Hi All,
 I am facing a issue with the trigger that I have developed.

When ever any new record is inserted then after the insert a custom field get updated. The update section of the trigger get fired up where I have written the code for before upate. Here, the fields does not reflect the value automatically. for ever record after insert I have to manually go and click edit and save to reflect the value.

Below given is the piece of code for the trigger. Please let me know what I am doing wrong with it.

trigger LeadTrigger on Lead (before update, after insert)
{
    List<Id> OwnerIds = new List<Id>();
    for (Integer i = 0; i < Trigger.new.size(); i++)
    {
           OwnerIds.add(trigger.new[i].OwnerId);
    }
   
    Map <Id, Id> contactAcc = new Map <Id, Id>();
    for (User u : [Select Id, Contact.AccountId From User where ContactId  != null and UserType = 'PowerPartner' and Id in : OwnerIds])
    {
        contactAcc.put(u.Id, u.Contact.AccountId);
    }
   
    Map <Id, Id> CAMs = new Map <Id, Id>();
    for (Account  acc: [Select Id,  OwnerId From Account where Id in : contactAcc.values()])
    {
        CAMs.put(acc.Id, acc.OwnerId);
    }

    Map<Id, User> userRecords =  new Map<Id, User>([Select Id, UserType from User where Id In : OwnerIds]);
    if(trigger.isBefore && trigger.isUpdate)
    {
        try
        {
            for(Lead l : trigger.new)
            {
                for (Integer j = 0; j < Trigger.new.size(); j++)
                {
                    if(userRecords.get(l.OwnerId).UserType!=null && userRecords.get(l.OwnerId).UserType=='PowerPartner')
                    {
                        l.CAM__c=CAMs.get(contactAcc.get(trigger.new[j].OwnerId));
                    }
                    else
                    {
                        l.CAM__c= null;
                    }
                }
            }
        }
        catch(Exception e)
        {}
    }
    if(trigger.isAfter && trigger.isInsert)
    {
        List<Lead> savedLeads = new List<Lead>();
        try
        {
            for(Lead l : trigger.new)
            {
                for (Integer j = 0; j < Trigger.new.size(); j++)
                {
                    if(userRecords.get(l.OwnerId).UserType=='PowerPartner')
                    {
                        Lead newLead = new Lead(Id=l.Id, CAM__c=CAMs.get(contactAcc.get(trigger.new[j].OwnerId)));
                        //l.CAM__c=CAMs.get(contactAcc.get(trigger.new[j].OwnerId));
                        savedLeads.add(newLead);
                    }
                }
            }
            update savedLeads;
        }
        catch(Exception e)
        {}
    }
}
