there's a grid in a goods-order page,in which the custormers could type goodsname in it to form a order.
I've bind all other data to datamanager.and also, I want to bind the goods data to datamanager.I did like this:

------------------------------------------------
<grid model="@{goodslist}" id="goodsgrid">
<columns>

<column label="goods name" />
<column label="color" />
<column label="num" />

</columns>
<rows id="rows">
<row self="@{each='goods'}">
<combobox autodrop="true" value="@{goods.name }" />
<combobox value="@{goods.color }" />
<intbox />
</row>
</rows>
</grid>

--------------------------------------------
but there's a problem: when page load, the goodslist is empty, and no rows is displayed to the user.
I tryed to add a blank row like this which will work if I didn't band it to datamanager:

-----------------------------------------
void addnew(){
Row nrow=new Row();

nrow.setParent(rows);
new Label("new row").setParent(nrow);
new Textbox().setParent(nrow);


}

-------------------
but it pops error: "index 0,size 0"

and then, I tryed to add a blank row like this:

------------------------
void add(){
TreeSet gl=new TreeSet();
shen.Goods goods = new shen.Goods();
goods.setName("NAME");
goods.setCname("color");
gl.add(goods);

bill.setGoodslist(gl);
}
---------------------------
the new row didn't appear too.

Could anyone please tell me the way to add rows to a livedata grid ?
