Sorry to be a pain (although I'm getting up there in terms of number of posts!) I was trying to create a puzzle earlier today. I went through and did the full creation, and it told me that the puzzle was successfully made. However, when trying to click on any of the links (puzzle/statistics), I get this error:

type Exception report

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.17 logs.

I don't know if this applies to all puzzle types, but I figured you might want to know about this.

Hey, quite the contrary, thanks for reporting the issue.

We were able to reproduce it... sometimes. During our bug hunt we found the cause of a nullpointer exception that also suddenly popped up somewhere and that has been fixed on the development site.

We will resume debugging tomorrow, but in the meanwhile it could help to log out and log in or restart your browser, or some exotic combination of the two.

If everything fails, feel free to email me a picture of the puzzle so I can implement it for you.

As a followup to this, this has been occurring when I have been attempting to post a Mintonette puzzle to the site. I was able to post a Futoshiki to the vestibule correctly tonight(and it did not give an error). However, after that when I attempted to post my Mintonette again, I got to the "Puzzle has been entered into the database" page, but clicking on the links actually takes me to my Futoshiki puzzle.

I'm not sure if it's just Mintonette or if other types are also causing problems. My wife's asleep on the couch, so maybe I'll try making a puzzle of a different type to test!

Edit: I finally got the Mintonette working, so it's not purely the Mintonette's fault!

It seems that the problem is solved. The reason why it occured is still a bit vague though, so I can't promise that it really won't happen anymore... please let us know if you still experience this bug.
