Ok, I just actually re-read the LayerDefinitionFactory code and it seems your code is actually correct. Just a bad choice of variable names :|
Try this: echo the output of $factory->CreateLayerDefinition() and see if there are any %s in the xml. If there are, chances are you left out some parameter in one of the LayerDefinitionFactory calls, as it uses sprintf() string substitution. - Jackie uXuf wrote: > > Hi Jackie, > > I am getting a little confused by all this.
