[Gvsig_english] SLD grammar syntax

[Antonio Falciano]

Hi all,
there aren't dark secrets behind... It seems a bug: the parser of
the Expression filter doesn't accept floating decimal, in fact:

[Field]>= 5   ...works like a charm

[Field]>= 0.5 ...returns a NumberFormatException

 From the gvsig.log of gvSIG 1.12 devel (build 1406):

For input string: "[Field]" java.lang.NumberFormatException: For input 
string: "[Field]" sun.misc.FloatingDecimal.readJavaFormatString(Unknown 
Source) java.lang.Double.valueOf(Unknown Source)     java.lang.Double. 
(Unknown Source) 
org.gvsig.symbology.fmap.rendering.filter.operations.GreaterThanOrEqualsOperator.evaluate(GreaterThanOrEqualsOperator.java:74) 

org.gvsig.symbology.fmap.rendering.VectorFilterExpressionLegend.getSymbolByFeature(VectorFilterExpressionLegend.java:178) 
     com.iver.cit.gvsig.fmap.layers.FLyrVect._draw(FLyrVect.java:448) 
com.iver.cit.gvsig.fmap.layers.FLyrVect.draw(FLyrVect.java:627) 
com.iver.cit.gvsig.fmap.DefaultMapContextDrawer.draw(DefaultMapContextDrawer.java:209) 

com.iver.cit.gvsig.fmap.DefaultMapContextDrawer.draw(DefaultMapContextDrawer.java:175) 
     com.iver.cit.gvsig.fmap.MapContext.draw(MapContext.java:1088) 
com.iver.cit.gvsig.fmap.MapControl$PaintingRequest.paint(MapControl.java:1043) 

com.iver.cit.gvsig.fmap.MapControl$Drawer2$Worker.run(MapControl.java:1234) 
     java.lang.Thread.run(Unknown Source)

Cheers,
Antonio
