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.addModifyListener( new ModifyListener( ) {
			public void modifyText( ModifyEvent e )
			{
				String value = defaultValueChooser.getText( );
				if ( value.equals( CHOICE_NULL_VALUE )
						|| value.equals( CHOICE_BLANK_VALUE ) )
					return;
				changeDefaultValue( UIUtil.convertToModelString( value, false ) );
				if ( isStatic( ) )
				{
					refreshValueTable( );
				}
			}
		} );
