I want to nest list of answers in Data Table which already have data provider
.Below code gives error
IColumn[] columns= { new PropertyColumn(new Model("ID"),"questiontext"),
new AbstractColumn(new Model("Answer Body"))
{
public void populateItem(Item cell,String componentId,IModel
rowmodel)
{
MCSSQuestion q=(MCSSQuestion)rowmodel.getObject();
List a=q.getMcssans();
ListView view=new ListView("lists",a)
{
protected void populateItem(ListItem item)
{
final MCSSAns ans=(MCSSAns)item.getModelObject();
item.setModel(new CompoundPropertyModel(ans));
item.add(new Label("ansbody"));
}
};
cell.add(view);
}
