我正在休息调用IBM Cloud BPM.有时调用工作正常.但有时它会给出以下错误.

java.io.IOException: An existing connection was forcibly closed by the remote host.

java.io.IOException: An existing connection was forcibly closed by the remote host
    at sun.nio.ch.SocketDispatcher.read0(Native Method)
    at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:43)
    at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:223)

任何人都可以帮我解决这个问题.

任何帮助是极大的赞赏.

从http://www.omg.org/spec/BPMN/2.0.2/PDF(第238页):

如果Process用作全局Process(可以从其他进程的Call Activities调用的可调用进程)并且有多个None Start Events,那么当flow从父进程转移到全局进程时,只有一个进程将触发全局流程的启动事件.可以扩展传递给Call Activity对象的Sequence Flow的targetRef属性,以识别适当的Start Event.

如何扩展targetRef属性？它不一定是有效的IDREF吗？也许他们的意思是应该使用自定义属性扩展sequenceFlow元素？

有这种延期的例子吗？现有的BPMN工具是否支持它？

这是我手工编辑的BPMN片段,用于说明问题:

我正在尝试将 BPM 特定的 $WSSR 标头映射到 nginx 配置中的 Host 标头，但我继续收到“nginx：[emerg] 未知的“wssn”变量“错误。如何在 nginx 配置中访问此标头值？有没有办法转义 $ 字符？

这是我当前尝试将自定义标头和主机映射到单个值的配置

map $http_\$wssn $x_host {
    default $host;
    "~." $http_\$wssn;
}

使用此地图重新加载我的配置会导致此错误

# nginx -s reload
2019/08/12 18:37:42 [emerg] 25091#25091: unknown "wssn" variable
nginx: [emerg] unknown "wssn" variable

在BP3 Brazos工具包中,当我'date time picker'用来输入日期和时间时,应绑定哪种类型的变量？

我尝试了绑定日期和datetimepickerselection类型.两者都不起作用,抛出一个错误.
