Problems with visualization of .gpkg file

[luchengqi7]

I have recently tried to visualize the output .gpkg file from a DRT simulation. The .gpkg file can be loaded properly in VIA, but the attribute type of some attributes are not correctly recognized (e.g., mean waiting time, p50, p95...). Instead of being recognized as Double, they are recognized as String (see first screenshot). This makes it difficult to do the visualization. I am not sure if this is a problem of VIA or the problem of .gpkg writer. As I can see in the DrtZonalWaitTimesAnalyzer, all the attributes should have been written in the correct format.

Furthermore, I also tried to add the .gpkg file as a layer in QGIS. The geometry cannot be displayed on QGIS. But I can still export the layer as normal shp file without problem. For the exported shp file, the attributes are correctly recognized in VIA (see second screenshot).

strange.. it works for me using the gpkg and directly opening it in QGIS. I see the geometries and the correctly read fields and I can color it accordingly

but yea I also have the same problem in via, that attributes are read as strings

Yes, I have tried it again in a newer QGIS version, and it displays the layer properly now.

So, I guess the issue is probably with VIA?
