HI Manisha,
Ensure that you have  added the URL to CSP Errors whitelist using a wildcard like this: https://*.forcecontentuser.com

Also there is a known issue with the lightning:map usage which is worth checking: https://trailblazer.salesforce.com/issues_view?id=a1p3A000001FSlqQAG

Hi there.

In my lightning app I have a few components:
  • one component has a ui:inputSelect and registers an event. the ui:inputSelect has a change attribute that fires a function, wherein the selected text (an ID) is put in an event and fired.
  • one component that handles the event, is an aura:iteration list of a component that, on handling the event, should retrieve a list of items where a master-child lookup is the sent ID of the master object. This then displays all those child objects.
  • the other component that handles the event, has three inputText fields, that are supposed to display the other fields of the master object
The problem: either the event seems to not be fired, or the handlers seem to not be activated.

I put console.debug's, alerts and component.set("v.testmessage", "fired") 's in the handlers but they never execute.
I then put one of the handlers as the init-handler and then it did execute the handler (with an undefined ID since the event hadn't yet been fired, which is reasonable).

I have triple-checked the event name, event type and handler action, everything matches. I have no compilation problems, I have no errors when I am using my app. 
I also have no response whatsoever from my event. Any ideas?

**Registering component**
<aura:component controller="PrefixMasterHeaderSelectorController">
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />

Solved it...

After I found out that the firing component was able to handle the (component) event, but a component somewhere else (not a parent or child component, but, say, an uncle-component) was not, I changed the type of the event to application. Still didn't work, so I looked up the documentation and saw that an application-type event is registered slightly different.

<aura:event type="APPLICATION" >
    <aura:attribute name="item" type="sObject__c" />
<aura:registerEvent name="PrefixMasterEvent" type="c:PrefixMasterEvent" />

var applicationEvent = $A.get("e.c:PrefixMasterEvent");
    applicationEvent.setParams({"item" : itemID})
(Note: instead of component.getEvent("eventName") you now use $A.get("e.c:EventName") !
I'm not sure what the 'e' stands for, but I'm pretty sure the 'c' part is the namespace, and be careful to put the name of the event FILE as 'EventName' in the $A.get() parameter.)

<aura:handler event="c:PrefixApplicationEvent" action="{!c.doAnotherFunction}" />
(Note: the main difference is: with an application event there is no need (or use) for an event 'name', and I'm not sure why it has to be specified at the registerEvent tag other than it's a required attribute of the tag.)

    doAnotherFunction(component, event, helper) {
        var item = event.getParam("item");
        alert('The item is: ' + item);

Hi Experts,

I need some assitance with a date formula. I trying to calculate the number of months left between two dates, start and end date. I currently have the folloiwng formula:

(Custom_End_Date__c - today ())/30

Which will give me the number of days left and if I divide the number by 30 and I should get the numbner of months. Unfortunately I am short by one month. For example if I have a end date of 12/01/2015 minus today, 30 July, would give me 124 days. If I divide that by 30 I get 4 months, or more exactly 4.13 months. But from July to Dec is 5 months.

Any assistance would be greatly appreciated.

Best Answer chosen by Shane Quiring
Dividing by 30 is going to give you slightly inaccurate results because not every month is 30 days. 

If you are only concerned about difference in the actual month - ie July 30th to Aug 1st = 1 month
Try this:
(MONTH(Custom_End_Date__c) + (12*(YEAR(Custom_End_Date__c)-YEAR(TODAY()))) - MONTH(TODAY())

I just added a badge that i've already had in my LinkedIn profile.
You can go to your LinkedIn profile and under Add certificate -> Certification Name & Certification Authority (Salesforce Trailhead).

Best Answer chosen by Akshay Shrivastava

Hi Akshay,

You control record-level access in four ways.
Org-wide defaults specify the default level of access users have to each other’s records.
Role hierarchies ensure managers have access to the same records as their subordinates. Each role in the hierarchy represents a level of data access that a user or group of users needs.
Sharing rules are automatic exceptions to org-wide defaults for particular groups of users, to give them access to records they don’t own or can’t normally see.
Manual sharing lets record owners give read and edit permissions to users who might not have access to the record any other way.

I am a beginner with coding and looking for help

The code I have below works for getting 100% coverage and passes the trailhead evaluation however I also wanted to assert that the Error message is correct.

because I wanted to set up all test data outside of the starttest() and I wanted to check and valid insert as well as a invalid one I need to write the saveresults to a list. Everything works fine untill i tried to access the  error messages.
I have played with every variation but cannot figure out the syntax

system.debug(r1.getErrors());  gives me  DEBUG|(Database.Error[getFields=();getMessage=The Last Name "INVALIDNAME" is not allowed for DML;getStatusCode=FIELD_CUSTOM_VALIDATION_EXCEPTION;])

system.debug(r1.getErrors().getMessage);  doesn't compile " Initial term of field expression must be a concrete SObject: List<Database.Error>"
system.debug(r1.getErrors().getMessage()); doesn't  Method does not exist or incorrect signature: [List<Database.Error>].getmessage()

And so my tries Have gone on!

how do I get the getMessage field from the getErrors?

private class TestRestrictContactByName {
    @isTest Static void TestRestictedname(){
        List<contact> testcontacts = New List<contact>();
        contact c0 = new contact(LastName = 'Testcontact');
        Contact c1 = new contact(LastName = 'INVALIDNAME');
        Database.SaveResult[] srList = Database.insert(testcontacts, false); 
        Database.SaveResult R0 = srlist[0];
        Database.SaveResult R1 = srlist[1];

Please check below post for same issue

2) https://developer.salesforce.com/forums/?id=906F0000000BQwoIAG

you can try below code
public class TestRestrictContactByname {
    @isTest static void TestContactWithInvalidNameNotInserted(){
        String inputLastName = 'INVALIDNAME';
        Contact newContact = new Contact(LastName= inputLastName);	    
            insert newContact;
        catch (DmlException dmlEx) {
        	// Verify (Assert)
        	// In this case the insert should have been stopped by the trigger,
        	// so we need to verify that we got a dml exception (and specifically that we got the error message
            // that we were expecting).
        	String expectedMessage = 'The Last Name "'+ newContact.LastName+'" is not allowed for DML';
            System.assertEquals(expectedMessage, dmlEx.getDmlMessage(0));

Sample code 2:-
private class TestRestrictContactByName {

    @isTest static void metodoTest() 
        Contact c = new Contact(LastName = 'INVALIDNAME');
        Database.SaveResult result = Database.insert(c, false);
        System.assert(result.getErrors().size() > 0);
        System.assertEquals('The Last Name "INVALIDNAME" is not allowed for DML',

Hello everyone,

And i am sending file in body as a blob and also try in body but i can't sucess. so give me some idea that how i can solve this issue.

Box dot supports some common formate like csv,txt,etc which contains text type data, and you'll be easily able to do that but when you try to upload some file (Blob type) then you need to some work around for that.

Try below code it'll help you to upload your file to box.com
public static HTTPResponse uploadFile(Attachmnet file)
  String boundary = '__boundary__xxx';
  String header = '--'+boundary+'\n';
     + 'Content-Disposition: form-data; name="data"; filename="'+file.name
     +'"\nContent-Type: application/octet-stream\n\n';
  String footer = '\n--'+boundary+'--';
  String body = EncodingUtil.base64Encode(file.Body); //encodes the blob into a base64 encoded String
  body = header + body + footer;
  HttpRequest req = new HttpRequest();
  req.setHeader('Content-Type','multipart/form-data; boundary='+boundary);
  req.setEndpoint('http://posttestserver.com/post.php?dir=what_a_wonderful_post');   //COOL site to test form uploads
  Http http = new Http();
      return http.send(req);
