Database Values Plugin and Two Dimensional Filter Statistics

[Sentinel1 Integration Team Sentinel1]

When using Database Values Plugin custom fields in the Two Dimensional Filter Statistics portlet, the link for "None" doesn't take to the correct query but to the las one used by the user.

Please see https://jira.atlassian.com/browse/JRA-13024

I just tested it and I can confirm it is an issue. Support for this is done through implementing the CustomFieldStattable interface. I have it currently like this:

public StatisticsMapper getStatisticsMapper(CustomField customField)
	{
		return new AbstractCustomFieldStatisticsMapper(customField)
		{
			@Override
			protected String getSearchValue(Object o)
			{
				if( o == null )
				{
					return null;
				}
				else
				{
					return ((IdAndString) o).getId();
				}
			}

			public Object getValueFromLuceneField(String id)
			{
				// Convert the primary key into something nice
				if( id != null )
				{
					String text = DatabaseValuesViewHelper.getViewHelper(customField).getTextForStatistics(id, getDescriptor().getI18nBean());
					return new IdAndString(id, text);
				}
				else
				{
					return null;
				}
			}

			@Override
			public Comparator getComparator()
			{
				return new Comparator()
				{
					public int compare(Object o1, Object o2)
					{
						if (o1 == null && o2 == null)
						{
							return 0;
						}
						else if (o1 == null)
						{
							return 1;
						}
						else if (o2 == null)
						{
							return -1;
						}
						return ((IdAndString) o1).getText().compareTo(((IdAndString) o2).getText());

					}
				};
			}
		};
	}

I don't know what I do wrong to support the 'none' hyperlink case?
