Null pointer exception

Hello All,

In the Data Modeling exercise Designing a data model, while following the Detailed steps and under Create the Vehicle information field group to identify the vehicle to service, when I go to step 10 and click on open to create a default user view I get a null pointer exception.

Would you know the reason behind this.

Thanks for your help

That is definitely unexpected behavior. As a workaround - and to help us diagnose the issue - can you select Create new view in that dropdown, then click Open, and see if that avoids the null-pointer exception?

Hello !


I have the same error for this exercise and the following one. I've got the same error when I create a group field.


I can't see where it might come from since I only follow the first steps that leads to create a group field.


Thanks for your help

Hi ,


Yes. I followed exactly the same steps. This might be an error in the exercise system. I am hoping if we can get some solution as future exercises are built upon this and its a show stopper.


 


Thanks,

I was able to resolve the issue. Below is what I was suggested.


1) Clear Cache of the browser and try with different browser. (sometime work, unfortunately it didnt work for me).


2) Dropped a note to SelfStudySupport@pega.com for help.


3) After a series of email conversation we got to webex screenshare .


4) I might be using same login to access previous and current exercise so I was told to go to option tab in the course curriculum and rest the training system.


5)Tried fresh again and the null exceptions were sorted.


 


Thanks,


Pradeep
