This bug is just one facet of stored routines not being able to detect changes in meta-data (WL#4179). This particular problem can be triggered within a single session due to the improper management of the pre-locking list if the view is expanded after the pre-locking list is calculated. Since the overall solution for the meta-data detection issue is planned for a later release, for now a workaround is used to fix this particular aspect that only involves a single session. The workaround is to flush the thread-local stored routine cache every time a view is created or modified, causing locally cached routines to be re-evaluated upon invocation.
