extjs4对于store返回多条数据，但表格中只显示一条数据的问题

我碰到的情况是返回的 字段id为“0”的缘故， extjs会把id为0的所有数据当做是一条数据， 返回为null，则没问题。返回数据格式如下：

[{"id":”0”,"createTime":null,"updateTime":null,"marker":null,"baz001":0,"aab301":"000000","bab005":null,"bab006":"-未选择-","bab007":0,"baz031":0,"baz003":null,"dictitemId":null},
{"id":”0”,"createTime":null,"updateTime":null,"marker":null,"baz001":16,"aab301":"null","bab005":"null","bab006":"xxxx","bab007":3,"baz031":0,"baz003":null,"dictitemId":"72"}]
