I've spent hours trying to figure this challenge out and finally got it working, but now when I go to 'Check' the challenge, it's not giving me the credit I deserve! The task seems pretty straightforward, but i'm sure i'm missing some code they think is necessary. Like the teacher telling you that you "solved the problem wrong" even though you got the right answer...

Error is: Challenge Not yet complete... here's what's wrong: 
The campingListItem JavaScript controller isn't setting the 'item' attribute correctly.

------ campingListItem.cmp ------
<aura:component >
    <aura:attribute name="item" type="Camping_Item__c" default="{'sobjectType':'Camping_Item__c','Packed__c':false}"/>
    <p>Name:
        <ui:outputText value="{!v.item.Name}"/>
    </p>
    <p>Price:
        <ui:outputCurrency value="{!v.item.Price__c}"/>
    </p>
    <p>Quantity:
        <ui:outputNumber value="{!v.item.Quantity__c}"/>
    </p>
    <p>Packed:
        <ui:outputCheckbox aura:id="checkbox" value="{!v.item.Packed__c}"/>
    </p>
    <ui:button label="Packed!" press="{!c.packItem}"/>  
</aura:component>


------ campingListItemController ------
({
    packItem : function(component, event, helper) {
        component.set("v.item.Packed__c",true);
        event.getSource().set("v.disabled",true);
    }
})

Hi, I am having trouble with the "Attributes and Expressions" module from trailhead.

Here is the challenge:
Create a Lightning Component to display a single item for your packing list.

• Create a component called campingListItem that displays the name (ui:outputText) and the three custom fields using the appropriate output components.
• Add an attribute named 'item' for type Camping_Item__c.

I created an component named campingListItem and this is the code:

<aura:component >
    <aura:attribute name="item" type="<my_domain>__Camping_Item__c"/>
    
    <ui:outputText value="{!v.item.Name}"/>
    <ui:outputCheckbox value="{!v.item.<my_domain>__Packed__c}"/>
    <ui:outputCurrency  value="{!v.item.<my_domain>__Price__c}"/>
    <ui:outputNumber value="{!v.item.<my_domain>__Quantity__c}"/>
</aura:component>

The error that I am getting is: "Challenge Not yet complete... here's what's wrong: 
The packingListItem Lightning Component's attribute tag doesn't exist or its attributes are not set correctly."

With this, I tried to create another component, with the name "packingListItem", but It didn't work.

Can anyone help me?
