I am trying to trying to create Polyline map from the https://demo.cuba-platform.com/sampler/#!
and getting the error shown above

@cuba-platform any update on this issue?

Hi,

Pay attention that PolylineMapFrame extends AbstractFrame instead of AbstractWindow.

So, try to extend AbstractWindow and it should help.

I am trying to open map from other editor screen(journey) and I want to pass one parameter to map screen window from journey editor screen .

I am passing like this
ParamsMap.of(“journeyCode”, getItem().getJourneyCode())

How do i get this value in map screen window? inside init method
@Override
public void init(Map<String, Object> params) {
String journeyCode = “5A0mZMKCEH”;
}
currently i have hardcoded journey code as “5A0mZMKCEH”
