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.

defaultValueChooser.select( 0 );
					}
					else if ( defaultValue.equals( "" ) )
					{
						defaultValueChooser.select( 1 );
					}
					else
					{
						defaultValueChooser.setText( defaultValue );
					}
				}
				else if ( defaultValue != null )
				{
					if ( ( defaultValue.equals( Boolean.toString( true ) ) || defaultValue.equals( Boolean.toString( false ) ) ) )
					{
						defaultValue = null;
					}
					else
					{
						defaultValueChooser.setText( defaultValue );
					}
				}
			}
			refreshValueTable( );
		}
		else
		{
			refreshDataSets( );
			if ( inputParameter.getDataSetName( ) != null )
			{
