2.2 SpecChange 规格变动
2.2.1 Situation 情景
A company requires approval from three departments, Automation, Manufacturing, and Quality,
for every specification change to its production system. When submitted, the specification
change should immediately appear in Automation's and Manufacturing's 'Inbox's for Approval.
However, the specification change should not appear in Quality's 'Inbox' until the other two
departments have approved it.
对于每个产品系统的规格修改，一个公司需要得到三个部门的批准，自动化，制造和
质量。当规格修改的请求被提交时，规格修改将立即出现在自动化和制造部门的收件箱中
等待批准。然而，规格修改不应该出现在质量部门收件箱中，直到其他两个部门批准它以
后。
To simplify this example, rejecting a specification change will not be required.
为了简化这个例子，不需要否决一个规格。(例子中没有考虑这种情况)

directory of the Java installation. Start the PowerFolder server by going to the directory then go
to the 'jboss' subdirectory then again go to the 'bin' subdirectory. Run program
'run_with_tomcat.bat'.
启动PowerFolder服务器。如果你在安装时配置了环境变量JAVA_HOME，只要在资源
管理中双击run_with_tomcat.bat。否则的话，打开一个命令控制台，设计环境变量
JAVA_HOME到Java安装的根目录。要启动PowerFolder服务器，移动到安装目录，到
jboss子目录，到bin 子目录，运行程序run_with_tomcat.bat。

2.2.5 Results结果
Go to the PowerFolder console and open 'Administer'. Under the 'Existing Workflows' section
click the 'Find Workflows' button.
移动到PowerFolder控制台，打开'Administer'.在'Existing Workflows'部分下，
单击'Find Workflows'按钮.
Now that you are at the 'PowerFolder Query Workflows' web page, change the contents of
'Query' to '*APP* = 'SpecChange'' (note that you should surround SpecChange with single
quotes) and 'Output' to '*ID*,*APP*,*STATUS*,?Change?' (pay attention to letter case and
don't use any spaces!), then click 'Submit'.
现在你处于 PowerFolder工作流查询页面，更改'Query'的内容为'*APP* =
'SpecChange''(注意你应当用单引号来环绕SpecChange）而且'Output'的内容为
'*ID*,*APP*,*STATUS*,?Change?'，注意字符的大小写而且不要使用任何空格，然后单击
'Submit'(提交).
You should see just one listing - the workflow resulting from the test you just ran. The listing
should contain a unique id (each workflow gets its own), 'SpecChange' for the script name,
'DONE' for its status, and 'This is a test' for Change. 'Change' is an application-specific attribute -
an attribute specific to the 'SpecChange' script. Application-specific attributes are represented by
their name surrounded by '?'.
你应当仅仅看到一个列表—那个你刚刚运行的测试产生的工作流。列表中应当包括一
个唯一的序号（每个工作流都有它自己的），脚本名称是SpecChange，它的状态是DONE,
和This is a test作为Change.'Change'是应用特定的属性-一个特定于'SpecChange'脚
本的属性。应用特定的属性被用?号围绕来表示。
Now click the 'Snapshot' button. This will open a new window which will allow you to get much
more detail about the current state of this workflow.
现在单击'Snapshot'按钮。这样将打开一个新窗口，通过它你可以得到更多的关于这
个工作流的当前状态的细节信息。
Click 'Attributes' to see all system and script-specific attributes and their current values. Under
'Script' click 'View Graph' and 'View Summary' to get a nice pictorial and written summary of
the script. Click 'Trigger' to see the data that actually started the process. This data is the XML
element 'powerfolder' containing the test 'This is a test'. Finally, click 'History' and you should
see 'Trace 1' and 'Trace 2'. SpecChange 'branches' (goes in two directions simultaneously) at
'StartHere'. Only one branch reaches 'NotifyQuality', and it is the branch whose department
approves last. In this case, the branch containing 'ManufacturingApproves' should go to
'NotifyQuality' since Manufacturing was not the first department to approve.
单击'Attributes'来看所有的系统和脚本特定属性和它们的当前值。在Sript下单击
ViewGraph和View Summary来得到一个图形和文本书写的关于脚本的总结。单击Trigger
来看实际启动过程的数据。这个数据是包含This is a test的powerfolderXML元素.最
后，单击'History'你将看到Trace1和Trace2。在StartHere，流程SpecChange分支了
（同时走入了两个方向）。只有一个分支到达NotifyQuality，这是最后批准部门所在的
分支。在这个例子中包含ManufacturingApproves的分支应该到达NotifyQuality，因为
制造部门不是第一个批准的部门
