SUMMARY The "calculate" button in the loan creation wizard works the first time but subsequently fails and gives error message: "You have entered mis-matching information. Please modify your figures or leave one value empty to let KMyMoney calculate it for you" if a number is modified post-calculation. STEPS TO REPRODUCE 1. Set up a new loan; 2. On the "payment" tab - enter numbers for loan amount, interest rate, and term 3. Push "calculate" --calculation done correctly - "Payment (principal and interest)" should now be filled with a value, potentially value in "balloon payment" depending on values used in test 4. Modified the loan term (example: add 12 months, or 1 year) 5. Delete both values previously calculated (balloon and payment) 6. Push "calculate" again to calculate new value based on modified loan term OBSERVED RESULT Error dialog appears: "You have entered mis-matching information. Please modify your figures or leave one value empty to let KMyMoney calculate it for you" EXPECTED RESULT A new calculation occurs incorporating modified term length SOFTWARE/OS VERSIONS Linux/KDE Plasma: Bodhi Linux running Moksha ADDITIONAL INFORMATION Because of this bug, the only way I can get the calculation to work post-modified loan is to start from scratch with the loan dialog.
