示例1: generateData
import com.vaadin.v7.data.Item; //导入依赖的package包/类
@Override
public void generateData(Object itemId, Item item, JsonObject jsonRow) {
JsonObject jsonData = jsonRow.getObject("d");
for (String key : jsonData.keys()) {
if (getColumn(key).getRenderer() == this) {
// 2: VERY IMPORTANT get the component from the connector tracker !!!
// if you use a GeneratedPropertyContainer and call get Value you will
// get a different component
if (jsonData.get(key) != Json.createNull()) {
Component current = lookupComponent(jsonData, key);
trackComponent(itemId, current);
}
}
