problem with handle action

I find a problem with the method handleAction:

public void handleAction(Action action, Object sender, Object target) {
LOGGER.info("anskjanzkjsnzkajnsk",action+" "+sender+" "+target);

if (ACTION_MARK == action) {
markedRows.add(target);
table.refreshRowCache();
LOGGER.info("ACTION_MARK" +ACTION_MARK);
} else if (ACTION_UNMARK == action) {
markedRows.remove(target);
table.refreshRowCache();
LOGGER.info("ACTION_UNMARK" +ACTION_UNMARK);
} else if (ACTION_LOG == action) {
Item item = table.getItem(target);
addComponent(new Label("Saved: "
+ target
+ ", "
+ item.getItemProperty(
ExampleUtil.iso3166_PROPERTY_NAME)
.getValue()));
}

}

});

this method can't handles any action..

Have you attached the action handler to a window or something similar? Does it ever get into the method?

the probleme is never get into the method.
the handler action is attached to a table.
