[Users] How to create legend panel using OpenLayers.Layer.MapServer layer...

[Andreas Hocevar]

Hi,

make sure that your Ext JS build contains Ext.form.Label, or use a full
build. The build that most of the GeoExt exmaples use
(http://extjs.cachefly.net/builds/ext-cdn-771.js) does not contain it.
Look e.g. at
http://dev.geoext.org/trunk/geoext/examples/legendpanel.html, it uses a
full build.

Regards,
Andreas.
