Yup - was just curious as to why changing the order was causing issues. I
had a similar problem on another object where a field immediately following
a pair was causing display errors if it was an integer field eg:
Obj1: make object! [
var1: 0x0
var2: 1
var3: make get-style 'face [
...
]
...
]
This would also seem to build correctly but on creating a new object with
make obj1 [] the var3 would be ignored and often weird errors would result -
I had one case where a pair was being assigned to an object, seemingly from
nowhere. I swapped the order of 2 custom variables I had defined and was
surprised to find that it now worked.
Go figure ;-)
