[s2] Making LazyDynaBean work with ModelDriven interface

[Mark Shifman <ma...@yale.edu>]

 Some folks may be as pig-headed as me or may need to use LazyDynaBeans 
as they are translating
from struts1 to struts2.  After fooling around, I figured it out but it 
is pretty clear to me this is not the way to go.
Below is a simple example.

public final class MyAction extends ActionSupport implements ModelDriven{

    private LazyDynaBean f = new LazyDynaBean();
    public String execute() throws Exception  {
       
        String[] text_field = (String[])f.get("text_field");
        //do something with the text_field that came from LazyDynaBean 
as a String array
               return SUCCESS;
    }
   
   public Object getModel(){
        return f;
    }
}

<s:form action="MyAction">
    <s:textfield name="map.text_field" />
    <s:submit />
</s:form>

<validators>
    <field name="map.text_field">
        <field-validator type="required">
            <message>Text Field is required.</message>
        </field-validator>
    </field>
</validators>

There were 2 things that bit me:
1.  You have to get the field name  from map.text field so that 
s:textfield can get it from the "map" on the valuestack and
2.  The textfield seems to get a String[] rather than a String and I 
don't have any idea how to do it differently.

I don¹t know if you can do this because I've never really worked with Struts
1. Can you make the Map in your form a Map<Object,String>? That might make
the values be String instead of String[]. This is only an idea.

I'm not sure OGNL will do this with generics. You could test it easily
enough by making your model just a Map<Object,String> and see if that works.
