The offset was being set to a negative when params[:current] is nil on the initial default passthrough. I added a simple check to get the offset back to 0 in that case - there's probably a more elegant solution... <code> # calculate the right offset values for current page and page_size offset = (options[:current].to_i - 1) * options[:page_size] offset = 0 if offset < 0 # was seeing "LIMIT -X,X" by default </code> Ilya, I was seeing the LIMIT -X,X behavior as well (same as Yves back in Jan07).

# calculate the right offset values for current page and page_size
offset = (options[:current].to_i - 1) * options[:page_size]
offset = 0 if offset < 0 # was seeing “LIMIT -X,X” by default

I was passing in get variables that were hashes and paginating_find doesn't support those. I've changed my form so that it doesn't submit those and it's working great. Thanks for the code Ilya!

If so, you could run a UNION query and then do a pagination on that. It gets a little trickier, but theoretically, it is possible.
