Hello All,

Having issue with camping Lightning component.

I have created Lightning componet saying 'camping' but I then deleted it (using File Delete) but still I see it is there in Lightning components (when I opened in classic from quick finder using Lightning components). The problem is now I am not seeing in File open to open it and when I am trying to create a new camping it says the name camping is already defined.

Please help me.

Thank you in advance!

Regards,
Ravi Gadi.
Hi,

I can't pass the challenge (https://developer.salesforce.com/trailhead/force_com_dev_intermediate/lex_dev_lc_basics/lex_dev_lc_basics_events). This is the error when check challenge:

Challenge Not yet complete... here's what's wrong: 
The campingList JavaScript controller isn't adding the new record to the 'items' value provider.


I tryed in the browser add new Camping Items and it's working correctly. The item is added to database and the list is updated.

This is my code:

campingList Component
<aura:component controller="CampingListController">

Hi 

Condition : While sending an email from cases the from address should be a particular address selected from the from addresses option.If that particular address is not selected then the validation message should display saying "pls select "<email address"> for sending an email "

How can i achieve with trigger
I'm following the example shown on Peter Knolle's post here: https://developer.salesforce.com/blogs/developer-relations/2015/03/lightning-component-framework-custom-events.html

When creating the contactSearch Component, I'm getting the following error:

"Failed to save undefined: No CONTROLLER named apex://mynamespace.ContactSearchController found: Source"

I'm not sure what I've missing - any thoughts?
