{
"message": "Starting position out of bounds: -1",
"isSuccess": false,

Here, bundles is parent object. Can anyone let me know how to resolve this issue. Thanks

Hi,
I have three objects viz., qACC , qCON and qOLC. Now from these three objects, I have different fields as follows
qACC- 'Country', 'Year','Month'
qCON- 'Country__c','PROC_YR','PROC_MO'
qOLC- 'Coun', 'Pro_Year','Pro_Mon', 'Closed_Date'

In the third object i.e qOLC, I have 4th field Closed_Date that is not available in the remianing two objects. When I co-group these three objects, it is throwing me an error stating that mismatch of columns in co-group.
I tried giving null field in remianing two objects in co-group, but that didn't work.
Can anyone please help me achieivng this.

Thank you in advance

Issue with Co-grouping
Hello Guys,

I have a requirement where we need to cogroup 3 datasets which contains fields such as Country, year and month. But in the 3rd dataset, we have an additional field as Closed Date. This field will give result in the combination of Country, month and Year.

So in the co-group, for this 3rd dataset, if we include Closed Date along with Country, month and year., we are recieving this error "Mismatched number of cogrouped columns: 3 and 4"

Cogroup statement- 
cogroup qACC by ('Country', 'Year','Month'), qCON by ('Country__c','PROC_YR','PROC_MO'), qOLC by ('Coun', 'Pro_Year','Pro_Mon', 'Closed_Date');
 
Can anyone please advice on how to do this grouping or is there any other alternative to get this done.
 
Thanks,
Sastri

As salesforce old wave dashboards are getting expired in June'19, we have around 19 dashboards to convert to new dashboard design. As the old widgets and other components are not editable in old dashboards, I am unable to convert the dashboard into newer version. Also, these dashboards are built in 2016 and we do not have those requirements in order build from scratch.
Is there any other better solution to convert old wave dashboard to newer version.
Please help

I have a requirement where users need to log in to salesforce using external authentication provider. The configuration in Open-id authentication. I have created the connection in Auth.Providers along with all the required key, id, url and tokens. Salesforce has automatically created a registration handler. Using Test-Only Initialization URL, I have tested the connection and I have recieved the XML which states that the connection is working fine

Now, I need the users to log in using that provider and should be redirected to Home Page of Salesforce. How to do that? Please help.

Thank you in advance.

I have a requirement in **Wave Analytics** where I need to fetch records from Previous year when current year is completed. I have a field named Processing Year. It now fetches 2017 records which we have hard coded. But when we move to 2019, it need to fetch 2018 records. I have tried lot of options but nothing seems to be worked out. 

Something like Current Year-1 will work. 
Any help will be highly appreciated.

Thank you in advance

Hello Admins and Developers,

I have a requirement where the calendars should be shared based on role/profiles. For eg: I have a profile named Marketing. This Marketing profile user's calendar should be shared with Sales Manager Profile. Sales Manager Profile users can see Marketing profile user's Calendar.. I know I can do this using public calendars from  setup but I cannot find any button or option regarding this in Lightning. 

In Lightning view, a calendar can be shared with a user but I need a calendar sharing in profile level. I have also gone through Salesfoce's PDF document but didn't find it helpful.
Can anyone help me solving this in detail. 

Thank you in advance.

Below is my code.
 

public class AttendenceController {
    public Class__C selectedUser { get; set; }
    public student__c stu {get; set;}
    public string recid{get;set;}
    public List<Attendance_Tracker__c> contacts {get; set;}
    public class StudentWrapper {   
        public Student__c student {get; set;} 
        public Boolean absent {get; set;}
        
        public StudentWrapper() {
            this.absent = false;
        }
        
        public StudentWrapper(Student__c student) {
            this();
            this.student = student;
        }
    }
    
    public List<StudentWrapper> students {get; set;}
    
    Date day = Date.today();
    
    public AttendenceController() {
        students = new List<StudentWrapper>();
        
        for (Student__c student : [select Name, Class__c from Student__c WHERE Class__C!= Null]) {
            students.add(new StudentWrapper(student));
        }
    }

Hi Developers,
Quotes will be auto sorted in Salesforce classic but where as in Salesforce Lightning, it doesn't. So I came up with a tool from app exchange called Alpha sort. It works fine but the UI is clumsy and it is redirecting to salesforce classic for sorting of the quotes which annoys users. Moreover, this functionality is only available for one time use per Quote.

Hence, can anyone please help me with developing Lightning Component for auto sorting of Quote in Salesforce Lightning. Or is there any other alternative...?

Any help will be highly appreciated.

Thanks in advance,

Everything works fine here. I have replaced this vf page with standard New button and it works fine.

2) Save and Cancel buttons are working fine here. Can anyone help me with Save&New functionality with custom apex code.
3) In the above code, there is a field called "Target Sectors". It is enclosed under <apex:actionregion> tag. The name of this field is not populating on the page(Please test this code in your DE for better understanding).

Can anyone help me with above queries as I'm running out of time. Bieng a newbie, I couldnot able to catch what is the better solution for this.

</apex:page>

Everything works fine here. I have replaced this vf page with standard New button and it works fine.
1) But, I do not know how to bind edit button with this page as it has to pre populate values which were entered while creating new record.
2) Save and Cancel buttons are working fine here. Can anyone help me with Save&New functionality with custom apex code.
3) In the above code, there is a field called "Target Sectors". It is enclosed under <apex:actionregion> tag. The name of this field is not populating on the page(Please test this code in your DE for better understanding).

Can anyone help me with above queries as I'm running out of time. Bieng a newbie, I couldnot able to catch what is the better solution for this. 
Thanks in advance

Hello Developers,
Below is my code to find total number of contacts for an account. Everything works fine here. I need to write a test class for this code. Can anyone help me with this....

trigger TriggerCntact on Contact (after insert, after delete) {
	set<ID> accSet = new Set<Id>();
    if(trigger.isinsert){
        for(Contact Con : Trigger.new){
            accSet.add(con.AccountId);
        }
    }
        if(trigger.isDelete){
        for(Contact Con : Trigger.old){
            accSet.add(con.AccountId);
        }
    }
    List<Account> acclist = [SELECT Id from Account WHERE ID IN :accSet];
    List<Contact> conlist = [SELECT AccountId FROM Contact WHERE AccountId IN :accSet];
    list<Contact> listCon = new List<Contact>();
    list<Account> listacc = new List<Account>();
    map<String, Integer> conMap = new Map<String, Integer>();
    for(Account acnt : acclist){
        listCon.clear();
        for(contact cont : conlist){
            if(cont.AccountId == acnt.Id){
                listcon.add(cont);
            ConMap.put(cont.AccountId, listCon.size());
            }
        }
    }
    if(acclist.size()>0){
        for(account a : acclist){
            if(conMap.get(a.Id)==NULL){
                a.Total_Contacts__c	= 0;
            }
            else{
                a.Total_Contacts__c	= ConMap.get(a.Id);
                listacc.add(a);
            }
        }
        if(listacc.size()>0){
            update Listacc;
        }
    }
}

Thanks in Advance!!​
