I am having a similar issue as to what Dominik mentions here: Problems with TOC or map
I do not have the Editor or Measurement dijit added in. Right now, I am missing several layers in the TOC. When using the developer tools in Firefox, I get an error that the graphic can not be drawn. They happen to all be point layers, but other point layers are pulling in without throwing that error.
Also, when I zoom on the map, the map is not updating unless I pan. When I pan, the polygons are not drawing. If I do not pan, the resolution never gets any better.
Thanks in advance!
