We’ve implemented the chain of responsibility pattern with definitions. In short this means that for each property a control uses, it goes through the following chain:
This order is important. If the instance property didn’t come first, we would not be able to edit properties through the designers. Values that we set in the Sitefinity CMS page editor would be neglected. That’s why we want to read instance values first.
