Null Pointer Exception

[Former user]

Love this extension but just had a problem emerge suddenly when it was previously stable. Was using latest Moneydance along with v35 and just tried v36a with a manual install. v36a made no difference. Like I said, was previously stable after the upgrades and suddenly stopped.

Hope you can help.

Hi, Thanks for logging this and sorry it's causing you some trouble. I've had a quick look at the code and that NPE seems to be occurring because a parent transaction has no children, which should never be the case. So either something is wrong in Moneydance itself or I've misunderstood the Moneydance API.

I hope to be able to have a closer look at it this weekend.

Cheers, Kevin

I've just uploaded forecaster.36b.mxt to the downloads page. I still don't know why a parent transaction would have no children but I've modified the code so that it won't throw an exception but will log an error instead.

When you run this can you check your help console for an error message that starts with this: "A parent txn has a split count of 0"

It should then print some information about the transaction that might help me to figure out the bug.

Worked great, thanks. I checked the log and found a weird transaction in one of my accounts. It was a duplicate transaction of a scheduled transaction. The original (good) one had all the right info but the duplicate had a $0 transaction. I deleted the bad transaction and the error stopped coming up.

Nice one. Glad you're up and running again.
