Bug 177439 Need an easy way to determine default value for a dynamic parameter
Currently, I have to bring up the data set editor, preview the results in the data set and make a mental note of the value to use for a report parameter that depends on a data set. It would be nice to have a drop down on the default value field, such as <Select value> which when selected queries the data set and presents me with a list to select from.

		public void dispose( )

		public boolean isLabelProperty( Object element, String property )
		{
			return false;
		}
		public void removeListener( ILabelProviderListener listener )
		{
		}
	};
	private ICellModifier cellModifier = new ICellModifier( ) {
		public boolean canModify( Object element, String property )
		{
			if ( element != selectedParameter )
			{
				return false;
			}
			if ( property.equals( COLUMN_NAME ) )
			{
				return true;
			}
			if ( COLUMN_DATA_SET.equals( property ) )
			{
				if ( isSingle( ) && getFirstParameter( ) != element )
				{
					return false;
