webix.once is not passing arguments.

[Andrey G.]

current implementation:

webix.once=function(method){
    var flag = true;
    return function(){
        if (flag){
            flag = false;
            method.apply(this, arguments);
        }
    };
};

in that case arguments will be always empty array. looks like you wanted this:

webix.once=function(method){
    var flag = true;
        var args = arguments;
    return function(){
        if (flag){
            flag = false;
            method.apply(this, args);
        }
    };
};
