Disable a specific button in a ButtonCell

Hey,

we tried it in different ways and we couldnt find a solution for our problem.

We create a Table with games, so a lobby and there are all our games with informations and a "join"-button.

If the game is full or the user is already in the game, we want to disable the button.

// Join Column for the Game (Join a Game)

ButtonCell joinGame = new ButtonCell();

Column<Game,String> gameOption = new Column<Game,String>(joinGame) {

public String getValue(Game game) {

if(game instanceof RunningGame){

return "Game is running";

}else if(!game.hasFreeSlot()){

return "Game is full";

}else if(game.containsUser(Presenter.currentUser.getName())){

return "You are already in this game";

}

return "Go in";

}

};

 Like this we get after every redraw the right caption for the buttons. We used a lot of time to write a new class for deactivatable ButtonCells, but it didnt work.

Can anyone please help us?

Best Regards

Björn
