更新jbpm业务规则中的输入变量

Question

我正在尝试在jbpm流程中使用业务规则。业务规则具有与过程变量关联的输入和输出。

我尝试插入参数并将其传递给该过程。该规则将考虑流程的插入值，而不考虑业务规则。我遵循了这个tuto。我认为我正在循环播放一些内容，请您帮忙。

预期的行为是在控制台输出incrementation firing... New Value:2中而不是6中。

以下代码显示了业务规则：

rule "incrementation"
ruleflow-group "incrementInt"
        no-loop
        when
                unEntier : java.lang.Integer()
        then 
                retract( unEntier );
                unEntier++;
                System.out.println("incrementation firing... New Value:"+unEntier);
                insert(unEntier);
end

这就是我所说的过程：

Command c0 = CommandFactory.newInsert(new java.lang.Integer(5));
HashMap<String, Object> h = new HashMap<String, Object>() {
  {
    put("inint", new java.lang.Integer(1));
  }
};
Command c1 = CommandFactory.newStartProcess("test.thirdProcess", h);

kieSession.execute(CommandFactory.newBatchExecution(Arrays.asList(c0, c1)));

这是呼叫输出：

ENTRY: int = 1
11342 [main] ERROR org.jbpm.workflow.instance.node.RuleSetNodeInstance  - Could not find variable scope for variable var_test.thirdProcess_inint
11342 [main] ERROR org.jbpm.workflow.instance.node.RuleSetNodeInstance  - when trying to execute RuleSetNode Task
11342 [main] ERROR org.jbpm.workflow.instance.node.RuleSetNodeInstance  - Continuing without setting parameter.
incrementation firing... New Value:6
11357 [main] WARN  org.jbpm.workflow.instance.node.RuleSetNodeInstance  - Could not find variable scope for variable var_test.thirdProcess_inint
EXIT: int = 1
