Hello,
i try this
this.listeners["changeValue"] =
this.widgets["datum"].addListener("changeValue", function(e) {
this.loadTimelist();
},this);
this.listeners["SHOPID"] =
this.widgets["SHOPID"].addListener("changeSelection", function(e) {
this.loadTimelist();
},this);
and later this
if(this.listeners["datum_changeValue"]) {
this.widgets["datum"].removeListenerById(this.listeners["datum_changeValue"]);
}
if(this.listeners["SHOPID_changeSelection"]) {
this.widgets["SHOPID"].removeListenerById(this.listeners["SHOPID_changeSelection"]);
}
this.listeners = [];
but the events not destroyed
