Re: Auto zoom and center map problem

Thanks for fast reply.

I have added a control that skips entries with lat/lon (0,0) when
filling bounds array.Now the zoom level is set to 4 in all cases in
place of 2 as how it was before.And also if you click on last cluster
(Toelevering en dienstverlening), the marker is located on iceland but
the zoom level and position of map is not set automatically to see the
marker on iceland properly..only a small part of it is visible..

I can re-create the markers when any of them are matching with the
selected cluster but i dont have a cluer before re-create the marker
how destroy the existing one instead of hiding it as how i am doing
currently ?
