If we use the context menu of tree or table, we should add a ActionHandler to the tree or table,for example :

table.addActionHandler(new Action.Handler() {
            public Action[] getActions(Object target, Object sender) {
                if (markedRows.contains(target)) {
                    return ACTIONS_MARKED;
                } else {
                    return ACTIONS_UNMARKED;

the limits is the return type of the method, it return a single-dimensional array. it means we can't have sub menu of each menu.:angry:

anybody has any solution?
