mapping with automapper missing properties

I'm facing a issue with mapping my objects to the view and back to the original object with automapper.

I have following structure.

public class TModel
{
  public int TID{get;set;}
  public string Name{get;set;}
  public string Location{get;set;} 
  public string address{get;set;} 
}
public class UiModel
{
  public string Name{get;set;}
  public string Location{get;set;} 
}

in the class AutoMapperConfiguration i have a initialize of my automapper like following: 

cfg.CreateMap < TModel, UiModel  >();
cfg.CreateMap < UiModel,TModel > ();

my adapter recieves data from a webservice, this data i wil store in a list of TModel items The view only show items of UiModel, i will do the following mapping en return the data to the view

var list = listOfT.Select(tmodel=> Mapper.Map<UiModel>(tmodel)).ToList();

when all of the changes are made i give the list back to a different adapter to save the data into the database

in this 'sqlAdapter' i map the items back of type TModel, because i also want the address property in my database

var list = listOfUi.Select(uimodel=> Mapper.Map<TModel>(uimodel)).ToList();

but now i have lost the data of the address property. must i also pass throug the original list of TModel's?...

There's a couple different ways you could solve this. The simplest answer would be to modify your UiModel class so that it has an address property. So something like:

  public class UiModel
    {
      public string Name{get;set;}
      public string Location{get;set;} 
      public string address {get;set;}
    }

Automapper works by first trying to match property names. If it doesn't find a match then you have to either modify your class so that it finds a match or write a class that implements the IValueResolver interface. More on that can be found at https://github.com/AutoMapper/AutoMapper/wiki/Custom-value-resolvers
