<p class=MsoNormal>I think this question may have been asked before but I’ve
looked online and can’t find it now. I’m using the following code
to get feature information to display in a popup, for some reason however, it
is only showing information from just one layer which is the first layer that
is called into the map? Does anyone know if this is a problem with GeoExt or
more likely something missing from code? Below is the snippet of code I am
using for generating featureinfo popup:<o:p></o:p></p>
