Returning invalidMessage Before Validation Completes in Custom Duration Validator

Hello everyone,

I'm working on a custom duration validator in Creatio, but I'm running into an issue where the function returns invalidMessage before the validation logic completes.

Here’s a simplified version of my function:

durationValidator: function(){
                var invalidMessage="";
                var name=this.get("UsrNameLookup").value ?? null;
                var currentDuration=this.get("UsrDurationMinute");
                if(!name){
                    return;
                }
                var esqDuration = this.Ext.create("Terrasoft.EntitySchemaQuery", {
               rootSchemaName: "UsrPerformances"
           });
                esqDuration.addColumn("UsrDurationMinute");
                // var groupFilters = this.Ext.create("Terrasoft.FilterGroup");
                
                var totalDuration = 0;
                if(this.isAddMode()){
                    var nameFilter = this.Terrasoft.createColumnFilterWithParameter(this.Terrasoft.ComparisonType.EQUAL, "UsrNameLookup", name);
                // groupFilters.addItem(filterId);
                esqDuration.filters.add("esqFirstFilter",nameFilter);
                    esqDuration.getEntityCollection(function(result) {
                   if (!result.success) {
                       this.showInformationDialog("Request error");
                       return;
                   } else {
                       result.collection.each(function(item) {
                               totalDuration += item.get("UsrDurationMinute");
                           }
                       );
 
                   }
                   totalDuration += currentDuration;
                        console.log(totalDuration);
                   this.Terrasoft.SysSettings.querySysSettingsItem("UsrMaximumDuration", function(maxDuration) {
                       // console.log("td"+totalDuration);
                       if (totalDuration > maxDuration) {
                            this.set("Numbervalue", false);
                           this.showInformationDialog("No more than " + maxDuration + " total performances duration is allowed.");
                            invalidMessage= "No more than " + maxDuration + " total performances duration is allowed.";
                            return{
                                invalidMessage: invalidMessage
                            };
                       } 
                        else {
                            this.set("Numbervalue", true);
                            invalidMessage="";
                            return{
                                invalidMessage: invalidMessage
                            };
                       }
                   }, this);
 
               }, this);
                }else{
                    console.log("else");
                    var nameFilter = this.Terrasoft.createColumnFilterWithParameter(this.Terrasoft.ComparisonType.EQUAL, "UsrNameLookup", name);
                
                
                    var idFilter = this.Terrasoft.createColumnFilterWithParameter(this.Terrasoft.ComparisonType.NOT_EQUAL, "Id", this.get("Id"));
                    esqDuration.filters.logicalOperation = Terrasoft.LogicalOperatorType.AND;
                    esqDuration.filters.add("esqFirstFilter",nameFilter);
                    esqDuration.filters.add("esqSecondFilter", idFilter);
                    esqDuration.getEntityCollection(function(result) {
                   if (!result.success) {
                       this.showInformationDialog("Request error");
                       return;
                   } else {
                       result.collection.each(function(item) {
                               totalDuration += item.get("UsrDurationMinute");
                           }
                       );
                       // console.log("i am running");
                       // let prevduration=this.get("UsrprevDuration");
                       // console.log("previous duration"+ prevduration);
                       totalDuration += currentDuration;
 
                   }
                    console.log(totalDuration);
                   this.Terrasoft.SysSettings.querySysSettingsItem("UsrMaximumDuration", function(maxDuration) {
                       // console.log("td"+totalDuration);
                       if (totalDuration > maxDuration) {
                            this.set("Numbervalue", false);
                           this.showInformationDialog("No more than " + maxDuration + " total performances duration is allowed minutes.");
                            invalidMessage="No more than " + maxDuration + " total performances duration is allowed.";
                            return{
                                invalidMessage: invalidMessage
                            };
                       } else {
                           this.set("Numbervalue", true);
                            invalidMessage="";
                            return{
                                invalidMessage: invalidMessage
                            };
                       }
                   }, this);
 
               }, this);
            
                    
            }
                console.log(invalidMessage);
                return{
                                invalidMessage: invalidMessage
                            };
                },
 
 
The console.log(invalidMessage); statement always prints an empty string.

• The function returns <strong>invalidMessage</strong> before the asynchronous operations (getEntityCollection and querySysSettingsItem) complete.
• As a result, validation messages do not appear correctly.
