webgl一个工作空间中的多个数据源点选查询

SuperMap webgl不能实现多多个数据源的多个数据集进行查询(http://qa.supermap.com/47618),通过验证,也不能实现对一个工作空间中的多个数据源进行点选查询

        viewer.pickEvent.addEventListener(function(feature){
            var title = Cesium.defaultValue(feature.NAME,'');
            var description = Cesium.defaultValue(feature.DES,'');
            title.innerText = title;
            des.innerText = description;
            myimg.src = "./images/" + title + ".jpg";
        });

    }
</script>

请问:有什么办法能解决这两个问题(或者其中的任意一个)???

如果您是一个缓存的话,现在支持对一个数据源下的多个数据集进行查询,不可以对多个数据源查询的。

一般来说一个缓存内的数据都会在一个数据源下的
