Strange behavior on properties. #271

Open tomyo opened 8 years ago

tomyo commented 8 years ago

I'll just paste the self-explained code below: P.S. I tried setting a new value instead of using reset(), same strange behavior.

Template.cartItem.viewmodel
  shippingPrice: undefined
  updateShippingPrice: ->
    if @ship() and not @outOfStock()
      Meteor.call 'calculateShipingPrice', @productId(), (error, result) =>
        if error
          FF.helpers.showInternalError error
        else
          @shippingPrice result
    else
      @shippingPrice.reset()
      @shippingPrice()  # FIXME: Why doesn't work without this line?
                        # shippingPrice doesn't update if I don't ask for it's value now

I don't understand the problem. Please make a minimal repro, preferably without Meteor calls and anything not germane to the problem.

Thanks.

shippingPrice doesn't update if I don't ask for it's value now
