Hi,

I have created a custom button in VF, using commandButton.Clicking on this button should update a custom field.
Though, I have implemented this, I have couple of challenges.
1)How do I add this button on Object Page layout, such that it appears on the Object detail page?
 2)Clicking on the button, updates the field.But the updated value is not shown, until the page is refresh 
    I want, updated value to be shown, when button is clicked and without refreshing the page.
   Below is my controller extension class.
  

public class ControllerEx3
{
   private final Account acct;
   public ControllerEx3(ApexPages.StandardController stdcontroller)
   {
    this.acct = (Account)stdcontroller.getRecord();
   }
   
   Public pagereference Activate()
   {
     string stat;
     Account act;
     act=[Select name, status__c from Account where ID=:acct.ID];
     stat=act.status__c;
     if (stat!='Active')
     {
       act.status__c='Active';
       update act;
      }
     return new PageReference('/'+act.Id);
     
   }
 }

 

Hi,

My requirement is to create a contact , by clicking a button on the account detail page. Button click will open a new vf page with contact fields onto it.Account name field on new vf page must be auto popuated, where as rest of the contact fields can be typed in.
How do I achieve this?
 

How do I call a method from the controller extension to a custom controller?
Below is the controller extension class:-
public with sharing class ControllerEx1
{
   public final Account acct;
   public ControllerEx1(Apexpages.StandardController stdcon) {
   this.acct=(Account)stdcon.getRecord();
   }
   public Account returnAccount()
   { 
     
     return acct;
   }
     public PageReference Add_Con_Or_Opp()
     {
       PageReference pr = new PageReference ('/apex/ContactsOrOpportunity');
       pr.setRedirect(true);
       return pr;
     }
   }

I want to call returnAccount() from above CE to below controller method.
global without sharing class MyController2
{
   public Account acnt{get;set;}
  ControllerEx1 c=new ControllerEx1();
   acnt=c.returnAccount();
}
It throws an Compile Error: unexpected token: '='  at the last line

Hi,

I am trying to create an input component on VF page that would only allow pre defined formatting to be entered by the user.
First 3 chars should be from A-Z/a-z.Next 3 chars should be from 0-9.Next 3 chars can be alphanumeric.
I have written below 'MyController' and VF pages.
Public class MyController
{
 
  Public Account act {get;set;}
  public Account getaccount()
  {
   act= [Select ID, Name,Description FROM Account
             Where Id= :ApexPages.CurrentPage().getParameters().get('id')];
        if(Pattern.matches('[A-Za-z]{3}[0-9]{3}[a-zA-Z0-9]{3}', act.Description))
        return act;
        else
        {
          ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR,'Error: Invalid Input.');
           ApexPages.addMessage(myMsg);
           return Null;
        }
   }
   
   Public PageReference save() 
   {
     update act;
     return Null;
   }
 }

VisualForce Page-
<apex:page controller="MyController">
<apex:form >
<apex:PageBlock >
<apex:inputField value="{!act.description}" />
<apex:commandButton action="{!Save}" value="Save new description" />
<apex:pageMessages />
</apex:PageBlock>
</apex:form>
</apex:page>
When I execute above VF, through an ID. I get a text field and by entering description, when I try to save it. It give me below error.
Attempt to de-reference a null object. Error is in expression '{!Save}' in component <apex:commandButton> in page scenario4: Class.MyController.save

 

Hi,

How we can implement below validation on VF input field?
Create an input component on VF page that would only allow pre defined formatting to be entered by the user.
First 3 chars should be from A-Z/a-z.Next 3 chars should be from 0-9.Next 3 chars can be alphanumeric.
Is it doable without javascript or HTML5? If yes, How?
 

Hi,
My requirement is -A user shouldn't be able to create opportunites more than worth 100k in a day. I am writing a trigger in the apex class for this.Below is the code.
public class TriggerClass
{
  public void checkOpps(List<Opportunity> ops)
  {
    Double Total_Amount=0;
    for(Opportunity o1: [Select Amount from Opportunity where createdDate=Today AND CreatedByID=:UserInfo.getuserID()])
    {
      Total_Amount += o1.Amount;
    }
     for (opportunity o2:ops)
    {
    Total_Amount+=o2.amount;
    }
    If(Total_Amount>1000000)
    {
     o2.addError('You have exceeded Daily Limits');
     }
     }
     }

It thorws a compile error:  Compile Error: Variable does not exist: Amount 
When I comment the line-Total_Amount += o1.Amount, it gives an error-Loop variable must be an SObject or list of Opportunity  (for the first For loop).
What I am missing here.
Note- I know this can be done in many other ways, but I am interested in knowing reason for these errors in the above code

Hi,
I was trying below trailhead challenge for Bulk Apex Triggers.

To complete this challenge, you need to add a trigger for Opportunity. The trigger will add a task to any opportunity inserted or updated with the stage of 'Closed Won'. The task's subject must be 'Follow Up Test Task'.
The Apex trigger must be called 'ClosedOpportunityTrigger'
With 'ClosedOpportunityTrigger' active, if an opportunity is inserted or updated with a stage of 'Closed Won', it will have a task created with the subject 'Follow Up Test Task'.
To associate the task with the opportunity, fill the 'WhatId' field with the opportunity ID.
This challenge specifically tests 200 records in one operation.

I wrote below code:-
trigger ClosedOpportunityTrigger on Opportunity (after insert, after update) {
   List<Task> taskList = new List<Task>();
    for (Opportunity opp : [SELECT Id, StageName FROM Opportunity WHERE StageName = 'Closed Won' AND Id IN :Trigger.new])
   {
    taskList.add(new Task(Subject = 'Follow Up Test Task',
    WhatId = opp.Id));
    }
   if(taskList.size()>0){
        insert taskList;
        }
    }
It throws an error-Variable Doesn't exist:ID at line 6 (WhatID=opp.ID)
What, I am missing here?

 

Create an Apex trigger for Account that matches Shipping Address Postal Code with Billing Address Postal Code based on a custom field.
I am writing following code:-

trigger AccountAddressTrigger on Account (before insert,before update)
{
    List <Account> act= [Select id,name from Account where BillingPostalCode != NULL and Match_Billing_Address__c='True' ];
        For(Account a:act)
       {
           a.ShippingPostalCode=BillingPostalCode;
            }
}

It gives error-Varibale Doesn't exist:BillingPostalCode. 

What I am missing here?
Note- In the challenge, it's given, ShippingPostalCode and BillingPostalCode are the API name, 

Hi There,

I am writing a trigger to update a opporutnity related record, if any new /updated account doesn't have a one. 

trigger AddRelatedRecord on Account (after insert,after update) {
    List<Opportunity> oppList = new List<Opportunity>();
    
    // Get the related opportunities for the accounts in this trigger
    Map<Id,Account> acctsWithOpps = new Map<Id,Account>(
        [SELECT Id,(SELECT Id FROM Opportunities) FROM Account WHERE Id IN :Trigger.New]);
    
    // Add an opportunity for each account if it doesn't already have one.
    // Iterate through each account.
    for(Account a : Trigger.New) {
        System.debug('acctsWithOpps.get(a.Id).Opportunities.size()=' + acctsWithOpps.get(a.Id).Opportunities.size());
        // Check if the account already has a related opportunity.
        if (acctsWithOpps.get(a.Id).Opportunities.size() == 0) {
            // If it doesn't, add a default opportunity
            oppList.add(Name=a.Account + ' Opportunity',
                                       StageName='Prospecting',
                                       CloseDate=System.today().addMonths(1),AccountId=a.Id);
        }           
    }

    if (oppList.size() > 0) {
        insert oppList;
    }

}

It throws an error in line 15: Variable doesn't exist:Name.

What I am missing here?

Hi,

I am trying to display all accounts, and for each account, the first and the last name of each contact associated with that account.
I am trying below APEX code.
List <Account> Res = [Select Account.Name, (Select Contact.FirstName,Contact.LastName from Account.contacts) from Account];
For(Account a:Res) {
//System.debug('Account Name:' +a.name);
//System.debug('Contact FirstName:' +contact.firstname); 
//System.debug('Contact Last Name:' +contact.LastName);  
}
 It displays the account name perfectly fine. But for Contact FirstName, it displays: FirstName , similarly for lastname it displays:LastName.
What, I am missing, here?
