Aha, I found the bloody mouse :) On the dashboard when creating a weight base shipping methods you have to put a value on the Maximum Weight. After doing that and overriding the shapes everything works now. Thank´s for your help. You can close this one. Nuno

About the shipping calculations: I create Weight Based Shipping Method on the dashboard and chose all destination areas availables. I created a product on the dashboard and put a value on the weight. Shouldn´t the cart show the estimate shipping price after choosing the country and zip code? I checked on your site nwazet.com and it does that.

So you are saying i should upgrade to orchard 1.7 or keep orchard 1.6.1 and use the latest version of your module? By the way, does the latest version of your module work on orchard 1.6.1?

Clay isn't in Orchard anymore. With 1.7 so close, I won't invest time in fixing this, sorry. Not sure what you mean by "shipping calculations". If shipping methods are not listed, maybe they don't apply to what's in the cart.

Hello Bertrand, I override the the shape and checked for nulls on Model.Country and Model.ZipCode, then i had another error on ShippingInfoForm.cshtml :

Operator '==' cannot be applied to operands of type 'string' and 'ClaySharp.Clay'

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: Operator '==' cannot be applied to operands of type 'string' and 'ClaySharp.Clay'

Source Error:

Line 12:

@T("In order for us to estimate your shipping costs, please let us know where your package should be sent.")

Line 13: @Html.Label("Country", T("Destination country")) Line 14: @Html.DropDownList("Country", Country.List.Select(c => new SelectListItem { Line 15: Text = c, Line 16: Selected = c == Model.Country

I override this shape as well, checking for nulls, and casting Model.Country to string, it worked with no errors, now i can select country and assign a zipcode and the values are stored in localstorage (they display on the form, and i also checked localstorage on Chrome developer tools), but it doesn´t list the shipping methods neither the shipping calculations.

Nuno.

I'll do that asap. I' m going to have some dinner , in an hour and half i'll give it a try and feedback.thank's

OK, I'll try those on a new instance. In the meantime, you can override the shape in your theme and add some explicit null checks.

• Downloaded the module from bitbucket and put it in modules folder of a clean orchard instalation.
• on the dasboard i enabled nwazet.commerce, shipping, attributes, and checkout. *on the dashboard create a shipping provider based on weight.
• on the dasboard create a product (put a value on the weight property).
• on dashboard assigned the shopping cart widget to the asidesecond zone.
• on the front end i go to the product url
• on the product page added the product to cart.
• on the the cart widget going for checkout or viewcart link the error comes in shoppingcart.cshtml.

The problem is that I cannot reproduce your problem. Please provide exact repro steps. (yes, I am using 1.7 on my dev box, and 1.6.1 in production for the moment)

you are using orchard 1.7? is it stable enough for production?

[bleroy]

Original comment by nduarte (Bitbucket: nduarte, GitHub: nduarte):

The first problem is that when you never assign the properties Country an ZipCode to the shape unless the variables country and zipCode passes the validation of Country.UnitedStates or Country not null, when the user goes for the cart page for the first time these are not set, so there is no way for those properties to be set on the shape.

Do you have shipping methods defined?

I'm using the latest on the site. What are your exact repro steps?

Hi Bertrand, I've been debugging the code and i found a problem in ShoppingCartController.cs in the method BuildCartShape, you are only setting on the shape the Country and ZipCode if its not null, or if the country is United States. I Hardcoded the values on the method for testing purposes and the error disapeared, the cart form is shown, but the shippingMethods is returning 0, so i cannot see or access the shipping options.

I see that you have this working well on your website nwazet.com, what version of the module are you using there?

Thank´s

Nuno

Seems like a completely different issue. Please file a separate bug for that, specifying the version of IE you're using.

By the way, i also tried Internet explorer, when i click add to cart button, i get this error : Error: 'JSON' is undefined

I did that already. I´m using orchard v.1.6.1.0 and Nwazet.Commerce changeset 35ef4e256360. Thanks
