问题描述

我正在尝试设置过程变量，但低于错误

I am trying to set the process variable but getting below error

java.lang.IllegalStateException: Process instance 10[SampleBusinessProcess] is disconnected.
at org.jbpm.process.instance.impl.ProcessInstanceImpl.getProcess(ProcessInstanceImpl.java:100)
at org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.setVariable(WorkflowProcessInstanceImpl.java:343)

这是我的代码-

ProcessInstance processInstance = runtimeEngine.getKieSession().getProcessInstance(processInstanceId);
((WorkflowProcessInstanceImpl) processInstance).setVariable("myvariable", "myvalue");

请帮助我以最佳方式设置过程变量.

推荐答案

我无法对上一个答案发表评论，所以我将发布此答案.

I can't comment on the previous answer so I'm posting this answer.

我发现的快速而肮脏的方法(从先前的答案中得到启发)是:

The quick and dirty way I found (inspired from previous answer) is:

public void setProcessInstanceVariables(long processInstanceId, Map<String, Object> variables) {
    kieSession.execute(new SetProcessInstanceVariablesCommand(processInstanceId, variables));
}

非常感谢Kris Verlaenen！
