Hey @natecavanaugh,

Attached is an update for http://issues.liferay.com/browse/LPS-45189.

NOTE: "Main thing I'm unsure about in this is the RowChecker changes, I needed to change that for the "list view" option of the Document Library" - @Preston-Crary 

Please let me know if you have any questions.  Thanks!
