Sprint Taskboard - Internal Error

[global]

Hi,

After testing the plugin and changed some task issue situation to "closed" the sprint taskboard got an error. In my srpint I have 2 issues, one as "new" and the other "closed". Any clue? I don't know how to program in ruby to fix this...

Rendering /usr/share/redmine/public/500.html (500 Internal Server Error)

[global]

I discovered how to reproduce this error. In the default installation, the situation "new" is set to be the default. If I set this to "false" and no other situation field is checked to be the default, the error above occurs.

[bohansen]

You must have a default issue status selected. Even Redmine will complain if you try to create an issue and don't have that (although with a nicer error message):

No default issue status is defined. Please check your configuration (Go to "Administration -> Issue statuses").

[global]

Thanks for your answer. I didn't try to create an issue after changing this configuration, so I didn't see this message. But if this is imperative, shouldn´t be a good idea to show an error to the user instead of 'Internal Error', like redmine?

[retorquere]

We can't implement a full sanity check on redmine's configuration for every change. Really, Redmine ought to complain loudly when it lets you create this invalid setting anyhow. Or activerecord ought to get its act together and introduce support for proper relational schemas. rant rant rant. Anyway, I've added code that detects this and complains to the rails log; at this specific point in the rendering path there's not much else that can be done.

[global]

I agree that redmine should do the sanity check over this faulty configuration. Should we open a bug for this issue in redmine's project?

Thanks for adding information about this problem in the logs...

[retorquere]

I'm saying that we can't do this sanity check. It would bog down backlogs, and it's not our responsibility. But yes, I'd think opening a bug report (or feature request, can't tell how this would be viewed) on Redmine.
