[OpenLayers-Users] Popup Box Problem using multiple layers

[Phil Scadden]

Hmm, loading lots of layers by geoJSON is slow. Do you have a reason not 
to use WMS instead?

To your problem - in my app, the whole map configuration is read from a 
json config file so same code support many applications. In the config 
file, for each layer I am loading, I also store metadata on attributes 
and how I want them displayed. The popup creation combine that config 
information with attribute information.

This gives you a lot of control, but an alternative approach if you are 
using geoserver is freemarker templates and construct those popups 
serverside. This is a lot faster.
