The missing translation leads to an incorrect rendering of the ```select box``` with id ```product_product_category_ids```. ``` <select class="chosen" multiple="multiple" data-placeholder="<span class=" translation_missing"="" title="translation missing: de.shoppe.product_category.choose_product_category" style="display: none;">Choose Product Category" name="product[product_category_ids][]" id="product_product_category_ids"&gt;     <option value="1">Option1</option>     <option value="4">Option2</option>     <option value="5">...</option> </select> ``` Hence, you are not able to create a product because the transfered parameter ```product_category_ids=>[""]``` doesn't contain any values although you have selected options from the select box.

```
<select class="chosen" multiple="multiple" data-placeholder="<span class=" translation_missing"="" title="translation missing: de.shoppe.product_category.choose_product_category" style="display: none;">Choose Product Category" name="product[product_category_ids][]" id="product_product_category_ids"&gt;
    <option value="1">Option1</option>
    <option value="4">Option2</option>
    <option value="5">...</option>
</select>
```
Hence, you are not able to create a product because the transfered parameter ```product_category_ids=>[""]``` doesn't contain any values although you have selected options from the select box.

By adding the appropriate translation, the following output will be generated ...
```
<select class="chosen" multiple="multiple" data-placeholder="Produktkategorie auswählen" name="product[product_category_ids][]" id="product_product_category_ids" style="display: none;">
    <option value="1">Option1</option>
    <option value="4">Option2</option>
    <option value="5">...</option>
</select>
```
Now the selected options are passed to the controller in the correct way.
