Load Layers from Config file

Question asked by LuciH on Sep 11, 2012
Latest reply on Sep 18, 2012 by LuciH
Is anyone familiar with loading layers from a config file?  I am trying to do it and I get various results depending upon the method I try.  The method quoted gives me duplicate entries of each layer added.  I have created the array called layrnames, but cannot determine proper function to use to load all the layers names I have pushed into the array.  Any help would be greatly appreciated :)

Thanks,  Luci
