Vinay vinay The controller action marks the item attribute as packed, updates the item value provider and disables the button.
The controller action marks the item attribute as packed, updates the item value provider and disables the button is the task given in Trail head.
I have written the below controller to perform the action:
({
packItem : function(component, event, helper) {
event.getSource().set('v.disabled',true);
component.set('v.item.Packed__c',true);
}
})
This is setting the Packed__c to true but I am not passing the challenge.
but when I googled, below code was suggested:
({
packItem : function(component, event, helper) {
event.getSource().set('v.disabled',true);
var a = component.get("v.item",true);
a.Packed__c = true;
component.set("v.item",a);
}
})
But this code is not setting Packed__c to true. Please let me know the difference between two controller.

My question is:
how
var a = component.get("v.item",true);
a.Packed__c = true;
is different from
component.set('v.item.Packed__c',true);
That is not explained in above link which you had provided.

Hope this will clear the difference between the two.

You can use "set" as:
packItem : function(component, event, helper) {
event.getSource().set('v.disabled',true);
component.set("v.item.Packed__c", true);}
I have tested the same in my Dev. Org. and It is working.
Please mark this as best answer if your query is resolved.
