i would like to make changes to the symbology of my feature layer (feature layer 1). Hence I tried to use and adopt one of your samples from the resource center: feature layer --> based on map service layer, to apply this to my own feature layer. However, an error occurs with the "featurelayer1_graphicAddHandler" and I don't know why. error message: original in german: Error 1180: call to a possibly undefined method "featurelayer1_graphicAddHandler"
