Printing Calendar Metadata through rolling calendar page

Is it possible to expose and print metadata from single calendar events, when they are being listed with a rolling calendar page? I used %asset_metadata_<field>%


I tried it, and it worked, BUT, I get tons of mysource errors:

    PHP Warning
    File:	[SYSTEM_ROOT]/core/include/metadata_manager.inc	Line:	627
    Message:	Illegal offset type
    Backtrace:	Show


Was it a problem in the way I executed this, or a bug?
