//client Controller

c.cloudService=[];
c.getHostLoc = function() {
var hostingLoc=c.hostloc.displayValue;
console. log("hostinglocation"+c.hostloc.displayValue);
if(hostingLoc==""){
c.cloudservprov='';
}
this.server.get({
action: "impHostingloc" ,
name: hostingLoc,
//listservice: selectedcloud
}).then (function(response) {
c.cloudservprovlist= response.data.cloudServiceProvidelist;
console.log("1891"+c.cloudservprovlist);
}


c.updateSelected =function (){
var selectedCloudService=c.cloudservprov;
console.log("response"+selectedCloudService);
if(selectedCloudService && selectedCloudService. length›0)(
this.server.get ({
action: "getServiceName",
 ids: selectedCloudService
}).then (function(response){
c.cloudService=response.data.name.join ',');
console.log("response"+c.cloudService);

}

//HTML
<sn-choice-list sn-model="c.cloudservprov" table="sn_capi_provider" display-field="name" value-fied='sys_id'
sn-items=c.cloudservprovList" multiple="true" on-change="c.updateSelected()"</sn-choice-list >

i am trying to get the values selected by the user , but in the console i am not getting all the values for eg:- first value is skipped first time and then it appears second time , so if i select 4 values only 3 are getting updated

var selectedCloudService=c.cloudservprov;
console.log("response"+selectedCloudService
