普元 EOS Platform 7.6 执行人工活动报错：com.primeton.ext.data.common.ValueConvertException: the object class is 'java.util.HashMap' , so cannot convert the object to DataObject.

【问题】

EOS Platform 7.6 人工活动2和人工活动3连线条件为复杂表达式,对相关数据 b的值进行判断（b==1||b==5），表达式书写正确，但执行人工活动2仍报错：

项目经验分享：

问题原因：流程实例相关数据区里有个相关数据a的实际类型和定义的类型不匹配导致，a在相关数据区里是DataObject类型的，而在流程定义期定义的是HashMap类型的；

解决方法：将流程定义里a的类型改为DataObject，以覆盖已有版本的方式重新发布流程定义后，再执行人工活动2就不报错了
