Obviously this is quite an old post, but in case anyone finds themselves here with the error above, the fix is to comment out the following line in your HTML code (pasting it with the comment tag added).  Assuming that you have this problem, you will likely not be able to access your page any longer, so the way to get to where you need to modify is to go in to settings / views and then search for your page.  It will be a qWeb view that you can simply edit and modify.  Then go back to your website view and all should be well. ;)

<!--<t t-foreach="kwargs" t-as="kwarg">

<input type="hidden" t-att-name="kwarg[0]" t-att-value="kwarg[1]"/>

</t>-->

Odoo website works in mvc pattern. So creating view is simply just 1/3 of your needs. You will have to also create controller and edit module for some extra behaviour. To create a well working page do this by creating a new module wit mvc content. If you wan't to just inherit some other page use xpath. Don't forget that you can also use JavaScript w/ JQuery if you wnat to add som fancy things. Everything can be found in original Odoo website, website_sale, website_crm modules.

Hi Harold, 

I had the exact same experience as you did. Please have a look here for a step-by-step guide:

Hope this helps.

Thanks. I have been able to copy/paste the HTML code of the contact us page into my new "Registration" page. But in changing the HTML code of the contact form doesnt it modify the existing simple contact us page as well? That page is still needed for simple contacts.

I see the contact form is linked to the contact us page via an xpath expression:  <xpath expr="//div[@name='mail_button']" position="replace">. Doest the xpath need to be modified in anyway and should i be using the existing contact form or create and new form altogether for new registration form page?

just fyi, I tried creating a new qweb view from  Settings/Technical/Views:

View Name: Registration Form

View Type: QWeb

Inherited View: Registration

And getting this error:
