I migrated a magento 1 site to magento 2, and checkout (any theme) immediately failed with error:

Exception #0 (Magento\Framework\Exception\RuntimeException): Type Error occurred when creating object: Magento\Eav\Model\Entity\Attribute\Source\Config, Argument 1 passed to Magento\Eav\Model\Entity\Attribute\Source\Config::__construct() must be of the type array, null given

This post how I debugged/tracked down the issue.

Recently I had an issue regarding a site that runs 2 stores, but shared the same ROOT category between the stores, but had seperate categories per store (categories are enabled at store level)

The problem is that the integrated search service ( Algolia ) woudl index all products to all sites. The issue is that you could then search products in one store from another. This is not wnated, as they do have seperate products.

The only reason they sahre a root catalog is that all products do actually belong to both stores, which facilitates the ability to swap between stores, and retain products in cart from each store. So in effect you can checkout in either store with another stores products.

Search, however shoudl not be cross-site

One of our clients was so happy with the outcome of their usage of our Dynamic Category Products extension, they decided to write a not so small review. It was too big to fit into the review aea, so I decided to make it a blog entry.

Thank you for the awesome review Chris.

Ever wanted to create a Gift Promotion for your store to which the customer can add any product, from a specific category, and that item will be gifted (or half price, or any price for that matter)

The latest feature from ProxiBlue Gift Promotions can do exactly that!

A recent task was to integrate a client website with Airbrake.

Simple enough task, sicne Airbrake supplies a working magento module via github: https://github.com/airbrake/Airbrake-Magento

Unfortunately, integration was not as simple as initially thought, due to the Airbrake module and my own Newrelic module clashed in regards to the magento log stream writer. 

Recently, the Google Product Feed for one of my clients simply stopped working (sporadically)

Investigation revealed timeout issues happening during the feed, even though the feed was allowed to run for hours, via settings and code. The problem seemed to occur more often than not, making for poor service on updating their Google Merchant Centre products.

Dynamic Category Products to the rescue! 

The latest new feature in the Gift Promotion extension, is the ability to generate (and email) coupons on the following customer actions:

Newsletter Subscription
Account Create
Birthdays

Import export of Dynamic Category Product Rules has arrived!

Using Exact Target it is very possible to track conversions, using a basic img tag which passes some xml to the tracker.

You can read about how/what is required here: http://help.exacttarget.com/en/documentation/exacttarget/content/conversion_tracking/

Making this work with Google Tag manager is a bit tricky, but very possible

The process can be done in 3 easy steps:

1. Capture the relevant passed params from any cliked url

2. Pass that data to teh datalayer

3. Use the data in GTM

Google Tag Manager allows you to easily send all products to an external resource, by using the dataLayer, and a specific tag.

But what if you want to fire a tag only when a specific product, or set of products, have been purchased?

I worked out an easy way to get it done, using macro's and dataLayer.
