[Geoserver-users] intervals with cql expression on quantity

Jose_Antonio · July 3, 2017, 4:18pm

Hi,

I was trying to generate a legend in geoserver with intervals and values passed with env function, but it seems not to work. There it is my syle:

<sld:ColorMap type=“intervals”>
<sld:ColorMapEntry color=“#d7191c” opacity=“0” quantity=“${env(‘nodata’,-1)}”/>
<sld:ColorMapEntry color=“#d7191c” opacity=“1.0” quantity=“${env(‘low’,0)}”/>

</sld:ColorMap>

The errors provided on the geoserver.log file are:

at org.geoserver.wms.legendgraphic.RasterLayerLegendHelper.parseRequest(RasterLayerLegendHelper.java:196)
at org.geoserver.wms.legendgraphic.RasterLayerLegendHelper.(RasterLayerLegendHelper.java:96)

at org.apache.wicket.protocol.http.WicketFilter.doGet(WicketFilter.java:484)
at org.apache.wicket.protocol.http.WicketServlet.doGet(WicketServlet.java:138)

is there any error in the style code or perhaps this is not supported yet? I ask here because I found something similiar in previous mails, but i haven’t found any solution yet.

Thanks in advance,

José Antonio

We really need the line above the error you include, that tells us what the actual error is

Hi,

I forgot to tell you that this error arises when you define de style in geoserver and push the button “preview legend”

Regards,
