Can you, please, explain for me, why I have got this error:

Uncaught Error in $A.getCallback() [TypeError: Cannot read property 'apply' of undefined] throws at https://margaritabarabash-dev-ed.lightning.force.com/auraFW/javascript/hiaIVQRy4mbq1QTz7P5TfA/aura_proddebug.js:14722:9

part of my component markup:

<aura:component controller="FieldHistoryTrackingComponentController" implements="flexipage:availableForAllPageTypes,force:appHostable,forceCommunity:availableForAllPageTypes">

    <ltng:require styles="/resource/SLDS203/assets/styles/salesforce-lightning-design-system.css" />

    <aura:registerEvent name="appEventRefreshView" type="force:refreshView" />
    <aura:registerEvent name="DisplayAllHistoryEvent" type="c:DisplayAllHistoryEvent"/>

    <aura:handler name="init" action="{!c.doInit}" value="{!this}"/>
    <aura:handler event="force:refreshView" action="{!c.onReloadView}" />
    <aura:handler event="c:DisplayAllHistoryEvent" action="{!c.handleDisplayAllHistoryEvent}"/>
</aura:component>

My js-controller:

            var splitURL = url.split('/');
            id = splitURL[splitURL.length - 2];
            if(id.length == 18){
                id = id.substring(0, 14);
            }
        } else {
            id = url.substring(url.indexOf("id=") + 3, url.indexOf("id=") + 18);
        }
        component.set("v.id", id);

    component.set("v.AllRecords", false);

    var action = component.get("c.getHistoryRecords");
    action.setParams({

    action.setCallback(this, function(response) {

        else {

    $A.enqueueAction(action);

    });

    $A.enqueueAction(action);
}

})

Thanks very much for answer. I have not a clue what`s wrong with this.

I think it's this line that needs to be fixed:

if(id.lenght == 18){
    id = id.substring(0, 14);
}

Change lenght to length.

Generally the apply errors mean there is a javascript error - and that's what you have. Of course, there may be more, but this is currently the only one I can see.

Oh and make sure you don't try to write to window.location. Looks like reading from it is ok though.

  • Thank you for your answer. I changed lenght to length, but it did not help. I still have that error

  • Can you try to isolate the error to one particular area? At the moment, you have a huge dump of code there and it's hard to debug the whole lot. Sep 12, 2016 at 17:57
