error in ahah_forms.js with jquery_update 2

A small correction that make works the ahah js request (in drupal 5.10) for me

around line 42
// push the name/value of the activated element into the params
substitute
params.push( {name: $(element_id).name(), value: $(element_id).val()} );
with
params.push( {name: $(element_id).attr("name"), value: $(element_id).val()} );

because $(element_id).name() give error because is not a function.

bye lu
