String value of a cell doesn't exists. What is the problem?
I have a question about usage data page for repeat grid and changing cell format. I've got a repeat grid that source data from a data page. Columns on a repeat grid references properties as .pxPages(Class).PropertyName. I got a property of DateTime type and when a Cell control "Inhereted from property" everithing works fine. Now I want to change Date format and trying to change Cell control to DateTime and after that I'm not able to save Section succesfully, error message: "String value of a cell: .pxPages(Class).propertyName doesn't exist or is not a valid entry for this ruleset "
