A useless error message is shown if "Mark transaction as…" was used on a selection of multiple transactions in the ledger if the selection includes scheduled transactions which were not entered, yet (“the grey ones”). Reproducible: Always Steps to Reproduce: 1. Mark multiple transactions in ledger, including a scheduled transaction 2. Context menu -> Mark transaction as… -> Select something Actual Results: Warning dialog with useless error message "Error" and empty details Expected Results: Hard to say how KMyMoney should react in this case. Minimum resolution should be a better error message. Using KMyMoney from branch frameworks 04/02/2016. I do not think we changed anything here, so the issue is probably the same in the 4.x branch.
I was unable to select a regular transaction together with a scheduled transaction in the ledger view. This is on 4.x master branch. How did you manage to get there?
Maybe you have to be tricky: Create a normal transaction with a date which is after the one of the scheduled transaction. Select the normal transaction and click on an transaction which is above the scheduled one using a shift click.
I installed KMyMoney version 5.0.1 amd tried to confirm. Here, I can select multiple transactions including some with future date, and then right-click and Mark as reconciled or mark as cleared, and everything works as expected. Cannot confirm bug. Maybe it's been fixed?
