Answer 1

Expression org.userObject is undefined on line 102, column 29 in base/views/org/orgInfoMain.ftlorg.userObject 表达示没有被找到，，

Answer 2

这种错误一般是struts2的标签没有用对 贴出你的代码 标签那里

Answer 3

这是ftl的内容：
<#list treeIterator as org><#if !(org.parent?exists)>
<script language="JavaScript">
myObject = new Object();
myObject.leaf=${org.leaf?string};

myObject.top=0;
myObject.bottum=0;

myObject.userSize=${org.userObject.users?size}; 这地方的错误，说是userObject 没定义
myObject.projectSize=${org.userObject.projects?size};

mTreeData.addTreeNode('c${org.userObject.id}','0',
                    new Array("${org.userObject.name}",
<#if (org.userObject.userSize>0)>
