@edvin Yeah, sure. I have Type1Model and Type2Model. Actually I asked the wrong question - the right one would be how to bind the item of Type1Model and item of Type2Model. I have several labels and the text in each of them is a method from first item applied to second item. And also I need a tableview, where the tablerows are the result of applying the method of first item to second. So what is the best way to make such labels and tableview?
