Hi All,

Is it possible to drag and drop an attachment file from salesforce application to my local desktop?

There is an option in salesforce to download the available attachment, on top of this I want to implement the drag and drop feature also.
I have already explored the possibilities, this feature looks like browser dependent and I couldn’t find any more information with respective to salesforce.

Please let me know if this is feasible, has anyone tried this before? 

Thanks and Regards

Hello,

I'm having trouble checking the challenge, I've checked other discussions and I've done exactly what others have done to pass but everytime I click check challange it gives me this error message:

Looks like something went wrong, please try again later.

I've logged out of both Developer Edition and Trailhead acc, used another new Developer Edition to redo the challenge and it gives me the same message.

Hi,

I have written the below classes as part of the trailhead challenge for Apex REST callouts.

The class -

public class AnimalLocator {
  
  public static String getAnimalNameById(Integer id) {
    
    Http http = new Http();
    HttpRequest request = new HttpRequest();
    request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals/'+id);
    request.setMethod('GET');
    
    HttpResponse response = http.send(request);
    List<Object> animals; 
    String returnValue; 
    
    // parse the JSON response
    if (response.getStatusCode() == 200) {
      Map<String, Object> result = (Map<String, Object>) JSON.deserializeUntyped(response.getBody());
      animals = (List<Object>) result.get('animals');
      System.debug(animals);
    }
    
    if (animals.size() > 0 && animals != NULL && id < animals.size()) {
      returnValue = (String) animals.get(id);
    }
    
    return returnValue;
  } 
    
}

Mock Response Class - 

@isTest
global class AnimalLocatorMock implements HttpCalloutMock {
     // Implement this interface method
    global HTTPResponse respond(HTTPRequest request) {
        // Create a fake response
        HttpResponse response = new HttpResponse();
        response.setHeader('Content-Type', 'application/json');
        response.setBody('{"animals": ["majestic badger", "fluffy bunny", "scary bear", "chicken", "mighty moose"]}');
        response.setStatusCode(200);
        return response; 
    }
}

Test Class - 

@isTest
private class AnimalLocatorTest{
    @isTest static void AnimalLocatorMock1() {
        Test.setMock(HttpCalloutMock.class, new AnimalLocatorMock());
        string result = AnimalLocator.getAnimalNameById(3);
        String expectedResult = 'chicken';
        System.assertEquals(result,expectedResult );
    }
}

I have got 100% code coverage for the main class. But when I check the challenge I get 

Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.NullPointerException: Attempt to de-reference a null object

Please tell me if any changes to the code is required. It's really frustrating as I am stuck from past 3-4 days with this unit.

Thanks & Regards,

Curious what the best approach is to replace custom buttons that are currently using OnClick Javascript or URL since they are no longer supported when switching to Lightning Experience. Is it best to replace the classic buttons by building a new buton using the Lightning Design System framework within Lightning components and then adding to the page layout?

i want to display the custom error  message .how to solve the above solution please give any ideas.
