Bug 144077 Throw exception when generate SVG chart which has inteactive
There is a program mistake in "org.eclipse.birt.chart.device.svg" project. In "SVGInteractiveRenderer" class, "findCategorySeries" method, "getSeries( ).get( 1 )" should be changed to "getSeries( ).get( 0 )". It will throw exception when generate SVG chart which has inteactive. And i find this in 2.1RC3a.

Element outerGroup = svg_g2d.createElement( "g" ); 
					svg_g2d.pushParent( outerGroup );
					Element primGroup = svg_g2d.createElement( "g" ); 
					outerGroup.appendChild( primGroup );
					svg_g2d.pushParent( primGroup );
					primGroup.setAttribute( "id", groupIdentifier + "_" + id ); 
					primGroup.setAttribute( "style", "visibility:visible;" ); 
					outerGroup.setAttribute( "id", groupIdentifier + "_" + id + "_g" ); 
					outerGroup.setAttribute( "style", "visibility:visible;" );

					String id = Integer.toString( pre.hashCode( ) );
					List components = (List) componentPrimitives.get( seDT );
					if ( components == null )
					{
						components = new ArrayList( );
						componentPrimitives.put( seDT, components );
					}
					
					
					String idTemp = id;
					int counter = 1;
					while ( components.contains( idTemp ) )
					{
						idTemp = id + "@" + counter; 
						counter++;
