The instruction to set a bpatcher 'hidden' on and off via thispatcher doesn't work anymore.

I'm not sure which of the previous versions this started happening but I tracked down this error message that started popping up: "patcher - doesn't understand ""

I traced it to my js message to ' UI.getnamed('myBpatcher').message('hidden', num); I then tried it inside the patch holding thebpatcher with a toggle going through a 'prepend script send myBpatcher hidden' and it gives the same error message. I have a lot of 'hidden' toggle messages going to pieces of my UI, and it's the only one giving the error.

Bug?
