What does dereference mean? Posted on January 30, 2012 by mark. When you dereference a symbolic link, you end up with a pointer to the file (the filename of the target file). The term no-dereference is a double negative: It means reference. To no-dereference a symbolic link means to work with the link itself (do not dereference the symbolic. Imagine, if at the top of the loop, the iterator referenced the final element in the list. The whileIter statement will move the iterator to one past the end. You then dereference the iterator with (whileIter-filename), which is, of course, invalid and asserts.

Hi there I have created a cause that will revise a industry on Accounts when the child record is usually made or the very first child information (on Account) will obtain updated. However, my test class will be declining on the de-refence a null object and I'michael obtaining 91% coverage. how?

I thought it out why. All I need had been this.
for (Jobc work: Trigger.brand-new)
if(i0.id work.identity)
Account myParentAcct = parentAcct.obtain(job.Accountc);
if(myParentAcct != null)
myParentAcct.NewJobStartDatec = work.DateTimeTakenc;
revise parentAcct.beliefs;
And I required to designate in check class because it will be contacting another result in which is usually checking out for prior quantity.
work.JobNumberc = '000-00-00034';
job.Name = '000-00-00034';
It is usually working properly good with 92% code coverage. Thank you for your assist @RamuSFDC.

The only problem I can sense is certainly that the list size of we is never examined but the evaluation is produced. Please modify the code as below (strong text represents the adjustments)
result in NewJobTimeStampOnAccount on Jobc (after insert, after update)
Maplt;ID, Accountgt; parentAcct = new Maplt;Identity, Accountgt;; //Making it a chart instead of list for less complicated look for
Listlt;Idgt; listIds = fresh Listlt;Idgt;;
if(trigger.isInsert trigger.isUpdate)
for (Jobc childObj : Trigger.brand-new)
listIds.add(childObj.Accountc);
//Populate the chart. Also create sure you choose the industry you would like to revise, amount
//The kid relationship is more most likely known as jobsr (not really jobr) but verify
//You just require to select the kid work if you are usually going to perform something for illustration checking out whether the work in the result in can be the latest
if(listids.sizegt;0)
parentAcct = new Maplt;Id, Accountgt;(SELECT id, NewJobStartDatec, (SELECT ID, DateTimeTakenc FROM Jobsr) FROM Account WHERE ID IN :listIds);
Listlt;Jobcgt; i = go for id from Jobc where Accountc in :listIds purchase by DateTimeTakenc ASC restriction 5;
if(we.sizegt;0)
for (Jobc work: Cause.fresh)
if(i0.id work.identification)
Accounts myParentAcct = parentAcct.get(job.Accountc);
myParentAcct.NewJobStartDatec = job.DateTimeTakenc;
up-date parentAcct.beliefs;
//end ofif(i0.id work.id)
//end ofif(listids.sizegt;0)
Allow me understand if this set the issue.

Well, it's not giving me mistake when I operate/compile the program code. It't offering me mistake on the Test course. Right right now, it's failing at various other triggers written priviously. Right now, those sparks are created by additional admins before me at my organization. I attempted writing my code in a way that actually though it result in other sparks to proceed off, it should not really fail. Unfortunately, the check class can be failing over and over with the exact same de-refencing null object.
Question: when I run my check, should I become switching off all the some other triggers and check it? Also, when I set up should I deactivate all the additional leads to? This is definitely my first time composing and implementing program code so I'm not really too familier with the fomalities.

I thought it out why. All I need had been this.
for (Jobc job: Result in.fresh)
if(i0.id job.id)
Account myParentAcct = parentAcct.get(work.Accountc);
if(myParentAcct != null)
myParentAcct.NewJobStartDatec = work.DateTimeTakenc;
up-date parentAcct.values;
And I needed to indicate in test course because it is calling another trigger which is definitely checking for earlier amount.
job.JobNumberc = '000-00-00034';
job.Title = '000-00-00034';
It is working flawlessly fine with 92% code coverage. Give thanks to you for your help @RamuSFDC.

Hello, I have the same error message, but I am not sure, what else to consider treatment of.
My Program code is the using and the mistake is certainly in a test course
My Program code:
The Mistake Information:

First exception on line 0; very first error: CANNOTINSERTUPDATEACTIVATEENTITY, AddAccEuroAISNo: setup of BeforeInsert triggered by: System.NullPointerException: Attempt to de-reference a null object Result in.AddAccEuroAISNo: series 7, column 1: Course.MergeCasesController.mergeCases: series 181, column 1 Class.TestMergeCasesController.caseMergeTestMethod: series 48, column 1
Thanks a lot a lot in advance for any help

Initial of all, you should continually create a assistant class and call it from your cause. (greatest exercise)
2ndly, create your loops like this:
Contact cont : Cause.brand-new (since you are usually creating your program code in the trigger insdead of helper class).
3rm, check for thatMapIdToAccfor null value. Therefore after the for cycle add another IF situation to check whether the map will be null. Only implement the situation if chart offers a worth.
Test that and observe what happens.

Same error on my cause
i am trying contact name to end up being filled with customer name when a situation is made. the trigger gets preserved without any compilation error nevertheless when I was creating a Case and keeping it, punches error
