流程上希望只有本部门的领导可以审批，请问应该怎么实现啊

已解决，谢谢了

解决的方案如下：
var deptProcess = createProcess("cn.myapps.core.department.ejb.DepartmentProcess");
var roleProcess = createProcess("cn.myapps.core.role.ejb.RoleProcess");

var roleVO = roleProcess.doViewByName("部门领导",getApplication());
var roleid= roleVO.getId();
var dptid="";
var author = getCurrentDocument().getAuthor();
println("author111000000======"+author);
if(author!=null&&author!=""){
     dptid=author.getDefaultDepartment();
}
println("dptid000000======"+dptid);
//var deptVO = deptProcess.doView(dptid);
//var sDeptVO = deptVO.getSuperior();

var users = getUsersByDptIdAndRoleId(sDeptVO,roleid);

var userList = createObject("java.util.ArrayList");
if (users !=null)
for(var iter=users.iterator();iter.hasNext();){
   var user=iter.next();
   userList.add(user);
}
}
userList;
