How can I display the results of my wrapper class in aura component? The debug of my apex controller shows me the correct results, but I can't pass the results to my component.


<aura:component controller="vlist" implements="force:flexipage:availableForAllPageTypes" access="global">        
    <aura:handler name="init" value="{!this}" action="{!c.doInIt}"/>
    <aura:attribute name="resultlist" type="object"/>
    <aura:attribute name="mycolumns" type="List"/>        
    <article class="slds-card">
        <div class="slds-box slds-theme_shade slds-p-around_none ">
            <div class="slds-text-title_bold slds-p-left_small slds-p-top_x-small slds-p-bottom_small">
                <lightning:icon iconName="standard:instore_locations" size="small" /> <strong class="slds-m-left--small">List</strong>
            <div class="slds-border_top slds-border_bottom slds-border_left slds-border_right">
                <aura:if isTrue="{!not(empty(v.resultlist))}">
                    <lightning:datatable data="{!v.resultlist}" 
                    <aura:set attribute="else">
                        <div Style="text-align : center">nothing</div>


    doInIt : function(component, event, helper) {
        component.set('v.mycolumns', [              
            {label: 'Account Id',   fieldName: 'AccId', type: 'text' },          
            {label: 'Account Name',     fieldName: 'AccName',   type: 'text' }, 
            {label: 'Count Opp',    fieldName: 'MyOppCount',    type: 'decimal' },      
            var action = component.get("c.vlist");                
            action.setCallback(this, function(response) {
                var state = response.getState();
                if(state === "SUCCESS") {

                    component.set("v.resultlist", response);
                } else if(state === "INCOMPLETE") {
                    //do something 
                } else if(state === "ERROR") {
                    var error = response.getError();
                    if(error) {

I think the problem is you are using List of AccList as return type of your function.But you are returning List of ResultWrapper. Update the return type of your function and see if it works or not. Also you are not returning anything. Return resultList from the method as well.

  • @prajjwl agrawal I changed my code and add a new list with name AccList2 and I changed the return statement to AccList2. Also I add the class AccList. But I don't know how can I pass the results of the resultlist to my component? I'm a beginner with components and wrapper.

    Instead of changing it to acclist change return type to List<ResultWrapper> and simply return your resultList Commented Nov 7, 2022 at 9:41
