[OpenLayers-Users] Zoom to a particular feature

[Luís de Sousa]

Hello everyone, this is really comical.

This code doesn't work:

map.addLayers([selLayer]);

var bds = OpenLayers.Layer.Vector.prototype.getDataExtent.apply(selLayer);
map.zoomToExtent(bds);

But this does:

map.addLayers([selLayer]);

setTimeout("Zoom()", 150);

function Zoom() {
      var bds = OpenLayers.Layer.Vector.prototype.getDataExtent.apply(selLayer);
      map.zoomToExtent(bds);
}

Funniest thing of all is that for IE, the timeout has be hiked to 300.

So, any elegant way of doing this?

Thank you,

Luís
