[Users] problem using 'legendURL'

[Bart van den Eijnden (OSGIS)]

Hi,

you need to set the legendURL not on the OpenLayers Layer object, but on
the GeoExt LayerRecord.

So look up the corresponding record in the layerstore (using e.g.
findByLayer), and use:

record.set("legendURL", "http://foo");

Best regards,
Bart
