magento2 [Issue] Fix dynamic rows dnd array serializer in design config

This issue is automatically created based on existing pull request: magento/magento2#38731: Fix dynamic rows dnd array serializer in design config

Description (*)

When using a dynamic rows component in design config, the save fails because when Magento tries to compare current value with the parent one, an error occurs:

TypeError: Magento\Theme\Model\Design\Config\ValueChecker::isEqualArrays(): Argument #2 ($defaultValue) must be of type array, bool given, called in /var/www/project/magento/vendor/magento/module-theme/Model/Design/Config/ValueChecker.php on line 87 and defined in /var/www/project/magento/vendor/magento/module-theme/Model/Design/Config/ValueChecker.php:100

It's because the argument types are array, but the default value is never caster while it could be null, an empty string or a boolean.

Hello @thomas-kl1,

Thanks for reporting the issue!

We have tried to reproduce the issue in the Magento 2.4-develop instance and it seems the issue is not reproducible for us. We are able to save the dynamic rows and fetch it successfully.

Please refer to the below custom module for reference and let us know if we missed anything: Magz.zip

Thanks

Hello @engcom-Bravo

The problem occurs when you add a dynamic rows to the design config view, not the system config. Field must bee added to ui_component design_config_form.xml.

Hello @thomas-kl1,

Thanks for the reply!

We have tried to reproduce the issue with the design config view, but it seems the issue is still not reproducible for us. I order to reproduce the issue, we have modified the below file:

https://github.com/magento/magento2/blob/91cb4d46834b88bb8dc9f5b06279a63d9ad0963c/app/code/Magento/Theme/view/adminhtml/ui_component/design_config_form.xml#L47

And add the below XML in the other_settings fieldset:

<field name="show_top_information" formElement="select">
                <settings>
                    <dataType>text</dataType>

How did you setup the di.xml part? Mine is:

I do use the Magento\Config\Model\Config\Backend\Serialized\ArraySerialized which is what we need to use for dynamic rows on system.xml

   <type name="Magento\Theme\Model\Design\Config\MetadataProvider">
      <arguments>
          <argument name="metadata" xsi:type="array">
              <item name="top_information" xsi:type="array">
                  <item name="path" xsi:type="string">design/header/top_information</item>
                  <item name="fieldset" xsi:type="string">other_settings/header</item>
                  <item name="backend_model" xsi:type="string">Magento\Config\Model\Config\Backend\Serialized\ArraySerialized</item>
              </item>
          </argument>
      </arguments>
  </type>

Jun 20 '24 19:06 thomas-kl1

Yes @thomas-kl1,

We are using the below setup in the di.xml:

<type name="Magento\Theme\Model\Design\Config\MetadataProvider">
        <arguments>
            <argument name="data" xsi:type="array">
                <item name="top_information" xsi:type="array">
                    <item name="path" xsi:type="string">design/header/top_information</item>
                    <item name="fieldset" xsi:type="string">other_settings/header</item>
                    <item name="backend_model" xsi:type="string">Magento\Config\Model\Config\Backend\Serialized\ArraySerialized</item>
                </item>
            </argument>
        </arguments>
    </type>

But still, the issue is not reproducible for us.

Thanks

I'm still facing the issue on the latest Magento version, could you send me the updated version of your module?

Jul 01 '24 12:07 thomas-kl1

Ok @engcom-Hotel in order to reproduce the issue you need to be on a website or store scope level.

That is because of \Magento\Theme\Model\Design\Config\ValueChecker::isDifferentFromDefault we got into the isEqual method when we are in a specific scope, then we face the error because it tries to compare the default value from the default scope with the current one. The error occurs becaus there's no specified default value in config.xml or set before

Jul 01 '24 13:07 thomas-kl1

I've also noticed an other error when we use a wysiwyg (with the following options:

<item name="pagebuilder_button" xsi:type="boolean">false</item>
<item name="is_pagebuilder_enabled" xsi:type="boolean">false</item>
<item name="toggle_button" xsi:type="boolean">true</item>
<item name="dynamic_id" xsi:type="boolean">true</item>

Setup a single value on default scope. Save.
Setup a second value on store view scope. Save.
The second row is there but the content is empty.

If I add a new row and delete the added row, the content of second row is now visible..

Jul 01 '24 13:07 thomas-kl1

Hello @thomas-kl1,

I'm still facing the issue on the latest Magento version, could you send me the updated version of your module?

Please find attached the module: Magentoissues.zip

in order to reproduce the issue you need to be on a website or store scope level.

We have tried it with the website scope as well, but still unable to reproduce the issue. If possible please provide us with your module in which you can reproduce the issue.

Thanks

Jul 02 '24 09:07 engcom-Hotel

@engcom-Hotel How were you able to test it? I see the di.xml is missing, so you shouldn't be able to save the value

Jul 02 '24 09:07 thomas-kl1

Ok I do reproduce the issue with your code and the following di:

    <type name="Magento\Theme\Model\Design\Config\MetadataProvider">
        <arguments>
            <argument name="metadata" xsi:type="array">
                <item name="show_top_information" xsi:type="array">
                    <item name="path" xsi:type="string">design/header/show_top_information</item>
                    <item name="fieldset" xsi:type="string">other_settings/header</item>
                </item>
                <item name="top_information" xsi:type="array">
                    <item name="path" xsi:type="string">design/header/top_information</item>
                    <item name="fieldset" xsi:type="string">other_settings/header</item>
                    <item name="backend_model" xsi:type="string">Magento\Config\Model\Config\Backend\Serialized\ArraySerialized</item>
                </item>
            </argument>
        </arguments>
    </type>

In order to reproduce:

Make sure that you don't have default value setup for this field in your config.xml file.
Make sure that your don't have any value saved in core_config_data table for this field.
Go to the store view scope directly, add some rows with values, trigger the save.

You will face the error. It's because for the scoped values, Magento always tries to compare to the default scope value, which actually doesn't exists so the type check fails. Change from https://github.com/magento/magento2/pull/38731/files fix it.

Jul 02 '24 09:07 thomas-kl1

The workaround is to setup a default value in config.xml, as explained before (but not ideal).

Jul 02 '24 09:07 thomas-kl1

Thanks @thomas-kl1 for the inputs, we can reproduce the issue now.

@engcom-Hotel How were you able to test it? I see the di.xml is missing, so you shouldn't be able to save the value

I think by mistakenly provided you with the older version of the module.

We are confirming the issue for further processing.

Thanks
