Troubleshooting: InterestItemAdd returns no response when invalid parameters are received
There is a limitation when calling the InterestItemAdd command using AJAX calls in the storefront, for example, AjaxInterestItemAdd.
If the updateable
attribute is set to
0, an error message is not displayed when a customer attempts to add
a wish list item that already exists in the wish list.
To avoid
this issue:
- The default behavior should be kept, where no error message is shown when a repeated item is added to the wish list.
It is treated as a successful addition to the wish list, although the item already exists in the customer's wish list.
