Hi Rahul,

 

The object TrainingEvent which you are trying to commit is coming as empty , please debug and check and add the condition if its empty then don’t commit.

Hi Rahul,

 

I can understand the error log, which is mentioning about the null object of the entity ‘TrainingEvent’ in ‘ACO_ADE_Registration_SetTotalNumberOfRegistrations’ cannot be changed.

 

#1 Check how you’re retrieving the TrainingEvent Object

#2 Before changing the values of the TraningEvent object, have an exclusive split and check for non-empty object.

 

Thanks!
