As a student, I can't add myself into the group by clicking on "becoming member of group xx". I am not part of any groups in the course. The next window keeps asking me to enter a password which I know there is NO password setup for the group (no lock icon).
Is there something I did wrong, or something wrong with the setting or code?
Thanks,
Bei
So it let's you select a group by clicking the "become member"-button and then says that it requires password even when the group has none?
Is your user enrolled in the course and what role (s)he has (if switched role to student)? Is your course using enrolment keys for groups? Are you absolutely sure that the group has no password set?

But if you did a clean installation, created a new groupselect activity and still got this bug, please let me know so I can check other possible causes.

Thanks for your reply. This plugin is upgraded from 2.1beta1 so it is not a clean install for sure. There are some data already associated to it.
The test case is very straightforward. I have same test case in our production (running 2.6.2 with group self-selection version 2.1beta1 (20111018)) and it works fine. The user is enrolled in the class as a student. The course is not using enrolment keys for groups. And the groups don't have password protected set. However, it fails on "become a member" in our development (running 2.8.3 with group self-selection version 3.0.4 beta - I just upgraded it).
I don't recall we have set up something like a master password for all groups in the older version. If do, which field in the db that holds it? I am wondering if the plugin upgrade inserts a not-null value into it for us.
Also, there are a few Oracle-syntax-errors in view.php, particularly the ";" in front of the closing single quote for sql cmd. Once I removed that ";", it works with our Oracle.
For example:
ORDER BY groupid ASC;';
WHERE g.instance_id = ?;',
Can you remove them in your source code and include them in the new release? BTW when is the next release?
Thanks,
Bei

I've the same issue with moodle 2.8.5 and the 3.04 beta (20150107) version of the plugin. I also upgrade moodle and the groupselect plugin.
I've got the following debug error message during a fresh install:
XMLDB has detected one CHAR NOT NULL column (password) with '' (empty string) as DEFAULT value. This type of columns must have one meaningful DEFAULT declared or none (NULL). XMLDB have fixed it automatically changing it to none (NULL). The process will continue ok and proper defaults will be created accordingly with each DB requirements. Please fix it in source (XML and/or upgrade script) to avoid this message to be displayed.

Maybe it will help you to fix the error.
Greatings,

That would be great if you can fix it from the source. I need the new version of this plugin asap for our Moodle 2.8.3 upgrade. Please keep me updated.
That "NULL" vs. '' (empty string) in the password field is what I have guessed too. Oracle is famous for being picky. Thanks Michael for bringing more info on it.
Cheers.
Bei
sorry for late response. I made the fixes and pushed them to the project GitHub repository: https://github.com/birrel/moodle-mod_groupselect
I'd appreciate if you Bei could confirm if it works now (I don't have an Oracle db) . I'll publish an official version here by the end of this week.

I have upgraded mine to 3.0.5 beta (in Moodle 2.8.3 with Oracle DB as the back end db), and very glad to tell you that it is working perfectly now, no oracle errors and no password hunting any more.
Thank you for your hard work.
Bei
also from me many thanks to you for your work. I also tested the plugin version 3.0.5 beta with moodle 2.8.5 and postgresql, and it works as expected.
Just one thing: In the mod_form.php I think will change the mforms for studentcancreate, studentcansetdesc & deleteemptygroups from true to false. Because I don't want to disconcert our teachers/lecturers.
Thanks a lot & Greatings,
Michael
There is another small point that I have to change for my system. I modified style.css with the following:
.mod_groupselect .edit, .text_to_html, td {
word-wrap:break-word !important;
/*word-break: break-all !important;*/
}
I am not sure why you chose "word-break: break-all" for td. It creates text wrapping in the word for all columns in the system (e.g. report logs). Maybe you have some reason?
Thanks again.

We have a "student clinic", where "Clinic" itself is a course. We wish to allow students to sign up to each of the 4 or 5 clinic sessions running each week, using a group for each clinic session (Tuesday 7-11am, Tuesday 7.30-11.30am, Thursday 8-11, etc). Ultimately we hope to tie the group membership with the Attendance module, so we can take attendance for each clinic session (or group) rather than having all students in the Clinic course appearing in all sessions in the attendance module.
$canselect = (has_capability ( 'mod/groupselect:select', $context ) and is_enrolled ( $context ) and empty ( $mygroups ));
and change it to;
$canselect = (has_capability ( 'mod/groupselect:select', $context ) and is_enrolled ( $context ));
