代码

        TaskQuery todoTaskQuery = taskService.createTaskQuery().taskAssignee(user.getLoginname()).active()
                .includeProcessVariables().orderByTaskCreateTime().desc();

忽略掉execution属性试试

@Ok("json:{ignore:'execution'}")

@wendal

   @At("/tododata")
    @Ok("json:{ignore:'execution'}")
    @RequiresPermissions("wf.cfg.task")

还是报错同样的

奇怪,为啥还是调用了呢

在Setup的init方法里面加入这些代码试试

        JsonEntity en = Json.getEntity(Mirror.me(TaskEntity.class));
        en.getFieldMap().remove("execution");
        en.getFields().remove(en.getField("execution"));

@wendal 还是报哪个错误

还是getExecution方法？

发现和 execution 有关的 ProcessInstanceQuery TaskQuery 查询的时候都会报错

神奇了，难道不是TaskEntity而是它的子类？debug一下getExecution方法，看看对象的类是什么

TaskEntry不适合直接传到前台, 走VO对象解决
