Undefined array key "optGroup0"

[mdius]

Now I am getting a "Undefined array key "optGroup0"" /packages/community_store/src/CommunityStore/Product/ProductOption/ProductOption.php

if ($option) {
    //add option items
    $itemsInGroup = is_array($data['optGroup' . $i]) ? count($data['optGroup' . $i]) : 0;   <- Error Line 315

    if ($itemsInGroup > 0) {
        for ($gi = 0; $gi < $itemsInGroup; $gi++, $ii++) {
        if ($data['poiID'][$ii] > 0) {
              $optionItem = ProductOptionItem::getByID($data['poiID'][$ii]);

I fixed it by changing the line to: "$itemsInGroup = isset($data['optGroup' . $i]) && is_array($data['optGroup' . $i]) ? count($data['optGroup' . $i]) : 0;" I don't know if that is the proper way, but it is seeming to work.

I'd say that's the best way to address this for now, I've pushed that up to the master branch.

Why it's undefined in the first place is perhaps a better question to ask, but if it's all saving and working as expected there might not anything to fix as such.
