searchlogic+date_select+ordering

hi there,

i try to use searchlogic to find entities by date. its working if i just try to search something. the ordering helper is also working if i just show all results. if i want to order (lets say by zipcode) and find by date it wont work. the order helper messes up the params[:search] in case of using a date

if i just search something the params look like (good): Parameters: {"commit"=>"Finden", "search"=>{"date_like(1i)"=>"2010", "date_like(2i)"=>"6", "zipcode_like"=>"", "date_like(3i)"=>"24"}}

if i try to order the results by clicking the order helper link the params look like (bad): Parameters: {"search"=>{"order"=>"ascend_by_zipcode", "date_like"=>"2010-06-24 00:00:00 UTC", "zipcode_like"=>""}}

if i manually set the params its working as well. http://localhost:3000/dinners?search[order]=descend_by_zipcode&search[date_like(3i)]=24&search[date_like(2i)]=6&search[date_like(1i)]=2010&search[zipcode_like]=&commit=Finden

so, just the helper does something wrong with the date params. i have absolutely now clue, iam also very new to ruby/rails.

does anybody know how to get this working?

thanks for any help chris
