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.

						choiceList.add( choice );
						if ( defaultValue != null
								&& defaultValue.equals( importValues[i] ) )
						{
							defaultValueRemoved = false;
						}
					}
					refreshValueTable( );
					if ( defaultValue != null && defaultValueRemoved )
					{
						changeDefaultValue( null );
					}
				}
			}
		} );
		changeDefault = new Button( buttonBar, SWT.TOGGLE );
		changeDefault.addSelectionListener( new SelectionAdapter( ) {
			public void widgetSelected( SelectionEvent e )
			{
				SelectionChoice choice = (SelectionChoice) ( (IStructuredSelection) valueTable.getSelection( ) ).getFirstElement( );
				if ( isDefaultChoice( choice ) )
				{
					changeDefaultValue( null );
				}
				else
				{
					changeDefaultValue( choice.getValue( ) );
				}
				refreshValueTable( );
