I think I built the data model according to the documentation, however, my page with the widget does not load with error message “Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined.”. Where should I look from here? Mendix 7.23.4 (cannot find it in the list of versions)
Miroslav Samoylenko DO NOT USE
I'm also working with this board, but i have the same problem.
