Something catastrophic went wrong with the whitespace in your email ...
But I think the problem is in your incrementToken impl: you cannot set
the payload, and then call input.incrementToken, because
input.incrementToken will clear all attributes (including payload).

Hi Karl,
I use payloads for weight only, too, with BoostingTermQuery (see:
http://www.nabble.com/BoostingTermQuery-scoring-td20323615.html#a20323615)
A custom tokenizer looks for the reserved character '\b' followed by a 2
byte 'boost' value. It then creates a special Token type for a custom filt

Thanks for your comments Doron. I found the earlier discussions on the dev list
(21/12/06), where this issue is discussed - my use case is similar to Nadav Har'El.
Implementing payloads via Tokens explicitly prevents the use of payloads for
untokenized fields, as they only support field.string
IIRC first versions of patches that added payloads support had this notion
of payload by field rather than by token, but later it was modified to be by
token only.
I have seen two code patterns to add payloads to tokens.
The first one created the field text with a reserved separator/delimiter
