<html> <head> <style></style></head> <body class='hmmessage'><div dir='ltr'> Hi Matthias, As promised, below is the patch demonstrating the issue. One thing I lied was its not enum that I missed but I missed one of the data objects extended. ------------------------------ <pre> Patch is only to demonstrate the misleading error warning if one extended data objects is not defined and an attempt to "CastFromAny" is done on the base object. HostHostBusAdapter is extended by: HostBlockHba, HostInternetScsiHba, HostFibreChannelHba and HostParallelScsiHba. In this demo, definition of HostParallelHba is missing from esx_vi_generator.input.
