[web2py] computed fields question

[Vasile Ermicioi]

hi,

I have a function and a computed field

def content_snapshot(s): 
    #do something with s
    return modified_s


Field("content_snapshot", "text", readable=False, writable=False, 
compute=lambda r: content_snapshot(r['content'])),

and it works only for insert operations,  on updates it is not changed

any thoughts?
