Maybe I was not clear in asking my question. I am wondering why it shows EditRole data when I was expected to see DiplayRole data (in the drop down list, for example) or why does it show DisplayRole data in the edit field, moreover, I have different results depending on the order of data assignment to EditRole and DisplayRole. If you swap 16th and 17th line of my code you will get different results, that appears to be strange to me. Where model/view convention explains this?
