Hi list,
I wonder if anyone else has seen something like this.
I have a PostGIS table defined basically as
CREATE TABLE vdline
(
ogc_fid serial NOT NULL,
hast_gener character varying,
kode_hast0 character varying,
hast_lokal double precision,
hast_gaeld double precision,
hast_anbef double precision,
hast_var_h character varying,
geometri geometry(MultiLineString),
CONSTRAINT vdline_pkey PRIMARY KEY (ogc_fid)
)
WITH (
OIDS=FALSE
);
I publish it through GeoServer 2.9.1, using a style looking basically like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<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";

<NamedLayer>

<VendorOption name="group">true</VendorOption>
</TextSymbolizer>
</Rule>
</FeatureTypeStyle>
</UserStyle>
</NamedLayer>
</StyledLayerDescriptor>
The complete SLD contains multiple <FeatureTypeStyle>s for various values of
<PropertyName>hast_lokal</PropertyName>.
If I make a GetLegendGraphic-request like
http://hostname/workspace/wms?service=WMS&version=1.1.0&request=GetLegendGraphic&layer=vdline&format=image/png
I get the error:
<?xml version="1.0" encoding="UTF-8" standalone="no"?><!DOCTYPE
ServiceExceptionReport SYSTEM
"http://gs.demo.geoteamwork.com:80/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd";>
<ServiceExceptionReport version="1.1.1" > <ServiceException>
java.lang.IllegalArgumentException: Filter Function problem for function
round argument #0 - expected type float
Filter Function problem for function round argument #0 - expected type float
</ServiceException></ServiceExceptionReport>
If I modify the SLD, specifically the <Label>, removing the <ogc:Function
name="round">, so that it becomes
<Label>
<ogc:PropertyName>hast_gaeld</ogc:PropertyName>
</Label>
I get a nice legend. Is that a bug?
