java.lang.ClassCastException: com.xmeport.common.entity.auth.proxy.CfCorpProxy cannot be cast to com.xmeport.common.entity.auth.proxy.CfCorpProxy$CfCorpProxyFetcher

```java
eq.queryable(CfCorp.class)
.select(o -> o.FETCHER.corpid().corpSname().corpparentid().corpPath().classflag())
.orderBy(o -> o.corpSname().asc()).toList();
```

Start by reproducing the query shown for CfCorp and inspect the definitions of CfCorpProxy, CfCorpProxyFetcher, and FETCHER. Trace where the ClassCastException occurs and compare the generated proxy type with the cast target. Done means the query completes without this exception and the selected fields and ordering still work.
