Hi, I managed to use GetFeatureInfo perfectly in my application after checking the example "Feature Info in Popup".
Every point that I click that has some information to be returned gets it returned. It's great. But the problem is, when I click in a place in the map that has no information, I mean, a point from my WMS layer that has no information about it in my source, it returns an empty popup. That behaviour also happens in the example. If you click in the white area, for example, it returns you an empty popup. The question I have is: how do I make for the popup to appear only when there's some information being returned ?? I'm using openlayers 2.8 Thanks for the attention guys Marcos -- "Saber o que é certo e não fazê-lo é a pior covardia."
