Outstanding Issues
From XOCPWiki
This page is for enumerating and discussing any issues that appear to be problems or that could use improvement in the current version of Classroom Presenter for the XO. These are topics to discuss, either here or at our meetings.
NOTE: All bugs and issues are now being tracked in our Bug Tracking System. Please make new posts there instead of here. This page is being kept for reference.

Current
- (June 11, 2008) When a student joins a presentation, they receive the slide-deck as it was when the instructor first loaded it from the datastore. This will not include submissions that were not already in the slide deck and that were broadcasted before the newcomer joined. Can anyone confirm this? Or is the .cpxo file recreated every time the instructor receives a new submission? This latter case would be the obvious solution if it isn't already implemented.
- Yes, this is indeed the case. A more efficient solution would be rebuilding the .cpxo only when a new student joins before it is actually sent to them, and only if new submissions have been received since the .cpxo file was last built. The process takes a second or two, so if it was happening every time a submission was received, a class of 30 or so students all submitting at once could easily kill the instructor machine. Even with the more efficient solution, we'll have to be careful that if students are joining at the same time that submissions are coming in that we don't recreate the file while someone is in the middle of downloading it. --Brian 12:08, 11 June 2008 (PDT)
- (June 6, 2008) The navigation toolbar should state whether the activity is in instructor mode or in student mode. Also, when the instructor quits the activity, the student machines need to have their navigation unlocked before the instructor machine disconnects from the dbus tube. (Added these to Beta 2 target on the Timeline.)
- Is there a tab widget we can use for the Slides/Answers buttons? Buttons don't really feel like the right widgets for the job. Also, "Answers" should be "Submissions" instead; our goal is to facilitate collaboration, not simply answer questions. Similarly, the "Type answer here" text at the bottom should be removed.
- Resolved: Widget is indeed a button and the proposed changes have been implemented.
- The submission field at the bottom is cleared every time it loses and subsequently regains focus. This could cause a student to lose work.
- Resolved: This no longer happens.
- Submit button for the text field should (maybe) move to the activity sharing toolbar or the ink toolbar; the text field should get submitted along with the other annotations on the slide.
- Resolved: There is now a single submit button (checkmark button in right-side of ink toolbar) that submits both the text and ink.
- The sidebar recreates the thumbnail objects/viewer when switching between modes. This should be avoided, since it could be slow. Again, some sort of tab panel widget should accomplish this and allow the GUI to keep the original list of slide thumbnails around, just on a different tab that's not visible when the submissions are being viewed.
- Resolved: Thumbnail viewer is no longer redrawn when switching between "Slides" and "Submissions" views in the sidebar.
