I found all reference's source is Ryan Bates nested form exmaple,based in github. but in rails3,i came crome this view [1]. it's all sucks.
the cause reason is the hidden temple default value is false.when sumit action,the hidden values will not discard,and continue update this params.
i see the log,i think maybe some validation is wrong. oh,i found the original accepts_nested_attributes_for is
reject_if => lamda {|a| a.values.all?(&:blank?)}
this is blocker question.
i change the evalution assert to :
reject_if => proc {|a| a[:name].blank? }
attention,the:name is task's attribute name.
this is indicate original code is not working on rails3.
this is all.done.for your convinent test,i have attached my sample deme.have a try.
