[Geoserver-users] intervals with cql expression on quantity

[Jose Antonio]

*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.<init>(RasterLayerLegendHelper.java:96)*
* at

* 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,
José Antonio
