> Geoff,
> this is a bug in GeoTools gt-main StaticGeometry:
> http://svn.osgeo.org/geotools/trunk/modules/library/main/src/main/java/org/geotools/filter/function/StaticGeometry.java
> In StaticGeometry at line 551 is the following:
> if (beg < 0 || end < 0 || beg >= s1.length() || end >= s1.length())
> return null;
> This is an off-by-one error as it is valid for end to be equal to the
> length of the string. The last clause should be "end > s1.length()".
> Thanks for the bug report. I will submit a patch to the module maintainer.
> Kind regards,

> Hi All,
> I think I may have found a bug with strSubstring() when used in <OCQL> tags.
> In nutshell, I'm unable to select the last character in a string. EG a
> mapping file containing:
> <AttributeMapping>
> <targetAttribute>gml:description</targetAttribute>
> <sourceExpression>
> <OCQL>strSubstring('ABCD',0,4)</OCQL>
> </sourceExpression>
> </AttributeMapping>
> Does not produce the gml:description element in the output (because the value
> coming back from strSubstring is null I assume). I would have expected the
> output here to have contained:
> <gml:description>ABCD</gml:description>
> Which is analogous to the Java code:
> "ABCD".substring(0,4);
> Which returns "ABCD"
> Whereas:
> <AttributeMapping>
> <targetAttribute>gml:description</targetAttribute>
> <sourceExpression>
> <OCQL>strSubstring('ABCD',0,3)</OCQL>
> </sourceExpression>
> </AttributeMapping>
> Produces an output containing:
> <gml:description>ABC</gml:description>
> As expected.
