Hi,
I am trying to cut a substring from my data for labeling polygons, i'm using the strSubstring function,
but Geoserver doesn't render any label.
According to documents (http://docs.geoserver.org/stable/en/user/filter/function_reference.html#string-functions),
strSubstring syntax is:
strSubstring(string, integer, integer)
Here is a snippet of my sld:
<Label>
<ogc:Function name="strSubstring">
<ogc:PropertyName>NOMENC_MZN</ogc:PropertyName>
<ogc:Literal>1</ogc:Literal>
<ogc:Literal>10</ogc:Literal>
</ogc:Function>
</Label>
Geoserver's log shows:
2012-11-06 13:47:51,554 ERROR [renderer.label] - Error adding label to the label cache
java.lang.IllegalArgumentException: Filter Function problem for function strSubstring argument #1 - expected type int
I found a similar issue, and my solution was to explicitly convert
the literal numbers to ints, like this:
<ogc:Function
name="parseInt">
<ogc:Literal>0</ogc:Literal>
</ogc:Function>
Thanks Ákos, that's works!!!!
