Hi Denis,<br/><br/>thanks for your answer.<br/>addBuilding is a custom function that creates a vector on the vector layer with a special icon.<br/>I already use vectors instead of markers, apologies for my unclear description. I do have a vector layer and place different vectors of OL.Features.Vector on it. But I can't get the clustering work so far. The only difference between your code and mine is that you add 'autoactivate: true' to your Cluster constructor, I don't know if this is mandatory for the clustering to work, I will test it on Monday. Any other comments on that?<br/><br/>I really appreciate your fast and competent answer!<br/><br/>Regards<br/>Stefan<br/><br/><br/><br/><blockquote style="border-left: 2px solid blue; margin-left: 5px; padding-left:5px; padding-top:5px;"><hr/><b>Von:</b> "dr [via OSGeo.org]" <<a href="/user/SendEmail.jtp?type=node&node=6779018&i=0" target="_top" rel="nofollow" link="external">[hidden email]</a>><br/><b>Gesendet:</b> Sep 10, 2011 2:16:52 PM<br/><b>An:</b> chemiker <<a href="/user/SendEmail.jtp?type=node&node=6779018&i=1" target="_top" rel="nofollow" link="external">[hidden email]</a>><br/><b>Betreff:</b> Re: Can't get clustering work<br/><br/>Hi!<br/><br/>What is addBuilding function?<br/><br/>I'm not sure about cluster strategy may be used with markers. I'm prefer to use features, because markers are deprecated:<br/><br/><pre><html><body>
