Unhandled event loop exception问题

xjy8080

在ontology文件中操作‘添加新关系’或‘从已定义关系中选择’会报以下错误：

界面出现错误信息弹窗：

改如何解决？

jishuang

循环引用了，ontology中引用的其他模块中看看是不是引用了当前的模块

如A模块引用了B模块，B模块又引用了A模块
出现这样需要相互引用的可以创建一个公共的模块如common，在common模块下创建A和B都需要的资源
然后A和B都引用common模块

xjy8080

指的是引用（USE）还是包含(INCLUDE)?

jishuang

都包括

xjy8080

已经按照你上面说的设置了 设置之后就报另外一个错误： 在ontology文件里已经设置了data-type，还要我去设置对应的类型!

jishuang

保存后服务重启一下

xjy8080

重启过很多次了，还是报这样的错！

jishuang

BIZ层右键模型检查看看错误信息

xjy8080

错误信息里没有报出刚才的错误，

jishuang

对应的关系相关的错误也没有？
