Hello ,

I am facing two issues with filtering below i am giving a brief description for it kindly help me out to resolve it:

1)We have 3 columns with only possible data being + and - .I have added a combo filter to filter + and - .Filter works fine when for below combinations:
a) +,+ and -
b) -,- and +

where as when i apply the below combinations it doesn't work:
c) -,+ and +
d) +,- and +
e) -,+ and -
f) +,- and -
(In other words i feel there is a issue with already applied filter data value)

Filter Configurations added is given below :
ICellEditor comboBoxCellEditor = new ComboBoxCellEditor(
Arrays.asList(PLUSMINUS.PLUS.getOperator(), PLUSMINUS.MINUS.getOperator()));
configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITOR, comboBoxCellEditor, DisplayMode.NORMAL,
FilterRowDataLayer.FILTER_ROW_COLUMN_LABEL_PREFIX + 19);
configRegistry.registerConfigAttribute(FilterRowConfigAttributes.TEXT_MATCHING_MODE, TextMatchingMode.EXACT,
DisplayMode.NORMAL, FilterRowDataLayer.FILTER_ROW_COLUMN_LABEL_PREFIX + 19);

comboBoxCellEditor = new ComboBoxCellEditor(Arrays.asList("+", "-"));
configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITOR, comboBoxCellEditor, DisplayMode.NORMAL,
FilterRowDataLayer.FILTER_ROW_COLUMN_LABEL_PREFIX + 20);

ICellEditor comboBoxCellEditor1 = new ComboBoxCellEditor(
Arrays.asList(PLUSMINUS1.PLUS1.getPm1(), PLUSMINUS1.MINUS1.getPm1()));
configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITOR, comboBoxCellEditor1,
DisplayMode.NORMAL, FilterRowDataLayer.FILTER_ROW_COLUMN_LABEL_PREFIX + 21);
configRegistry.registerConfigAttribute(FilterRowConfigAttributes.TEXT_MATCHING_MODE, TextMatchingMode.EXACT,
DisplayMode.NORMAL, FilterRowDataLayer.FILTER_ROW_COLUMN_LABEL_PREFIX + 21);

2)I want to add custom filtering strategy along with the standard filtering support which comes from DefaultGlazedListsFilterStrategy how can that be achieved ?Firstly I want to understand is it possible if yes kindly clarify.

1) I suppose you run into a bug in NatTable 1.5. There a mechanism was contributed to increase the filter performance for multiple filter criterias, but for equal values the caching is not working correctly. We fixed that in the development branch which we hopefully soon will release as 1.6.
2) There is no concept for adding a custom filter strategy. You can only implement your own, probably extending the DefaultGlazedListsFilterStrategy and use that. That is of course possible and used by several users.

Hello Dirk,

I am trying to achieve custom filtering by following code:

CustomMatcherEditor:
EmptyMatcherEditor<SmdData> matcherEditors = new EmptyMatcherEditor<>(accessor, 31);

CompositeMatcherEditor<SmdData> compositeMatcherEditor = new CompositeMatcherEditor<SmdData>();
compositeMatcherEditor.getMatcherEditors().add(matcherEditors);

FilterRowHeaderComposite filterRowHeaderLayer = new FilterRowHeaderComposite(
new DefaultGlazedListsFilterStrategy(filterList, compositeMatcherEditor, accessor, configRegistry),
columnGroupHeaderLayer, columnHeaderDataLayer.getDataProvider(), configRegistry);

I have put some some println statements in the EmptyMatcherEditor which gives me a indication that configuration is quiet OK but the rows are not getting filtered accordingly .Kindly help me out and let me know if i am missing anything.
Thanks in advance.
