Cart summary disappears when clicking "continue shopping" (PS 1.7)

[creation-handicap]

I show the cart summary on my product page. When I add something into the cart and then click "continue shopping" in the following popup, the cart disappears.

 

Somebody has a solution for that?

It seems, there is an error in the themes/core.js on line 1730. The resp returns the HTML of all the page. So the variable e.g. resp.cart_detailed_totals is undefined.

But i don't know how to fix that...

Update: It seems that the cart is not build to put it on every page. This is why, my guess, that it doesn't work. I fixed it with an hardcoded URL for the getCartViewUrl variable. It's not a good soluation, but it works now...

Here's the code i put into the core.js on line 1724:

if (getCartViewUrl === undefined) {
	getCartViewUrl = '{URL-to-your-page}/de/warenkorb?ajax=1&action=refresh';
}

This is most probably different in other languages...
