我正在alFresco中构建一个自定义工作流，我正在设置两个执行变量的值，如下所示

<startEvent id="startevent1" name="Start" activiti:formKey="swwf:AssignmentTask">
      <extensionElements>
        <activiti:executionListener event="complete" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">
          <activiti:field name="script">
            <activiti:string><![CDATA[logger.log("Log Start");
                        execution.setVariable('translator', task.getVariable(swwf_translator));
                        execution.setVariable('reviewer', task.getVariable(swwf_reviewer));]]></activiti:string>
          </activiti:field>
        </activiti:executionListener>
      </extensionElements>
</startEvent>

启动任务对应的工作流模型中的类型为

        <type name="swwf:AssignmentTask" >
            <parent>bpm:startTask</parent>
             <associations>
                <association name="swwf:translator">
                    <title>Translator</title>
                    <source>
                        <mandatory>false</mandatory>
                        <many>false</many>
                    </source>
                    <target>
                        <class>cm:person</class>
                        <mandatory>false</mandatory>
                        <many>false</many>
                    </target>
                </association>
                <association name="swwf:reviewer">
                    <title>Reviewer</title>
                    <source>
                        <mandatory>false</mandatory>
                        <many>false</many>
                    </source>
                    <target>
                        <class>cm:person</class>
                        <mandatory>false</mandatory>
                        <many>false</many>
                    </target>
                </association>
          </associations>
        </type>
