xtree使用的问题

在xtree使用过程中，遇到了这样一个问题，就是在点击一个节点的时候，要ajax请求返回json数据然后生成下一级树，但是当客户再次点击该节点的时候，xtree同样还是把刚才的子节点重现加载一遍，这样该节点下的子节点就重复了，代码如何
var tree = new WebFXTree('测试', 'javascript:\" onclick=\"return false;');
tree.setBehavior('classic');

//将返回的json数据动态生成树
var showTree = function(data){
    if (data != null && typeof data == 'object') {
        for (var i = 0; i < data.organizationViews.length; i++) {
            if (data.organizationViews[i].type == 'ORG') {
                if (null == tree.getSelected()) {
                    tree.add(new WebFXTreeItem(data.organizationViews[i].organization.organizationName, 'javascript:\" onclick=\"javascript:findOrg(' + data.organizationViews[i].organization.organizationId + ');'));
                }
                else {
                    tree.getSelected().add(new WebFXTreeItem(data.organizationViews[i].organization.organizationName, 'javascript:\" onclick=\"javascript:findOrg(' + data.organizationViews[i].organization.organizationId + ');'));
                }
            }
            else
                if (data.organizationViews[i].type == 'EMPLOYEE') {
                    if (null == tree.getSelected()) {
                        tree.add(new WebFXTreeItem(data.organizationViews[i].employee.employeeName, 'javascript:\" onclick=\"javascript:test(' + data.organizationViews[i].employee.employeeId + ');'));
                    }
                    else {
                        tree.getSelected().add(new WebFXTreeItem(data.organizationViews[i].employee.employeeName, 'javascript:\" onclick=\"javascript:test(' + data.organizationViews[i].employee.employeeId + ');'));
                    }
                }
        }
        tree.expandAll();
    }
    document.getElementById("rogPanel").innerHTML = tree.toString();
}

//根据父节点查询下一级的组织机构
function findOrg(organizationId){
    var url = "organization!getOrgJson.do";
    $.getJSON(url, {
        orgId: organizationId
    }, showTree);
}

我也遇到过这个问题，你可以判断下 当再次点击它的时候就不再发送请求了.
