Potential Dataflow Issue - Updating Non Referenced Fields on Product Import

[henryhayes]

For clarity, this is not about Import/Export. It's about Dataflow.

I have also opened an issue on Stack Exchange to get more exposure. Contributions are invited in either thread.

Summary (*)

There is either a bug or something is configured wrong. What's happening here is that dataflow is un-ticking the "Use Default Value" box on every attribute with website or store view scope when a sku is updated via dataflow for that view.

Examples (*)

Update a product using Import/Export Profile and select a specific store view from the store select and try and import a CSV with name field for example. This will then un tick and copy the default data for every attribute within scope store view for that product and that store view.

Attributes with website scope will also have their values un ticked and data copied from default.

Proposed solution

None as yet.

EDIT:

I'm currently investigating app/code/core/Mage/Catalog/Model/Convert/Adapter/Product.php::save() on lines 764 to 813 as this appears to be the code that is responsible for this.

@henryhayes I don't know you case, but recently found out that app/code/core/Mage/Catalog/Model/Convert/Adapter/Product.php checks for incorrect class type in line 506 and 520.
See #2034
It's a long shot, but maybe sth helpful to you?

For now, I have used the class rewrite to fix it until the fix is merged in. But it doesn't seem to fix my issue.

understood, feel free to push your changes as PR

[henryhayes]

I have no changes to push as it didn't fix my issue.

@henryhayes for now i have dirty fixed this issues with a workaroud, it's tested only for update product's name (other values like visibility are not saved)

i have replaced line 815 with

            if($field != 'sku' && $field != 'id') {
                $product->setData($field, $setValue);
                $product->getResource()->saveAttribute($product, $field);
            }

and comment line 885

//$product->save();

but this is not a clean solution, we have applied this suggestions from this resource:
https://makandracards.com/magento/8281-setting-data-per-store-on-entites/read

hope this is a good strating point to solve this issue

PS: for clean database and restore default values for store view we have used this magerun addon
