[OpenLayers-Users] Search for features, show popup when select

[Marc Jansen]

Hi Herman,

I'd try this at the place where you have your comment in the 
rowclick-callback-function:

var popup = new OpenLayers.Popup.FramedCloud(
  "chicken", 
  bounds.getCenterLonLat(),
  null,
  "<div style='font-size:.8em'>Feature: " + feature.id +"<br />Area: " + feature.geometry.getArea()+"</div>",
  null,
  true
);
feature.popup = popup;
map.addPopup(popup);


untested, original code from 
http://www.openlayers.org/dev/examples/select-feature-openpopup.html

Regards,
Marc
