How to distinguish markers in on_click handlers?

[sradomski]

Hey there,

I have a bunch of markers (with potentially identical positions) in a MarkerCluster that will spiderfy at the appropriate zoom level. When a user clicks on a spiderfied marker, I want to display something specific for that marker within a WidgetControl. However, I am unable to identify the Marker that was clicked from within the on_click handler as only event, type and coordinates are passed, which are not unique.

Is there any way to know which actual marker was clicked?

Thank you
Stefan
