Boolean must be compared to true or false

[eygraber]

If I have a rule that says:

!next.some_boolean

blaze outputs:

!newData.child('some_boolean').val()

but when I try to add that to my forge's rules I get an error saying:

! only operates on booleans.

I think the issue is that .val() can return any type - not just known boolean values. As a work around, you could write:

next.some_boolean != true

which would translate to:

newData.child('some_boolean').val() != true

[eygraber]

I've been using :

next.some_boolean == true

and :

next.some_boolean == false

but it seems a bit clunky

Agreed. It's a bug...
