V-Leaflet with MarkerCluster

Hi, I’m testing with the V-Leaflet addon, and I was trying to include a MarkerCluster in a map, but I get an exception compiling the project:

Loading inherited module 'org.vaadin.addon.leaflet.markercluster.Widgetset' [ERROR] Line 7: Unexpected exception while processing element 'inherits' java.lang.NullPointerException at com.google.gwt.dev.cfg.ModuleDefLoader.nestedLoad(ModuleDefLoader.java:324) ... I’m using the V-Leaflet add-on version 0.5.6, and the V-Leaflet Markercluster extension version 0.4.5.

Anybody have a clue about what might be happening?

(I’ve already added the inherits in the widgetset description file)

Thanks in advance and regards,

Hi Martin,

Please make sure that you also have g-leaflet in your build path. Are you using Maven to build your project?


Matti, many thanks for your work and your answer.

That was indeed the cause of my problem: I’ve just added the g-leaflet jar to my project and now it’s working perfectly.

Really appreciate your time,
