In a data grid there is the option "select first". For a listview this would be a very good option to add in the modeler, in the "adit list view" pop-up.
When an data view listens to a listview, it exacly knows which item it listens to. However, when the page is viewed, the listen to grid does select the first, but the listview does not have the option to select the first, so none is selected. Also, when a listview item is added, the selected class is unfortunately lost. For me it will save a lot of time when the class "selected" will be kept.
The "selected" class on the first listview items was actually present in older versions of Mendix and has disappeared in Mx6.4. Probably as a byproduct of the perfomance improvement for list views in that release.
