Hi! I am using Dynamic Sybmbolyzer for my layer. In my layer i have a property "TTF_Symbol" which contains a font string like "ttf://<fontname>#<hexcode>" for each feature. I am using it like marks for my features.
The map render works fine, and draw my layer correctly. But when i trying to get legend for my layer using GetLegendGraphic request, i get following error message: <?xml version="1.0" encoding="UTF-8" standalone="no"?><!DOCTYPE ServiceExceptionReport SYSTEM "http://gis.dvo.ru:8080/geoserver/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd";> <ServiceExceptionReport version="1.1.1" > <ServiceException> java.lang.IllegalArgumentException: The specified mark ${TTF_Symbol} was not found! The specified mark ${TTF_Symbol} was not found! </ServiceException></ServiceExceptionReport> I have tried to avoid it by using LegendGraphic parameter in my SLD style. In the specification (05-077r4_OpenGIS_Symbology_Encoding_Implementation_Specification.pdf) is said: "The LegendGraphic element allows an optional explicit Graphic Symbolizer (described in Subclause 11.3) to be displayed in a legend for this rule." If i correctly understand it, in case when i use <LegendGraphic> parameter in my sld, geoserver shouldn't try to render icon for legend based on PointSymbolyzer rule, but just include in legend icon, which defined in <LegendGraphic>. I added <LegendGraphic> parameter in my SLD, but i still get error above. I have 2 questions: 1) Why map render works fine and legend render fails with that error? 2) Why Geoserver is ignoring <LegendGraphic> and still trying to render legend based on PointSymbolyzer rule? My sld file looks like: <?xml version="1.0" encoding="windows-1251"?> <StyledLayerDescriptor version="1.0.0" xsi:schemaLocation="http://www.opengis.net/sld StyledLayerDescriptor.xsd" xmlns="http://www.opengis.net/sld"; xmlns:ogc="http://www.opengis.net/ogc"; xmlns:xlink="http://www.w3.org/1999/xlink"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <NamedLayer> <Name>Поле ветра</Name> <UserStyle> <!-- 5' grid nodes.
