This is not about VLeaflet itself. As add-on has been migrated to Vaadin 8, there are some changes in inherited classes. In Vaadin 8 we do not have removeClickListeners (or removeXXXXListener) methods. Instead addClickListener returns reference to Registration object and you should remove the listener by calling registration.remove().
I’m using VLeaflet 2.0.1 add i’ve notice that the method “removeClickListener” has been dropped from LMap.
other alternatives or suggestions?
