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 widgetSelected( SelectionEvent e )
			{
				refreshValueTable( );
				updateButtons( );
			}
		} );
	}
	private void createDynamicParamsPart( Composite parent )
	{
		Composite comp = new Composite( parent, SWT.NULL );
		comp.setLayout( UIUtil.createGridLayoutWithoutMargin( ) );
		comp.setLayoutData( new GridData( GridData.FILL_HORIZONTAL ) );
		Label label = new Label( comp, SWT.NULL );
		label.setText( LABEL_PARAMETERS );
		table = new Table( comp, SWT.FULL_SELECTION
				| SWT.HIDE_SELECTION
				| SWT.BORDER );
		GridData data = new GridData( GridData.FILL_HORIZONTAL );
		data.heightHint = 100;
		table.setLinesVisible( true );
		table.setHeaderVisible( true );
		table.addKeyListener( new KeyAdapter( ) {
			public void keyReleased( KeyEvent e )
			{
				
				if ( e.keyCode == SWT.DEL )
				{
					deleteRow( );
				}
			}
