Subject Re: Loop Component

Many thanks for your reply Sven.

However, I think that I didn't explain the problem properly.

If my, much simplified, java class is like this :-
<pre>

public class comp {

    //note getters/setters/annotations not shown

    private B valueItem;

    private List<B> items = new ArrayList<B>();

    public List<B> getSourceList(){
          B item1 = new B();
          item1.setEmail("peter@courcoux.biz");
          item1.setName("Peter");
          List<B> sourceList = new ArrayList<B>();
          sourceList.add(item1);
          return sourceList;
    }
}

and a comp.tml including :-

                <tr t:type="loop" source="sourceList" value="valueItem">
                    <td>
                        <t:checkbox t:id="..." value="selected"/>
                    </td>
                </tr>

and use a setSelected(...) method  (not shown) to copy a ticked
valueItem to the items list,
then

    in the case of (1)

public class B {
    private String name;
    private String email;
    ...
}

All is fine.


However, if we have the case of (2)


public class A {
    private String name;
    ...
}

public class B extends A {
    private String email;
    ...
}
</pre>

then the objects in the items list have email correctly set and name ==
null, where both should have been set.

I am using t5.0.13 and java6.

Any pointers/thoughts much appreciated.

Regards,

Peter
