我通过json数据初始化，选中数据只设置子节点，发现父节点未半选或者选中，这个是BUG吧？
var setting = {
data: {
simpleData: {
enable: true
}
},
check: {
enable: true,
chkStyle: "checkbox",
chkboxType: { "Y": "ps", "N": "ps" }
}
};
var treeNodes = [
{"id":1, "pId":0, "name":"test1"},
{"id":11, "pId":1, "name":"test11"},
{"id":12, "pId":1, "name":"test12"},
{"id":111, "pId":11, "name":"test111", checked:true}
];
$.fn.zTree.init($("#allLinesTree", $.pdialog.getCurrent()), setting, treeNodes);
