[OpenLayers-Users] Correct format for cql_filter in WMSgetFeatiureInfo

[Asle Benoni]

I read in this discussion:
https://getsatisfaction.com/opengeo/topics/error_in_wmsgetfeatureinfo that "If
you use an array of URLs in your WMS layers, you do not need layerUrls."
and that is exactly what I am using, an array of layers. I can see it in
the WMS call to fetch features. Or am I uncorrect?
