Missing parts of attributes when identify with admin privilege

[zju-niran]

When identify the features of the layers http://128.31.22.46/maps/new?layer=geonode:zhejiangcuangtongmudao00 in test server stage, we can see all the attributes, such as link, link2 and descripto as the below picture.

But in amap server, we can only see parts of fields excluding link, link2 and descripto.

When open the debug mode of geoexplorer-worldmap-client, we find 'layer.attribute' is [] but not null of most layers in amap.
