[Geoserver-users] Nested Geometric Functions in SLD of GeoServer

[S Shadab]

I want to use nested geometric functions in SLD of GeoServer. For example I
want to set some offset for certain type of polygons in my data. Then output
of the offset geometric function needs to be given as input to another
geometric function isometric to give required extrusion. I tried with
following code. 

<Geometry>
<ogc:Function name="isometric">
  <ogc:Function name="offset">
    <ogc:PropertyName>the_geom</ogc:PropertyName>
    <ogc:Literal>0</ogc:Literal>
    <ogc:Literal>7</ogc:Literal>
    </ogc:Function>  
  <ogc:PropertyName>the_geom</ogc:PropertyName>
<ogc:Literal>7</ogc:Literal>
</ogc:Function>
</Geometry>

It gives no validation error but in layer preview, it is throwing the
following error:

<ServiceException>
      java.lang.RuntimeException: Unable to find function isometric
Unable to find function isometric
</ServiceException></ServiceExceptionReport>

Is it possible to use nested function? or I am doing something wrong here?

Thanks in Advance.

Syed Shadab
