Do something like this:
public void appendToResponse ( WOResponse aResponse, WOContext aContext
)
{
personBatch.queryBindings().takeValueForKey ( myBinding,
"myAttribute" );
personBatch.qualifyDataSource ();
super.appendToResponse ( aResponse, aContext );
}
The WODisplayGroup should have a FetchSpec correctly set.
