Hello Christian,
Here's the removeDeck() function from DB.js:
function removeDeck(deckLanguage, deckColor) {    var tempContents = {};    tempContents = deckDB.contents;    for (var i = 0; i < tempContents.decks.length; i++) {        if (tempContents.decks[i].deckLanguage == deckLanguage && tempContents.decks[i].deckColor == deckColor){            tempContents.decks.splice(i, 1);            break;        }    }    deckDB.contents = tempContents;}
and in the Dialog, I just call PopupUtils.close(); mainStack.pop() and DB.removeDeck(). I think the problem might be in the Repeater, although I am not sure.
