Review comment:
       This confused me while I was doing a technical code review of this PR, so I had a closer look at the existing code when I realized that this was just copy/pasted... it's already wrong in that existing code, I'm proposing to improve it in https://github.com/apache/fineract/pull/799.. would you be willing to rebase and change this accordingly, once that is merged?

Review comment:
       This `return null`here looks very curious... won't this hide problems, are we sure that the (commented out!) throwing of an exception wouldn't be better?
