Make Product Name longer

[Es Club Shop]

Hello,

I want to make Product name longer than 128 chars. I did many things as changed varchar to 255 in table ps_product_lang and changed this code product.name|truncate:180 in file product-list.tpl (truncate was 45). But doesn't work.

How can I do it?

I did it as in file Product.php changed the line

'name' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isCatalogName', 'required' => true, 'size' => 128)

to

'name' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isCatalogName', 'required' => true, 'size' => 255)
