I cannot reproduce this. Can you please make sure to use the current version of Kunagi and, if that is the case, provide more information on how you trigger the Exception, including:

• your browser and browser version
• an exact sequence of actions you perform to trigger the Exception

Funny, I can't reproduce this now either. For what it is worth I'm using Kunagi 0.14.1 and Firefox 3.6.12. If I remember correctly when I did this the first time both the begin and end field where blank on the next spring page. I use the calendar to pick the start date and tried to use the + button to increment the length of the length of the iteration. Now however I don't seem to be able to have the begin and end filed ever be empty.

Side Note: I can confuse it by setting the end date to before the start date. The length goes negative and the +/- buttons no longer work.

I experience exactly same error. However, I was able to cut&paste this error. Not that it will be very useful.

The sequence was creating a new sprint, setting title & description, then assigning a start date and then clicking on the + in the length field.

Setting the end date explicitly works.

I don't know where I can find the version number, but it I downloaded it the 12th of November.

There appears to be some kind of Wiki syntax being applied to my comment.

Where it says + it should have read +

I can not reproduce this problem. Can you tell us your Kunagi version. It is visible on the login page. If not, you have an version, older then 0.15.
