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.
