PDV Viewer: mI is not a function

[Danielle]

When adding a PDFViewer component, I get this error:

jQuery.Deferred exception: mI is not a function TypeError: mI is not a function

This occurs whether I use a valid PDF file on initial load, or if I use the menu to open and test an existing document.
