How to uncheck CheckBoxCellEditor? [message #1018267]

Hi,

my out-of-the-box CheckBoxCellEditor refuses to become unchecked. How can that be achieved? I can check it but it is not possible to uncheck once it is checked.

Hi Joachim,

Have a look at the EditableGridExample. This should work. If yours is not, you'll need to provide some more information about your setup - ideally a test program that demonstrates the issue.

Thanks,
Edwin

Thanks for the quick answer. Well, I used the EditableGridExample as my guide.

There is a CheckBoxPainter, a Validator, a DefaultBooleanConverter and the CheckBoxCellEditor configured for boolean values. What is different from the example is that I have extended the CheckBoxPainter like this:

@Override
protected Boolean convertDataType(ILayerCell cell, IConfigRegistry configRegistry) {
	boolean result = false;
	Object o = cell.getDataValue();
	if (null != o && o instanceof MyObj) {
		MyObj o = (MyObj) o;
		result = Boolean.parseBoolean(o.getValue());
	}
	return result;
//				return super.convertDataType(cell, configRegistry);
}

Otherwise I run into the following Exception, which lets me think that my configuration is not 100% accepted by the nattable (looks like the converter is not being set correctly). All other types are OK with their painters, converters, editors.

I don't think you need the DefaultBooleanConverter when using CheckboxPainter and CheckboxCellEditor. These two will complain if the underlying value is NOT a boolean, otherwise you don't need to care.

These are the labels and converter for the cell:

[LABEL_COLUMN_VALUE, LABEL_VALUE:HALF-DUPLEX, HALF-DUPLEX, LABEL_PAINTER_BOOLEAN, LABEL_CONVERTER_BOOLEAN, LABEL_EDITOR_BOOLEAN, selectionAnchor, BODY]
org.eclipse.nebula.widgets.nattable.data.convert.DefaultBooleanDisplayConverter@3e4a9a7d

The click on the checkbox is honored but for some reason it does not change the value of it. The validator gets a TRUE for validation, which should be a FALSE.
