how to update a field value?

[chaohua wang]

Hi, Folks,

in the orderstatus.bsh file.

oii = orderItems.iterator();

    while (oii.hasNext()) {
        oitem = oii.next();

        String itDes = oitem.getString("itemDescription");
...........................
}

I want to update itemDescription value.  I tried to use

 oitem.updateString("itemDescription", "®");

but threw the exceptions:

Method updateString( java.lang.String, java.lang.String ) not found in
class'org.ofbiz.entity.GenericValue'))

Could you tell me how to update itemDescription of orderitem?

Thanks
