Issue with Checkbox ListView on Page Load

Right when the page is loaded I get the error attached on this post. It's supposed to show a list of documents the user can select. The ListView still shows up, but it's not populated and the session disconnects. I've tried removing different parts of the ListView code shown below to see if that would help, but no matter what I remove it still seems to happen. The error attached is an ArgumentOutOfRange Exception. There are about 60 available documents if that matters. ID is a GUID, DocumentTypeName is a string, and IsChecked is a bool.

Okay so I've narrowed it down a bit. It's due to the list of objects that I'm getting the Argument Out Of Range exception. I've made a list of strings with the document names and nothing else, and the list populates without error; however, whenever I introduce a list of POCOs (the poco has about 15 properties, including a Guid, a string for a name, and a bool for the IsChecked property of the list view) the whole thing fails and the list does not populate. None of my POCO properties are read-only, but it's something to do with using a list of POCOs vs a list of strings. Thanks again!
