[Laszlo-dev] delegates *must* have an argument?

[Sarah Allen]

The reference page for Idle doesn't say what it argument is...
http://labs.openlaszlo.org/trunk-nightly/docs/reference/lz.IdleService.html

my guess is the reference is rife with those kind of omissions...  
should I bother to report it?
