again, thanks a lot for your response, Andreas.<br>Finally I used the
vector layer's events (featuresadded) with something like:</font></font></p>
<pre><font face="Arial, sans-serif"><font size="3">var vecLayer = new OpenLayers.Layer.Vector("WFS", {</font></font>
<font face="Arial, sans-serif"><font size="3">eventListeners: {</font></font>
<font face="Arial, sans-serif"><font size="3">featuresadded: function() {</font></font>
<font face="Arial, sans-serif"><font size="3">var extent = vecLayer.getDataExtent()</font></font>
<font face="Arial, sans-serif"><font size="3">mapPanelWMS.map.zoomToExtent(extent);</font></font>
<font face="Arial, sans-serif"><font size="3">mapPanelWFS.map.zoomToExtent(extent);</font></font>

<font face="Arial, sans-serif"><font size="3">});</font></font>

Hi,<br>
<br>
loading the features is asynchronous. If you want to access the features, you have to wait until they are loaded. The best way to do so is register for the store's load event.<br>

Andreas.<br>
