I had a binding to the text of a button which didn't had a corresponding resource. Once I added the string resource it worked.&nbsp;</p><p>As a sugestion I'd say: add more meaningful error messages. Thanks</p>http://www.intersoftsolutions.com/Community/Crosslight/Error-on-RegisterViewIdentifier/Tue, 25 Nov 2014 13:20:32 GMTpedro1412<p>I'm adding a new view on my view controller by overriding the method InitializeViews. Right after I add my view &nbsp;to the view controller I register it using RegisterViewIdentifier. After this I get a NullReferenceException on ViewDidLoad, but I don't even have anything there. If I remove the calls to RegisterViewIdentifier I get no error, but the bindings obviously don't work.</p>
