Question

Hybris：产品驾驶舱在集合的比较模式下抛出ClassCastException。在正常模式下，它工作正常。

如何将MyTypedObject显式转换为集合？

我的代码段：

Collection<CategoryModel> pCategories = ProductModel.getSupercategories();
  for (CategoryModel parentCategory : pCategories) { //ClassCastExceptionthrown
            //do something
  } }

堆栈跟踪：

Answer 1

从特定的产品中查看HMC，它具有完全超类别。据我所知，超类别不必总是来自 CategoryModel 类型。您似乎已使用 MyTypedObject 扩展了 CategoryModel 。

以前你必须在这里做检查。类似的东西：

if (parentCategory instanceof ...)

Hybris产品驾驶舱比较模式MyTypedObject ClassCastException
