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.

				else if ( DesignChoiceConstants.PARAM_CONTROL_TEXT_BOX.equals( type ) )
				{
					clearArea( valueArea );
					switchToText( );
				}
				valueArea.layout( );
				initValueArea( );
				lastControlType = type;
			}
		}
		updateCheckBoxArea( );
		updateMessageLine( );
		boolean radioEnable = false;
		if ( PARAM_CONTROL_COMBO.equals( getSelectedControlType( ) )
				|| PARAM_CONTROL_LIST.equals( getSelectedControlType( ) ) )
		{
			radioEnable = true;
		}
		if ( radioEnable != staticRadio.isEnabled( ) )
		{
			staticRadio.setEnabled( radioEnable );
			dynamicRadio.setEnabled( radioEnable );
		}
		initFormatField( );
