BCC error while browsing a SKU(s) in ATG10.0.1

BCC error while browsing a SKU(s) in ATG10.0.1 I have migrated from ATG2007.1 to ATG10.0.1. But am not able to access the Product,SKU’s Tabs in the BCC of ATG10.0.1. while accessing the SKU’s Tabs in BCC am getting the error: "java.lang.ClassCastException: atg.repository.dp.DerivedPropertyDescriptor cannot be cast to atg.adapter.gsa.GSAPropertyDescriptor" I removed the derivation property for Internationalization in the customCatalog xml, then tabs are working fine. So I created the ATG ticket and I got the new patch for this issue. After I put the new patch (PR_ASSETMGR-170417_10.0.1_v1_lib.jar) it got fixed. Summary of the problems handled by this hotfix: Flex UI assumes displayName is a GSA property (not derived) and tries to precache it when displaying assets
