct the user how to solve the issue creating the error message. So, they are helpful error messages.

Create Forgiving Software: Unfortunately, this software is not very forgiving. If you do navigate away from the page without saving, your work is deleted and you would have to start from scratch.
