Hi GS users,

I just noticed that there is an error or possibly a bug in sld:pointSymbolizer. I used the following sld file:
""
<sld:FeatureTypeStyle>
        <sld:Name>name</sld:Name>
        <sld:Rule>
          <sld:Name> Low XX </sld:Name>
          <sld:Title>Low XX</sld:Title>

            <ogc:PropertyIsLessThan>
              <ogc:PropertyName>var1</ogc:PropertyName>
              <ogc:Literal>10</ogc:Literal>
            </ogc:PropertyIsLessThan>
          </ogc:Filter>
          <sld:PointSymbolizer>
            <sld:Graphic>

I want all the points with var1>=10 to be rendered using the High XX rule. But what I noticed is that all the points where the first digit of var1 is greater than 1 are grouped and colored as High XX. For example a point with var1=5 is rendered as High XX. I also checked the geoext styler and the result is the same. So I think this should be a bug.
Has anybody else encountered this problem?

Thanks,
Manouchehr

Sounds like a data type problem, the behavior you see is compatible
with text based comparison
instead of numeric comparison.
Is the data stored in a database? If so, is var1 a text column?

Cheers

Dear Andrea,
Thanks for the hint. Yes it was a data type problem.

Best,
