How to correctly use ButtonCellPainter? [message #1137469]

I followed the Rendereing_a_cell_as_a_button example and did the following:

Added a button cell painter to each cell with a specific label
Added a ButtonClickConfiguration similar to the one in the example
Added a click listener to the painter

But the button is neither shown as pressed nor is the click listener even called when clicking the button. What am I missing? When adding a LayerListener to my table which simply logs all received events, it only receives cell selection events.

EDIT: I did some more research:
When adding the configuration to the selection or the data layer of the table body, it is called, but the layer stack only contains the layer BODY, even if I attach the label accumulator right there. The label accumulator works correctly as the labels are used as a base for rendering, and the buttons are rendered correctly. Plus, the button does not appear pressed when I click it.

How did you create the ButtonCellPainter? Did you specify two different painter or one interiour painter?
Did you ensure to add your ButtonClickConfiguration BEFORE calling natTable.configure()?

I haven't implemented the ButtonCellPainter nor have I ever used it before. Looking at the implementation scares me as it uses background threads to update the visualization. But I really don't know what happens.

I did it this way:

final TextPainter flatCellPainter = new TextPainter();
final ButtonCellPainter bcp = new ButtonCellPainter(new BeveledBorderDecorator(flatCellPainter), new BeveledBorderDecorator(flatCellPainter, false));
config.registerConfigAttribute(CELL_PAINTER, bcp, NORMAL, MY_BUTTON_LABEL);
bcp.addClickListener(new IMouseAction() {

    @Override
    public void run(final NatTable natTable, final MouseEvent event) {
        // do stuff
    }
});

config is a ConfigRegistry.

Are you doing this in a configuration? And when are you adding the configuration?

Sorry for not answering this thread for a long time, but it turned out that I did not need buttons in that table. I came up with a combo box solution which just works fine. I wanted the button to be a "Delete" button in the last column of every row, which now opens a combo box where I can select "Yes" or "no". So I got a nice user confirmation without having to open a dialog box.
