Child DTOs null

Hi,

 

I am using GWT with Hibernate..

And i use Dozer for mapping between Hibernate & DTO objects.

I could retrieve the data ...

On server side i could get the child objects(many to one relationships)data too..

The RPC call returns a parent object.

I could also populate this parent DTO object data.

But when i try to populate these child DTO objects,it returns null..

-My code is

 

void setData(ParentDTO parent)

//parent is the result returned by RPC method

{

txtbox1.setText(parent.getID());

txtbox2.setText(parent.getName());

 

 

txtbox3.setText(parent.getChild1().getName());   //---------Null pointer Exception

 

}

 

 

I could get the output for the 1st 2 textboxes...

 

While trying for 3rd textbox i get the nullpointerexception.....

 

Can anyone tell me what should i do to get the child object data on the clientside???

 

Thanks,

Nalini.T
