Combine Excel-like filters and drop-down lists with text search in the same table [message #1851636]

I implemented a tabular view based on NatTable. I use the ComboBoxFilterRowHeaderComposite for filtering the content and it works fine as long as I use the drop-down lists for each column. But for some columns, I prefer to use a text search field instead of the drop-down list. Unfortunately, that seems not to work.

I added a custom configuration that replaces ComboBoxFilterRowHeaderComposite 's default cell editor with a FilterRowTextCellEditor for the desired column index, but I have the following problems: (a) I still see the little triangle that is used for columns with drop-down lists instead of the filter icon. (b) If I try to edit the text field, I see the text entry "SELECT_ALL". (c) If I enter any text contained in the column, all column entries disappear. The filter does not work properly.

My confuguration code snippet:

    int descriptionColumnIndex = indexOfColumn( ColumnConstants.COLUMN_DESCRIPTION, columnHeaderDataProvider );
    if (descriptionColumnIndex != INDEX_NOT_FOUND ) {
      configRegistry.registerConfigAttribute(
          EditConfigAttributes.CELL_EDITOR,
          new FilterRowTextCellEditor(),
          DisplayMode.NORMAL,
          FilterRowDataLayer.FILTER_ROW_COLUMN_LABEL_PREFIX
              + descriptionColumnIndex);
    }

Am I doing something wrong or can ComboBoxFilterRowHeaderComposite not be used with FilterRowTextCellEditors?
Is there a simple way to debug the configuration, layers' behaviour, etc.?

The two filter mechanism can not be combined at the moment. At least not out of the box. The reason is that the filtering logic in the back is different whether you select explicit items from a dropdown or if you filter free text. Technically it would be possible, but that would be some work to get the two approaches work in combination.

For debugging we have the DebugMenuListener that opens a dialog with some information like labels etc. Not sure if this is what you are searching for.

Thank you for answering so quickly.

Do you mean, I would have to replace the ComboBoxFilterRowHeaderComposite and some other related classes with another implementation to make it work? I think, I'm not familiar enough with NatTable's internals to do that. Maybe that could be a feature for some of the next releases? :-)

Yes, I think, the DebugMenuListener is exactly what I was looking for.

Best regards.

Yes, the filter strategy, the composite etc. needs to be extended/modified to support a mixture of the two approaches.

Well, if you have the resources to sponsor such a feature, that would be possible.
