Change Handlers and modifier attributes (MaxScript)

[stalkerportal1]

seems like Change Handlers is broken in max 2021.1 for modifiers attribute - "name" (in max 2016 - 2019 works)

example:

obj = box()
deleteAllChangeHandlers id: #CH_test
modif = Bend()
when name modif change id:#CH_test do
(
print "1"
)
addModifier obj modif
select obj

-----------

Changing modifier name from modpanel not trigger change handler. With objects works - ok, but not with modifiers.

that this does not work is very unlikely ... you are doing something wrong.

try execute:

(
	b = bend()
	h = when name b changes do (print ("name:" + b.name))
	b.name = "the bend" 
)

it must return:

"name:the bend"
"the bend"

does it work? it has to print on Undo/Redo as well

I checked it in max 2021.1 and change handler not works as expected 😞

max 2021.1 result(not correct):

max 2019.3 result(correct):

This is very bad. Autodesk should tell us what is going on.
