+	* src/main/java/de/intevation/gnv/geobackend/sde/datasources/Row.java (getPosValue):
+	  Added support for MultiLineString-Geometries. The Points do not belong to one 
+	  Geometryelement. We have to lookup if the Geometry is Multiparted.
+	  If it is we have to split the Points into several LineStrings which belongs 
+	  to one MultiLineString.

 	* src/main/java/de/intevation/gnv/geobackend/sde/datasources/ArcSDEResultSetMetaData.java (getColumnClassName): 
 	  Added more ClassName identificaton for the different datatypes of the ArcSDE.
 	  Now it is possible to distinguish between Integer, Long, String, Date,
