Hi,
Now it seems that we have not allowed to register the callback functions
since beta 2010.02.18.
For example:
\startluacode
local old_pre_linebreak_filter = callback.find ('pre_linebreak_filter')
local function my_pre_linebreak_filter (head, groupcode)
if old_pre_linebreak_filter then
old_pre_linebreak_filter (head, groupcode)
end
print ('This is my pre_linebreak_callback')
return true
end
callback.register ('pre_linebreak_filter', my_pre_linebreak_filter)
\stopluacode
\starttext
This is just a test!
\stoptext
The 'my_pre_linebreak_filter' function can not work again. Is this a bug?

I see. The 'pre_linebreak_filter' callback function is frozen.
indeed as otherwise you kick out functionality; there are two user hooks:
tasks.appendaction("processors","before","modules.mine.whatever_a")
tasks.appendaction("processors","after","modules.mine.whatever_b")
as it's impossible to forsee what interference happens it will be clear
that there is no support beyonf this
