<div><div dir="ltr"><div><div>Hey list,</div><div><br></div><div>I have a question on the OpenLayers Cluster strategy and displaying attributes:</div><div><br></div><div>The situation: I have a map loading quite a number of points from a dynamically generated GML. Currently, I am not using a cluster strategy, but the handling gets more and more difficult. When I hover the points, I send the <a href="http://feature.attributes.Name" target="_blank">feature.attributes.Name</a> content (Content of the Name attribute in the GML) to a function for displaying a tooltip. No problem until I want to cluster the features. I understand, that after clustering, the attribute "Name" doesn't exist anymore. What I want to do now is, when it is a cluster of more than one feature, I want to send "Cluster of feature.attributes.count" to my tooltip function, which is also not a problem, but, if there is only one feature in the cluster, I want to send the <a href="http://feature.attributes.Name" target="_blank">feature.attributes.Name</a> of that feature to the tooltip function. I hope you understand what I am trying to achieve. </div>
