First, thank you for creating jforum. I use it heavily in my classes.

BUT, at the University of Hawaii the current implementation is extremely unstable.

1. In grade book, each iterm appearing can be assigned a category. THis is critical for weighting and proper display. It appears that your current version does not carry forward the input of the categories during either UPDATE (of grades) or RELEASE (of grades). I have been told "jforum does not support categories". Even if "true", the update and release should "do no harm". At present they destroy input elsewhere. I assume that the operation to update is not an sql update but a delete/add pair and that the data module is not carrying over the field value for the forum.

2. Both release and update have been hugely unstable. Here is a current exception.


An error has occurred. For detailed stack trace, please see the page's source code triggered from RELEASE GRADES

could not delete: [org.sakaiproject.tool.gradebook.Assignment#475000]; nested exception is org.hibernate.exception.ConstraintViolationException: could not delete: [org.sakaiproject.tool.gradebook.Assignment#475000]

Another exception from UPDATE of grades

An error has occurred. For detailed stack trace, please see the page's source code.

could not delete: [org.sakaiproject.tool.gradebook.Assignment#475000]; nested exception is org.hibernate.exception.ConstraintViolationException: could not delete: [org.sakaiproject.tool.gradebook.Assignment#475000]

All summer long the IT staff have had to "fix" the database or something to get things to work.

Previous versions had none of these errors or issues.

Several comments, in no particular order.
  • We -the JavaRanch community- did not create JForum. We use it as the basis of our forum software, and we have this forum right here where people can talk about it, but if you want to speak with the creators of JForum, head over to jforum.net.
  • What does a class named "org.sakaiproject.tool.gradebook.Assignment" have to do with JForum?
  • I don't understand at all what you mean by "update", "release" and "grades". It sounds as if you're talking about something that has no relationship with JForum.


  • Ping & DNS - updated with new look and Ping home screen widget

    Patrick,
    Welcome to CodeRanch!

    The University of Hawaii has put up a document on their functions. Only the forum part is JForum. The other things in that document are from other tools. In particular, releasing looks like it goes with the "resources" tool. Either someone at your university extended JForum a lot or there are a bunch of tools linked together. Either way, you will need to talk to your local help desk or whomever supports the system.
