Bug 207564 Column sorting based on data type
Only string sorting happens when a column is selected in preview result page of DataSet Editor irrespective of type of data shown in that column. I'd like to be able to sort the data based on its datatype when a column is selected.

{
		 
		 
		
		
		
		
		String classPath = System.getProperty( "workspace.projectclasspath" );
		if ( classPath == null || classPath.length( ) == 0  )
			return parent;
		
		String[] classPathArray = classPath.split( File.pathSeparator, -1 );
		int count = classPathArray.length; 
		URL[] urls = new URL[count];
		for ( int i = 0; i < count; i++ )
		{
			File file = new File( classPathArray[i] );
			try
			{
				urls[i] = file.toURL( );
			} catch ( MalformedURLException e )
			{
				urls[i] = null;
			}
		}
		return new URLClassLoader( urls, parent);
	}
