    When using the Group Choice plug-in with "Allow choice to be updated" set to Yes, it is a good tool.

    However if the above choice is set to No then students, once they have made a choice, are presented with a screen that quite user unfriendly. In the test I did, they see Your selection: 13 (or 12 depending on the choice made) which bears no relation to the choice they were asked to make, and they are not allowed to see the current composition of the groups.

    Are there any plans to improve this part of the plugin? It's a really useful plugin but this stops us making full use of it.

    Many Thanks.

    Hello,

    I recently did a major rewrite of this module. The interface is now more user friendly, and the teacher is now able to control privacy settings in a more consistent manner.

    Moreover, the Group Choice plugin now works in Moodle 2.3 as well.

    We find that the "Limit the number of responses allowed" is not working well and a few extra students can save their choices exceeding the group limit.
    The view.php is not designed in a “pushing” mode so that the limit is checked once when the page is loaded.
    More important, the save function is not checking the quota restriction.
    In short, it depends only a “pre" loading function” to dim/disable the radio button but his may not work in many cases.

    To regenerate the problem:
    1) Goto the GroupChoice with only 1 slot available
    2) Student A open in Firefox visiting the GroupChoice page; at the same time student B visit the same page using Chrome;
    3) Both students can save their choice making the limit invalid.

    Is there any fix for this problem?

    Amanda & Murphy,
    Can you update to the latest version (1.3.1 which I uploaded today) or download it from the "Source control URL" link and let me know if this solves your problems?

    Dear Nicolas, I've installed the ndunand-moodle-mod_choicegroup-053f42d.zip file but the problem is still there.

    Hello Murphy,
    Thanks for reporting back. The code indeed checks before (for display) and after (when the form is submitted) for the group limit, but an error in the code verifying upon submission (post check) escaped my attention. Please find the corrected version in the "Source control URL" link, or here as soon as the module update is approved.
