Cell Editors not showing up [message #1823353]

Hello,

I created a simple example, which uses editors (checkbox) and painters(also checkbox)

all is working fine.
when i try to place this into my (way more complex) version of nattable in my application the painter gets shown, but the editor never shows up.

what can cause this?
I tried to debug this via EditController.editCell, but this seems to be never called.

i register a boolean editor like this:

	protected static void registerBooleanEditor(IConfigRegistry configRegistry, FieldInfo fi) {
		String COLUMN_LABEL = ColumnLabelAccumulator.COLUMN_LABEL_PREFIX + fi.getIndex();
		configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITOR, new CheckBoxCellEditor(),
				DisplayMode.EDIT, COLUMN_LABEL);

configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, new CheckBoxPainter(),
				DisplayMode.NORMAL, COLUMN_LABEL);

configRegistry.registerConfigAttribute(CellConfigAttributes.DISPLAY_CONVERTER, new BooleanDisplayConverter(),
				DisplayMode.NORMAL, COLUMN_LABEL);

 }
	}

for testing i set a custom style which marks the columns with a red background. so i can be sure the correct labels are used.

result: red background with checkbox (if i do not register the CELL_PAINTER its text (true/false), but the editor does never show up (cell not activated?)

whats the best way to debug this?

EDIT:
i configured an EditingRule, which returns always true - for testing -
when i create the GridLayer with useDefaultConfiguration=true editors get shown up for unconfigured fields, but the CheckBox Editor is still not coming (and also not a text editor in this column)

There is no active CheckBoxCellEditor. It immediatelly switches the values and closes, and then the checkbox for the updated boolean value is shown.

If it is not working, probably your configuration is overriden by something. Hard to tell. But it sounds like some configuration for that column is incorrect, as for other columns the editor activation seems to work.

You need the DefaultEditBindings in place as described here: https://www.eclipse.org/nattable/documentation.php?page=editing

You could debug via the EditCellCommandHandler or the EditSelectionCommandHandler, dependent on how you want to activate the editor.
