smart gwt comboBoxItem 不会根据用户输入进行过滤

Question

ComboBoxItem buildings = new ComboBoxItem("buildings", "Building Names") {
        public Criteria getPickListFilterCriteria() {
            Criteria criteria = new Criteria();
            criteria.setAttribute("dependentString", grid.getSelectedRecord().getAttribute("company"));
            criteria.setAttribute("dependentString2", "office");
            return criteria;
        }
    };
    buildings.setOptionDataSource(CommonLookupDS.getLookupDS(LookupTypesClient.LOOKUP_BUILDINGS_BY_TYPE));
    buildings.setValueField("key");
    buildings.setDisplayField("value");
    buildings.setWidth(125);
    buildings.setWrapTitle(true);
    buildings.setAutoFetchData(false);
    buildings.setRequired(true);

一旦覆盖了 getPickListFilterCriteria 方法，此组合框就会停止过滤用户输入。无论用户输入如何，它都会显示所有选项。如何解决这个问题？

Answer 1

我将所有条件设置都放入了数据源并且它有效。所以，在方法 transformRequest 中我做

public Object transformRequest(DSRequest dsRequest){
    dsRequest.setHttpMethod("POST");
    return "<json>";
}

Answer 2

这可以通过将条件附加到数据源来完成例如

buildings.setOptionDataSource(CommonLookupDS.getLookupDS(LookupTypesClient.LOOKUP_BUILDINGS_BY_TYPE
                                +"&dependentString="+grid.getSelectedRecord().getAttribute("company")+"&dependentString2="+office));

并防止覆盖 getPickListFilterCriteria 方法
