[OpenLayers-Users] Draw Box From Selected Features

[Alexandre Dube]

Hi Richard,

   Using Firebug, try to watch VectoLayer.features to see if the feature 
gets correctly pushed.  I think it should since your code looks okay at 
first sight.  If it is, then it could simply be a styling issue.  Try 
removing the last argument when creating the feature to let the default 
style be used.

   If that doesn't help, try to put a break point in the 'addFeatures' 
method of OpenLayers/Feature/Vector.js to see what's going on.

HTH,

Alexandre
