The DataViewList will not be updated for Mendix 5. Instead, we have implemented its functionality in the built-in List View widget in Mendix 5.3.1. The ListView has two new features:
Having this functionality built-in makes it much more user-friendly: you do not need to make a page for each specialization, for example. I hope you like it!

Please not this is a experimental fix and I did not fully retested every functionality. If you come across any issue, let me know.
The widget is not updated for Mendix 5.1 yet. The way arrays are passed is changed. File a bug report.
