I am stuck on the https://trailhead.salesforce.com/modules/security-for-lightning-components/units/secure-your-lightning-java-script-code challenge.
After searching on the internet, I am unable to find a solution.  I found a link https://developer.salesforce.com/forums/?id=9060G000000UbhwQAC but I am not sure what solution in it works.  (And I found another web page referring this same url saying "Jeff" had found a solution..but it did not work for me.  Here is what Jeff first says:
Trying securing the description instead:   secureFilters.html(results[i].Description__c)

I tried that and get this message:  
Challenge Not yet complete... here's what's wrong: 
The 'LTNG_SecureFilters_Challenge' component does not appear to be requiring the secureFilters resource.

Further in the post the person who asked the question says this:   "That worked. Thanks."
And then he summarizes and says would this be OK:

​secureFilters.html(results)  

And Jeff replies, "Correct".  

So I tried doing this:  
                var results =   response.getReturnValue()  ;
                secureFilters.html(results) ;    
And this created an error.....
And I tried this (thinking that maybe it needs to be passed to a variable) :
                var results =   response.getReturnValue()  ;
                results =  secureFilters.html(results) ;
And this created an error.....

Can anyone please help?

Thank you,
Stuart

Challenge Not yet complete... here's what's wrong:  Changing the owner of the Account record failed to update the 'Account_Owner_Name_Process__c' field for the Case object . Make sure that the process is correct and that it is activated.

I've implemented the Process Builder on Account to update the Case.Account_Owner_Name_Process__c field if Account.OwnerId changes.

Hi All,

On 5/26/2017 I had created an email service within a new sandbox to test an email handler - everything was working just fine on that date. Then on 5/29/2017 I was no longer able to email the sandbox, receiving this error:

dhtest2@7g5j57uejkh4vt0bibcq1xco2hws8etoi9fuw21zizsshsahg.s-3l1wvmak.cs1.apex.sandbox.salesforce.com (dhtest2@7g5j57uejkh4vt0bibcq1xco2hws8etoi9fuw21zizsshsahg.s-3l1wvmak.cs1.apex.sandbox.salesforce.com)
Your message couldn't be delivered. The Domain Name System (DNS) reported that the recipient's domain does not exist.
Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that their domain isn't properly registered at their domain registrar. Give them the error details shown below. It's likely that the recipient's email admin is the only one who can fix this problem.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Could this be at all related to our internal network? We didn't change antyhing..  Or does this seem like a Salesforce issue? I am surprised that within 3 days it worked and then stopped working.  Anyone have any idea or perhaps has experienced this problem before in their instance?

I reached out to support but was told that email services are a developer issue, not something support can offer assistance with (even though it's a standard functionality).  Last bit of info - no matter what I use for the apex class associated with the email service, i cannot send any emails into the sandbox.  All Email is also enabled within the sandbox.





 
Hi, I am checking a challenge step and am being told (incorrectly, I think) that my org is not configured properly. it keeps saying:

Hello Everyone,

I have created visualforce email template and tagged to approval process which will get trigger to Approver when some one request for approval.
 
When Approver tries to approve/reject through the email he/she received, approval response is not changing accordingly in salesforce.

Can some one please suggest what might be the problem here. Is the problem with visualforce template or any ?

Thanks in advance!!!

 
Hi All,

I receive the following error when attempting to check the challenge for Apply Unit of Work

Challenge Not yet complete... here's what's wrong: 
The 'challangeComplete' method in the 'UnitOfWorkTest' class has not successfully passed all tests. Ensure that you run the tests and it passes successfully before attempting this challenge again.

However, when I run my code in Developer Console, my test passes.  Any ideas on the problem?  Here is the code:

@isTest
public class UnitOfWorkTest {
    @isTest static void challengeComplete(){
        fflib_SObjectUnitOfWork uow = new fflib_SObjectUnitOfWork(
            new Schema.SObjectType[]{
                Account.SObjectType,
                Contact.SObjectType,
                Note.SObjectType
            }
        );
        
        for (Integer i=0 ; i<100 ; i++) {
            Account a = new Account(Name= 'Test' + i);
            uow.registerNew(a);
            
            for (Integer j=0 ; j<5 ; j++) {
                Contact c = new Contact(LastName = 'Test'+i + ' ' +j);
                uow.registerNew(c, Contact.AccountId, a);
                
                Note n = new Note(Body='Test '+i + '' + j, Title='Test'+i+j);
                uow.registerRelationship(n, Note.ParentId, a);
                uow.registerNew(n, Note.ParentId, a);
            }
        }

        uow.commitWork();
 
        fflib_SObjectUnitOfWork uow2 = new fflib_SObjectUnitOfWork(
            new Schema.SObjectType[]{
                Account.SObjectType,
                Contact.SObjectType,
                Note.SObjectType
            }
        );        
        for (Account a : [SELECT Id, Name, (SELECT Id, LastName FROM Contacts), (SELECT Id, ParentId, Title, Body FROM Notes) FROM Account]) {
            a.Name = 'Test';
            uow2.registerDirty(a);
            
            Integer i = 0;
            for (Contact c : a.Contacts) {
                c.LastName = 'Test';
                uow2.registerDirty(c);
                
                a.Notes[i].Body='Test';
                uow2.registerDirty(a.Notes[i]);
                i++;
            }
        }        
        
        test.startTest();
        uow2.commitWork();
        test.stopTest();
        
        System.assertEquals(100, [Select Id from Account].size());
        System.assertEquals(500, [Select Id from Contact].size());
        System.assertEquals(500, [Select Id from Note].size());
    }
}
trigger should work for after insert , after update, after delete, after undelete 
 Thanks  in advance

I am still getting this error:

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


My App save the new record into the database and add it to the "items" list.
Thanks for your answers!




 
Challenge - Create a form to enter new items and display the list of items entered. To make our camping list look more appealing, change the campingHeader component to use the SLDS. Similar to the unit, style the Camping List H1 inside the slds-page-header. Modify the campingList component to contain an input form and an iteration of campingListItem components for displaying the items entered.
The component requires an attribute named items with the type of an array of camping item custom objects.
The component requires an attribute named newItem of type Camping_Item__c with default quantity and price values of 0.
The component displays the Name, Quantity, Price, and Packed form fields with the appropriate input component types and values from the newItem attribute.
The JavaScript controller checks to ensure that the Name, Quantity and Price values submitted are not null.
If the form is valid, the JavaScript controller pushes the newItem onto the array of existing items, triggers the notification that the items value provider has changed, and resets the newItem value provider with a blank sObjectType of Camping_Item__c.


My answer - 
<aura:component >
<aura:attribute name="items" type="Camping_Item__c[]"/>
<aura:attribute name="newitem" type="Camping_Item__c[]"  default="{ 'sobjectType': 'Camping_Item__c',

The campingList component isn't iterating the array of 'items' and creating 'campingListItem' components.

Please share the correct solution.
Challenge says "To pass this challenge, block all users' access to the Salesforce1 for iOS app or the Salesforce1 for Android app."

"Instructions say: From Setup, enter Connected Apps in the Quick Find box, then select Connected Apps OAuth Usage.
Click Block on the row for Salesforce1 for Android or Salesforce1 for iOS.
When you’re ready to reenable access to the app, click Unblock."

However, neither Salesforce1 for Android nor Salesforce1 for iOS appear in the list "Connected Apps OAuth Usage".  I do see this above "Connected apps that are installed but haven’t been used by anyone don’t appear in the list." So I tried to use the newly downloaded Salesforce1 app in my hands-on org but ... well, I can't. It won't let me log on without authorization token, which - as a Salesforce employee - is aligned to my Salsforce email, not my hands-on org email address. So ... I can't complete the challenge. Help?
Please help me resolve this challenge:

https://trailhead.salesforce.com/modules/apex_integration_services/units/apex_integration_soap_callouts

The Challenge is as follows:

Generate an Apex class using WSDL2Apex and write a test class.
Generate an Apex class using WSDL2Apex for a SOAP web service, write unit tests that achieve 100% code coverage for the class using a mock response, and run your Apex tests.

Use WSDL2Apex to generate a class called 'ParkService' in public scope using this WSDL file. After you click the 'Parse WSDL' button don't forget to change the name of the Apex Class Name from 'parksServices' to 'ParkService'.
Create a class called 'ParkLocator' that has a 'country' method that uses the 'ParkService' class and returns an array of available park names for a particular country passed to the web service. Possible country names that can be passed to the web service include Germany, India, Japan and United States.
Create a test class named ParkLocatorTest that uses a mock class called ParkServiceMock to mock the callout response.
The unit tests must cover all lines of code included in the ParkLocator class, resulting in 100% code coverage.
Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.

The error I receive when checking the challencge is:

Challenge Not yet complete... here's what's wrong:
Executing the 'country' method on 'ParkLocator' failed. Make sure the method exists with the name 'country', is public and static, accepts a String and returns an array of Strings from the web service.

Here is the code I am using:
public class ParkLocator {
    public static String[] country(String ctry) {
        ParkService.ParksImplPort prk = 
            new ParkService.ParksImplPort();
        return prk.byCountry(ctry);
    }
}

and
 
@isTest
global class ParkServiceMock implements WebServiceMock {
   global void doInvoke(
           Object stub,
           Object request,
           Map<String, Object> response,
           String endpoint,
           String soapAction,
           String requestName,
           String responseNS,
           String responseName,
           String responseType) {
        // start - specify the response you want to send
        ParkService.byCountryResponse response_x = 
            new ParkService.byCountryResponse();
            
        List<String> myStrings = new List<String> {'Park1','Park2','Park3'};
    
        response_x.return_x = myStrings;
        // end
        response.put('response_x', response_x); 
   }
}

and
 
@isTest
private class ParkLocatorTest  {
    @isTest static void testCallout() {              
        // This causes a fake response to be generated
        Test.setMock(WebServiceMock.class, new ParkServiceMock());
        // Call the method that invokes a callout
        List<String> result = new List<String>();
        List<String> expectedvalue = new List<String>{'Park1','Park2','Park3'};
        
        result = ParkLocator.country('India');
        // Verify that a fake result is returned
        System.assertEquals(expectedvalue, result); 
    }
}

Any help which can be provided is greatly appreciated.  If you could advise me at raadams173@gmail.com if you reply with a solution, I can log in to check it.

Thanks.

Hello All,
I have completed this challenge.

1-For this first you need to create a helper formula field(type-percent) 
Percent Completed :
(DATEVALUE( CreatedDate ) - CloseDate )/100


2- Then you need to create the actual formula field (type- text) by using the helper formula field.
Opportunity Progress :

IF( Percent_Completed__c <=25,"Early", 
IF(Percent_Completed__c <=75,"Middle", 
"Late"))

Thanks,
Nida
