[REBOL] Text field mysteries

Hi, all

I'm creating a text field which will display in a different color with
the text "Required!" for an address form.

The code:

view layout [
   name-field: field [
     either any [
       0 = length? name-field/text
       equal? name-field/text "Required!"
     ][
       name-field/text: "Required!"
       probe name-field/text ; shows up blank sometimes!
       name-field/colors/1: 255.150.50
     ][
       name-field/colors/1: 240.240.240
       name-field/font/color: black
     ]
     show name-field
   ]
]

When run, "Required!" is supposed to be displayed after you've skipped
through the field, but forgot to enter information. This works, if the
you don't enter anything and the field isn't dirty?.
When you enter something, that'll be displayed in the correct color, but
if you delete it again, I want "Required!" to be displayed again, but
only the color is correct, the field is blank. Probing name-field/text
gives "" just after I've set it in the code.

If I escape and do a

name-field/text: "Required!"
show name-field

manually, "Required!" shows fine. The behavior matches the contents of
the dirty? flag, but if I set it to none, the behaviour stil continues.
What's wrong?
