KML downloaded from Redline contains empty Placemark element

[zhanga]

If the stylization type of Redline widget is not set, or is set to Advanced Stylization, the KML file downloaded would contain some empty Placemark element.

MgKmlService::GetFeaturesKml doesn't handle Layer Definitions using Advanced Stylization does it?

If that's the case, the only real practical solution is to hide/disable the KML/KMZ export options if we're trying to export such a layer.

MgKmlService::GetFeaturesKml() uses StylizationEngine::StylizeVectorLayer() which calls method Stylize() for each style. In KmlRenderer::StartFeature, it will add "<Placemark>".
I think we can utilize the parameter initialPass, which is not used in KmlRenderer now. If initialPass is true, we add "<Placemark>", otherwise not.

Ok I stand corrected once again, I just drew some redlines with Advanced Stylization and exported it out to KML and got more points/polygons/lines than expected. Maybe it is the initialPass parameter you are talking about.
