Or, a klever hacker would realize that they should just define a
setter for the parent password attribute that applies the setting
where it is actually needed (saving the overhead of events that the
person who wrote the $once constraint was trying to avoid). I.e.,
'push' the password field to where it is needed.
[cc-ing John. there is probably a place in the docs for the following:]
Remember Adam's first principle of constraints: "They are really
handy for rapid prototyping, but eventually you want to eliminate them."

If you look in the edittext component, it says the internal text field

lps/components/lz/edittext.lzx:
<_internalinputtext name="field"
password="$once{parent.password}"
So the internal field is not looking at the parent.password value more
than once at init time.
That could be changed to an 'always' constraint, I imagine that would
work better.

Hi all, I think i may have found a bug in the edittext component,
but i
thought someone might show this to be correct behavior in a way I
don't yet
see. The issue is setting password="true" on an <edittext/>
component. It
doesn't seem like the password attribute can be constrained. This
example
might also reveal a bug with $immediately{} constraints wherein
"classroot"
and "parent" don't exist when the constraint is evaluated.
Anyone have advice on how to make this work?
Test case: none of these fields (save the last hardcoded editext) has
password styling.
