Editing form creates additional record instead of updating existing one

[asok]

When someone wants to edit existing user in the test application and clicks ok, the new task is created and added to tasks instead of updating existing ones. The reason of this is hash parameters passed to controller from view:
{"commit"=>"ok", "authenticity_token"=>"ISoWFJusyNkCQBxN4cl4B2rRGayYLf3CewRqB/C6O2g=", "id"=>"13", "user"=>{"nick"=>"6 november", "tasks_attributes"=> {"40"=> {"title"=>"", "due_to(1i)"=>"2009", "due_to(2i)"=>"3", "due_to(3i)"=>"6", "description"=>""}}}}
the number 40 as the key is an id of the editing task. But it does not do the trick. Good idea would be to try and see how native rails helpers handle editing nested attributes.

This should be fixed but need testing. If someone wants to test it please add the comment "working on it" or something like this. Feel free to contact me if you have any questions.
