I have setup a combobox to populate from a BO, just like I have set up a bunch of others, but on this one I am getting an error saying "The input value could not be converted to the output type".  I have checked the data types and have tried several different fields, but get the same error.  I'm just not sure what this error really means or where to look to solve this problem.  Please point me in the right direction.  Thanks!

It gives me the following stack trace...
