Throw error on changes during lead conversion

Hi i have a trigger to fire warning message when the first name and last name are interchnaged during conversion.

trigger LeadWarning on Lead (after update)
{
    for (Lead l:trigger.new)
    {
        if (l.IsConverted && trigger.oldMap.get(l.Id).First_Name_Kana__c==trigger.newMap.get(l.Id).Last_name_Kana__c && trigger.oldMap.get(l.Id).Last_name_Kana__c==trigger.newMap.get(l.Id).First_Name_Kana__c)
        {
           Trigger.new[0].addError('#####');
        }
    }
}


It should throw error only when the changed are made during conversion. but it is throwing error if the name is edited even before conversion. what is the missing part?

After update the record will be read only.. so do it with before update 
  
trigger LeadWarning on Lead (before update)
{
    for (Lead l:trigger.new)
    {
        if (l.IsConverted && trigger.oldMap.get(l.Id).First_Name_Kana__c==trigger.newMap.get(l.Id).Last_name_Kana__c && trigger.oldMap.get(l.Id).Last_name_Kana__c==trigger.newMap.get(l.Id).First_Name_Kana__c)
        {
           Trigger.new[0].addError('#####');
        }
    }
}

Hi all,

Thanks for the responses.
Even after i changed to before update, i get the error when the name is edited before conversion itself. Is there any other possible changes?

Hi Raghavi,
Below code can fullfill your requirements. Hope this will work for you. 
trigger LeadWarning on Lead (before update)
{
    for (Lead leadObj:trigger.new)
    {
        if (leadObj.IsConverted == true && trigger.oldMap.get(leadObj.Id).First_Name_Kana__c == trigger.newMap.get(leadObj.Id).Last_name_Kana__c && trigger.oldMap.get(leadObj.Id).Last_name_Kana__c == trigger.newMap.get(leadObj.Id).First_Name_Kana__c)
        {
           Trigger.new[0].Id.addError('test');
        }
    }
}

Please mark this as best answer if this solves your problem.

Thank you,
Ajay Dubedi
