Id not specified in an update call

Hello, well i have a request i have Contact that participate in one Event or More, now if the contact is already participatin i'm able to retreive his details in this participation and show them then modify if he wants to, but if he doesn't have a participation in any event  i can click on New button and Create new participation and my problem is when i click on Save it gives me an Error which is " Id not specified in an update call"

 

 

this is the methode for the New : 

public void NewRecord(){
isEdit=true;
related = new Related_Events_and_Reports__c();
}

and this is the methode for Save :


     public void save() {
        if (related == null ) {

              //means if it's new record insert it
              insert related;
      }
      try {

        else if (related != null ) {

// if the record already exist update it
      update related;
}

isEdit=false;

}catch(DmlException e){
ApexPages.addMessages(e);
}

 

now if i change in the if(related != null) TO  if(related.id != null){ update related; } it doesn't give me the Error but it doesn't insert in the Table

 

 

Any Help Please !!

Hi Jamal,

 

1. As you have initialize the object Related_Events_and_Reports__c

as related = new Related_Events_and_Reports__c(); //THIS LINE MEANS YOU HAVE GIVEN MEMORY TO THIS INSTANCE

so it can not be null;

 

I will explain it with example

 

Related_Events_and_Reports__c related; //MEMORY IS NOT ASSIGNED SO IT WILL BE NULL

Related_Events_and_Reports__c related = new Related_Events_and_Reports__c(); //MEMORY IS ASSIGNED AND CAN NOT BE NULL

 

 

It will alway goes in else if condition.

 

 public void save() {
        if (related == null ) {// CONTROL NEVER COMES HERE

              //means if it's new record insert it
              insert related;
      }
      try {

        else if (related != null ) { // CONTROL ALWAYS COMES HERE

// if the record already exist update it
      update related; // BUT AS YOUR RECORD HAS NOT BEEN CREATED IT WOULD NOT GET UPDATED
}

isEdit=false;

}catch(DmlException e){
ApexPages.addMessages(e);
}

 

 

2. now if i change in the if(related != null) TO  if(related.id != null){ update related; } it doesn't give me the Error but it doesn't insert in the Table

 

as related.Id will be null so it will not go into the elseif condition and hence not showing any error

 

Hope this has answer to your question.
