I have just patched my Magento 22.214.171.124 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?
