create Task with Apex code // Attempt to de-reference a null object

Hi,

I want to create a Task after saving a customer Object.
In my Customer Object I give a User FIeld: Editor.
I try with this Code

Code:
task.WhatId = Object.id;
task.WhoId = Object.Editor__c;
task.Subject = 'Other';
task.priority= Object.Priority__c;
task.status = 'Not Started';
task.description = 'New  Work';
insert task;

 And I become this failure:

Attempt to de-reference a null object

Do you have an Idea to help me?

Thx

Magda

Hello magda,

Unfortunately the WhoId can only point to a Contact or a Lead. This will not accept a User id. You can't use the WhatId because it will also not allow you to use a User Id in it. Within a task you can only use a UserID in a custom lookup field or the Owner field.

Can any body suggest how  create stand alone task using apex coding..

 

 

Is it possible that we can create tak inside the case....plz plz suggest.

You have to assign the user to the tasks "OwnerId" not its "WhoId", like follows:

 

myTask.OwnerId = myAccount.OwnerId;

 

*NOT* like this:

 

Task.WhoId = Account.OwnerId;

 

and also *NOT* like this:

 

Task.WhoId = Account.Owner.Id;

 

As that will likely assign it to the current user rather than the record owner.

I had the same issue as magda. The problem was that I had a trigger firing "before insert" that referenced Trigger.oldMap, which obviously doesn't yet exist. I fixed the trigger by adding "if (Trigger.isInsert)" set of logic to avoid references to Trigger.oldMap before insert.
