checkout_index_index.xml Breaking when overwriting

Question

I'm trying to overwrite checkout_index_index.xml under module-checkout

It is currently using the file I have created in my theme but the shipping selection is breaking and now showing prices or reloading on zip code change.

I have copied the whole file from the default theme so it's not my code but maybe something isn't including like I found the discount item wasn't working.

So I had to add that manually but can't seem to find whats breaking the shipping any ideas thanks.

Path is

/theme_name/theme/Magento_Checkout/layout/checkout_index_index.xml

Answer 1

So I have not found the problem but I have found a solution

in checkout_index_index.xml in your theme, you can't copy all the content from the default theme but if you want to add stuff to the content section you can use

<referenceBlock name="checkout.root"> 

When using

<referenceContainer name="content">

The shipping table stops working

This is currently my way around it and you can then copy all the info inside

<block class="Magento\Checkout\Block\Onepage" name="checkout.root" template="onepage.phtml" cacheable="false">
....
</block>

From the defult theme and chnage things as you wish i also recomend adding discount to the side bar when overwriting this file as it doenst seem to show the discount if you dont.

<item name="discount" xsi:type="array">
    <item name="component" xsi:type="string">Magento_SalesRule/js/view/cart/totals/discount</item>
    <item name="config" xsi:type="array">
    <item name="title" xsi:type="string" translate="true">Discount</item>
</item>
