Issue after SUPEE-8788 in removing samples downloadable products

Question

I have just patched my Magento 1.9.2.4 with SUPEE-8788. Everything seems to be ok a part an issue in removing samples of downloadable products. I mean when i click the "X" to remove the samples nothing happens

If i check with firebug included in firefox i see an error: "Uncaught TypeError: Cannot read property 'remove' of undefined at Object.remove ((index):2113) at HTMLButtonElement. (prototype.js:391) at HTMLButtonElement.responder (prototype.js:5598)"

Can anyone know why this happens?

Answer 1

I found the solution, this is a bug in SUPEE-8788

Open samples.phtml inside app/design/adminhtml/default/default/template/downloadable/product/edit/downloadable

Find the function

remove : function(event){
    var element = $(Event.findElement(event, 'tr'));
    alertAlreadyDisplayed = false;
    if(element){
        element.down('input[type="hidden"].__delete__').value = '1';
        element.down('div.flex').remove();
        element.addClassName('no-display');
        element.addClassName('ignore-validate');
        element.hide();
    }
},

and replace it with

remove : function(event){
    var element = $(Event.findElement(event, 'tr'));
    alertAlreadyDisplayed = false;
    if(element){
        element.down('input[type="hidden"].__delete__').value = '1';
        Element.select(element, 'div.flex').each(function(elm){
            elm.remove();
        });
        element.addClassName('no-display');
        element.addClassName('ignore-validate');
        element.hide();
    }
},

This will solve the BUG
