[udig-devel] Running uDig 1.1-RC10a on Linux, I've attempted to display a layer from a SHP file with an SLD that filters symbols out to several different external graphics.,,The SLD validates, and the symbols do indeed display, filtered as they should. However, any re-rendering of the map (zoom in or out, for instance) generates about 10 instances of "An error has occurred. See error log for details." before it finally displays the map correctly., , I'm attaching a text file with snippets from the SLD and from the log. (We'll see if that makes it through.) Any direction would be appreciated.,,I'd like to echo Peter Schweitzer's comments: uDig is very usable and a place to post the "How do I do this?" questions I haven't seen answered yet would be helpful -- a place where we wouldn't be bothering the developers, that is.,,Ron Bentley

I'd like to echo the sentiments that a place to post the "How do I do this?" questions I haven't seen answered yet would be helpful -- a place where we wouldn't be bothering the developers, that is.
