--------------------------------------------------

+ '''''Thiago H. de Paula Figueiredo: this approach is plain wrong. You have to 
retrieve a list of objects when you need just one of them (wrong) or put a list 
in a session (very wrong). In addition, the same class implementing two 
completely different interfaces is not a good idea. Just create one instance of 
OptionModelImpl for each of your options (objects) and pass them to a 
SelectModelImpl.'''''

  Creating a <SELECT> is a bit complicated and there is only support for 
strings and enums currently. (T5.0.13)
