Matt, Thanks for the response. Are you saying that the getter and setter methods will be called with an index value? So the setter signature in my example would be: void setVerified(int index, String value) and the setter would be void getVerified(int index) ?
Also, how do I know the list size to deal with and therefore know how to size the string array? Thanks, I appreciate your help.
