osworkflow的一些问题

Question

这是什么原因呢？
workflow.doAction(flowId, 1, map);这句可以正常执行
workflow.doAction(flowId, 2, map);就不可以了

Answer 1

最近几天没来,所以没看到你的贴子，关于你遇到的错误，最可能的原因是actionid = 2 里result使用了join方法，但在你的xml中根本没有join的相关定义,大多数情况下，我们都可以不用join的功能，你只需要好象action 1 一样，定义action 2 完成后，将会跳转到第n个step就可以了. 
如果你想试一下join,则必须在你的xml中定义joins 节点
例子
<joins>
<join id="1">
<conditions type="AND">
<condition type="beanshell">
                                    ....
</condition>
</conditions>
<unconditional-result old-status="Finished" status="Underway" owner="test" step="2"/>
</join>
</joins>

Answer 2

什么意思? 你的项目中定义了很多工作流xml文件吗? 说详细点.

Answer 3

flowId = workflow.initialize("DefaultWorkFlow", 10, null); 
就是这个不是可以创建很多个流程么
比如，申请请假，通过审批
一个人要请假 等待审批 这是一个流程
又有一个人请假 又一个流程
。。
类推多个人请假那么审批的人就要得到这些要请假的人进行审批
怎么得到这些已经创建好的流程呢

Answer 4

就是我要得到OS_HISTORYSTEP的所有记录 怎么得到呢

Answer 5

两种方法:
1.调用workflow本身的函数.
详细例子见自带example中的test.jsp 及 underway.jsp 
underway.jsp 列出未完成的工作流test.jsp 则列出某个工作流的当前操作及历史操作2.直接访问workflow 数据库默认的情况下以下两个表会有你需要的信息
os_currentstep 列出当前所有工作流的当前工作状态
os_historystep 列出已经完成的操作(步骤)直接写sql语句就可得到你想要的信息.
个人觉得直接访问数据库会方便一点，当然要你对数据库熟悉才行. 如果对权限有特别的定义，还是需要用test.jsp的方法来取得可用的action比较安全.

Answer 6

呵呵 问题暂时解决了，我使用sql从数据库取的
先不结贴啦，没分啦 后天之前还没有问题 再结  谢谢你啦

Answer 8

你是如何跑action=2 的? 用doaction吗? 把代码贴出来看看

哈哈 问题都暂时解决啦 谢谢啦
有的时候在call你呀
