Problem with optional type:<#class>

#1

In maxscript help it´s said that optional type:<#class> specifies that the parameters in the parameter block are “class” parameters. I tried it in my plugin parameter block:

...
myVar type:#class
...

but when I try to run this code, geting an error mesage about some problem with type:#class.

#2

it’s a known bug… it’s never worked. forget it as if it doesn’t exist
